Comfort seats retrofit into A7/A6

[mobilejo]

If I got hold of a set of comfort (multi contour) seats from a C7, could I retrofit them into my A7?

I know they will fit physically to the floor mounting holes, but as the comfort seats are operated via MMI for some functions, I'm wondering if coding is a simple case of selecting the right options in VCDS (which I have) or if something more complex is required.

Has anyone done this already? Is it even possible to get all the functions working?

Thx, I'm on the verge of selling this car due to lack of seat comfort and this might be the only thing to prevent that!

[yas]

I don't see why this wouldn't be possible.

[mobilejo]

I'm pretty sure it is, but I can't be completely sure.

I may play around with VCDS and see if there is coding in there for comfort seats that can be activated.

If you bought a car of the quality that A6/7's are thought to be then why would they make a "comfort" seat? This implies to me that the other ones are not comfortable.

Same applies to steering wheels - there are so many kinds and it would probably be cheaper to agree on the best one for a sports sedan and then put it in all of their cars.

Very true, it shouldn't be required. But after 8 years and 10 BMW's (some with comfort seats, some with sports seats) I have learned that Audi S Line seats just aren't that great. At least for me (6'6). I was always okay in all BMW seats, even the basic sports variants.

comfort seats have massage and ventilation (and more adjustment?), hence the "comfort"

i don't think this implies the other seats are uncomfortable per se. although, living where I do, lack of ventilation can be pretty uncomfortable.

on a side note, I love this thread. it reminds me of how B5 and B8 forums (or name your platform that's been out a few years) eventually progress from "how much will my lease be?" to "i found a set of upgraded seats I want to retrofit into my car". the latter being far more interesting :)

It is frustrating. The non-Prestige models have very disappointing seats. Prestige seats are better, but still not what you would expect. In my opinion, they should have put the comfort seats without massage and ventilation in all the A6/A7 models, and made the massage and ventilation an option. Even if they had to raise the price of the car a little bit, that would be better than the current situation.

Yup. The standard seats in an A6 are not very good. My wife's BMW X3 is more comfortable.

FYI, the configuration you mentioned, the comfort seats without the ventilation and massage, is available elsewhere in the world.

[DB22]

It seems a fairly common opinion that the 6 has seats that are varying degrees of lousy. I have the heated and ventilated seats in the prestige and the seats are very poor, not only are they uncomfortable but the ventilation aspect is almost useless. They have 3 levels of vent: 1 = does nothing, 2 = just about feel it and 3 = it makes a lot of noise but still doesn't work like other manufacturers seats do.
It is, however, very curious that my A6 is the first car that I have owned that allows the heated seat to be enabled the same time as the ventilated seat. This allows the heated aspect to work very well as most seats just have a heating element but these seats blow as well.

It is not a good policy to charge extra for something that is inferior to what is alternatively available. You can get the basic lousy seats or pay extra for some heated and ventilated lousy seats or pay even more to get the seats that should have been provided in the first place.

It is similar to the entertainment system: you buy an A6 and you get a radio that is compatible to a Ford Fiesta. You can upgrade to a Bose and pay extra for a lousy radio or, for the price of an average Korean car, you can get a B&O. There are numerous threads regarding the after-market upgrade of the B&O so for $6500 you can still get a lousy radio.

They market steering wheels the same way: 1 - a lousy smooth leather wheel, 2 = a sport steering wheel with grippy leather and paddle shifters, 3 = a heated steering wheel that eliminates a useful button that allows different functionality and 4 = a flat bottomed wheel that should have been supplied in the first place. All of which have a space for a badge in the center spoke but they save .5 cents by leaving it blank. Unfortunately, they have dropped the 4 spoke wheel which I like because I frequently drive with hands at 8 and 4 and it allowed for a grip around the spokes. I would prefer the grippy leather, 4 spokes, flat bottomed, heated, with a selectable switch all with a badge in the blank spot.

While I'm on the subject of curious decisions, why market 2, 3 and 4 zone HVAC? None of these systems work very well but I digress!

I currently have the Sport Comfort seats, and the lumbar was much too obtrusive on my lower back even when all the way retracted. So today I figured out how to pull off the seat backrest cover (without breaking it - it's tricky). This exposed the seat guts from behind. I fitted vertical strips of foam on both sides of the seat-back between the lumbar support mechanism and the seat cushion, positioned so as to not interfere with the lumbar mechanism. This made the center portion retract relative to the sides, which fixed the lumbar problem. However, there was still too much extension of the whole lumbar region, with a "gap" in cushion at the base of the seat-back. To fix this, I stuffed a larger piece of foam at the base, and loosened up the lower ties to allow the leather to accommodate the extra foam padding. This worked wonders, and the seat is now comfortable, and the heating/fan/lumbar/etc functions all still work fine. I don't know if it just an "American" body shape/size problem (I'm 6', 200 lbs), but I had the same issue with my A6. I took a different route with the A6, and pulled out the lumbar mechanism tension springs, as well as added additional foam (custom fit) on the top-side of the seat and backrest, and covered them with custom seat-covers. This was very comfortable, but it eliminated the fan effects (not a huge deal) and made the heating more of an "eventually" option rather than instant feedback. On the minus side, it didnt' look the greatest with seat-covers, even though they did match the interior color. But I put comfort over looks as my cars are every-day drivers. Just my 2c worth for the more mechanically adventurous.

Adding the comfort seats (including ventilation and massage) is possible. I did this for my "summer seats". I have the S sports seats normally on my car, but on the summer because it is really hot i swap them with the comfort ones for the ventilation feature.

If you already have electric seats and memory than things are easier.

You need to get one more wire for each seat from the central electrics (12v) and then do the coding. Once you've done the coding all the functions will work as intended.

The only thing i didn't find how to activate are the MMI menus that show the massage features and seat cushions setup. These features work but without appearing on the MMI. I didn't dig too much about this since i only use these temporarily on the summer time.

There is also one component protection that you need to remove for the seat memory (which is connected to the steering wheel memory - if you have electrical steering wheel column).

Hope this helps.

Thanks for the info. Getting the MMI options don't concern me so long as I could actually still adjust the seat cushion features (bolster inflation etc).

I don't have electrically adjustable steering wheel, I do have memory and electric heated currently, so from what you are saying I would just need one extra wire from central electrics (live 12v) and I'm good to go?

Where do you access this wire and what did you connect it to?

Thanks!

[Oblivia]

Next time I have the VAG-COM out, I'll try to remember to check the coding options for the seats and post them. Don't know if that will help, as it may be the MMI (hidden options?) that needs to be modified to allow the functions to show.

[audi1]

I'm thinking about doing this comfort seat retrofit.
Can you post up does Vag-Codes for it ?

[audi1]

I bought a set of comfort seat for my A7 can anyone help me out with the wiring and coding to do the retrofit?

[Tomcat-R]

Oblivia

This is most commonly done by finding a car (new or used) with the desired options present from factory and cloning its module settings. Friendly people at the dealership can help with this.

[audi1]

I think there is very few A6/A7 with the multi-contour seats around but so far i found and option in 19 can gate way where you can add the multi- contour seats option.
I just need to figure out where a purple and a red/blue wire goes.

[netsecguy]

Audi1 - I too have looked into this. Had a shop tell me they could potentially hook up power and use the seat controls to control massage and adjustment, but not through the mmi. seems like we should be able to run through the mmi with the correct wiring harness. i've pulled my original seats and there are definitely fewer wires and relays. would like to find a salvaged s6/s7 or newer a6/a7 with comfort seats and pull all the wiring out for my car, along with the seats. i'm sure some vag programming may be required at that point though. best of luck!

[gta7]

Very interesting thread I am having a horrible time with my week old A7. The seats are killing my back about 30 minutes in to the drive.

I am hoping that the comfort seats could fix this. Dealer wanted me to trade in for an S8. Just a little bit more money ;)

The seats were the main reason I sold my A7 a few years back. Comfort seats or even the basic seats in the S6/S7 are a lot better.

[gta7]

Just hoping I get used to it. Nothing like researching the heck out of it and in the end looks like I made a very big mistake with these seats.

[audi1]

I couldn't get used to mine and didn't want to listen to what most people was saying that it might not work so i bought a service manual and figured out wiring and put the seats in and tried the bolster button and what surprise the MMI screen popped up displaying the multi contour seat with full function.
now i will be contacting Jack kirry to have him remove CP......

Just curious, how much did you pay for them?

[audi1]

ADVANCE AUTO SALVAGE sells them for around $600.00 each

[audi1]

Well my Multi contour seat retrofit is 100% complete.
Jack kirry is a very very cool guy he work with me 3 nights for over 2 hrs each night to get it done.
we were having issues with my laptop with windows 10 the first night then wifi the second night and today he got it done with laptop with windows 7 that i used.[up]

[RRF985]

Congrats on getting the swap done. Will you be writing a How-to by chance to help others out?

[audi1]

I will be more than happy to help out anyone but i just didn't take pictures or did any write up since i wasn't expecting it to work.
It's not hard to do and you don't have to go to the dealer to remove the CP.

What is CP ?
And why did you remove it, seems that you have more options with it ? :-)

[audi1]

Component Protection.
I didn't remove them, the options that the seats have the car will display.

[durfA4]

This makes me wonder about the feasibility of adding the A8 seats to my A7. The S7/S6 seats are not available in velvet beige. I could pick up a set of the comfort seats and plug them in. I was thinking about something sport, but all the features seem nice as well.

Interesting. The comfort seats in my S6 have all the options. I didn't realize they made a comfort seat without the massage and other adjustable parts.

[gta7]

Well this is awesome news. The dealer quoted me $14k to do the install.

[morski]

As far as im aware the A8 comfort seats fit the A6 as well. Someone over on a german forum iirc has done it

[audi1]

I don't think i would like the A8 seats in my A7 but i definitely will be adding the massage option to my seats soon.
I will do a write up on the wiring when i take it a part again.

[audi1]

Your headrest is motorized? I know my seat belts are motorized and might need to be coded.

[audi1]

Webtoker are your headrest electronic ? i know my seat belts are electronic and might need coding but the headrest are manual no motor.

Na but the bottom of the seat extends out and there is massage functionality along with other features.

[audi1]

Ok. The massage option is the only option that i am missing then cause i have the bottom of the seats that extends and bolster that deflate and inflate when exiting or entering the car.

[audi1]

I added the 2016 shifter to compliment me seats.
i find the install a little more easy if you take the top off and push down the leaver.

[Cuore]

Hi all,
I recently bought a set of comfort seats for my car from eBay. I have been driving car with leather interior for over 10 years, so I just couldn’t get used to car without them.

But, there is an issue. There is green, black and red (+airbag) connectors in my car floor and harness with same connectors (green, black and red) in my current standards seats bottom. In comfort seats there is only black and red connectors, no green at all. However, seller said to me that there is heating, but it is powered possibly via black or red connector.

There is already electrical lumbar support in my standard seats, so I have understood that the comfort seat adjustment (moving and tilting) would work fine without additional cables, just plug-in. But what about the heating?

There is also memory in both comfort seats, but I understood that would require much more retrofitting and cabling. It is not necessary feature for me, all I need is the seat to move and heat.

[morski]

The comfort seats use the LIN BUS to activate the heating units in the seats. You need to look at the correct wiring diagrams and tap into the LIN BUS already in the car and code the car to Comfort seats. The red and black connectors should be same except that fully powered seats have a thermal fuse fitted whereas powered lumbar only seats are direct to fuse box on side of dash panel. Upping the fuse ampage from 7.5 to 10A usually works ok.

[Cuore]

Thanks morski! I think I will need more your help. I have VCDS and I have done some retrofitting earlier, so this should not be an impossible task to do.

My friend has same Audi, but his car is with standard electrical seats (memory in driver’s seat). I did some studying between these 3 type of seats.

Standard (passenger) and Standard (driver):
Black (reference)
Red (reference)
Green (reference)

Standard, electrically adjustable (passenger) and Standard electrically adjustable with memory (driver):
Passenger: all same three connectors, with wires on the same places
Driver: Green and black are the same. In red there is 3 additional wires.

Comfort, electrically adjustable with memory (passenger) and Comfort, electrically adjustable with memory (driver):
Both: No green, black are the same. In red there is 5 additional wires.

Conclusion:
- As the standard normal and standard electrical all wires are the same, the seat moving and tilting won’t require anything, just plug-n-play
- As there is 3 additional wires in standard memory seat compared to standard (electric, non-memory) seat, it is assumable that these 3 wires relates to memory function. Memory function is not necessary for me, so these 3 wires can be left aside.
- When comparing standard memory seat and comfort seat there is only two additional wires. Would it be possible that these wires relates to heating function in comfort seats?

Other issues:
- So there is only 4 wires in red connector of standard seat. If you unplug the connector, you can see that there is only the same 4 contacts in mating connector. Meaning that if you connect comfort seat, no signal will come to these additional two wires. Is it even needed?
- I found some seat adapter cable from Kufactec, but I don't know what is it for? https://www.kufatec.de/shop/en/Audi/A7-4G/Seat-Heating-Harness-Audi . I've tried to contact them, but yet haven't got comprehensive answer.

Morski, do you think that some additional wiring is required or what did you mean? Fuse change and some coding required of course. Is that LIN BUS something you can play with VCDS or something else required?

Does anyone have any wiring diagrams that relates to these seats? Could someone with comfort seat check me some VCDS coding for the seats?

Here is an image of the connector: http://imgur.com/vtoiRfh (I don't know why, I cannot include it in this topic)

http://imgur.com/vtoiRfh

[Cuore]

Btw. Could someone with heated comfort seats confirm, that there really is no green connector used under the seat (it is 1 minute job.) It’s just that if there really is no heating, all of this study is worthless. It can get even -30 degrees Celsius here in Finland and not having heated seats is not an option. Kufatec just informed me, that if there is no green connector, then there is no heating. I don’t know if this is a 100% sure information, but I would want ensure this information.

[Cuore]

Could anyone with seat heating check if there is that green connector or no? I’m really starting to think that there is no heating in my seats. I have got mixed up information about the connector. Some say, the comfort seat heating is powered via red connector, some say black. I know for sure, that if there is green connector, there is heating. At least in these seats: http://www.ebay.co.uk/itm/Audi-A6-4G-Leder-Sitze-Ausstattung-Lederausstattung-SHZ-Memory-Titangrau/201436367858 there is that green connector and I’ve seen that in other comfort seats as well. I really doubt there would be two kind of heating connectors available for same seat. What do you think?

[morski]

Hi,
ive done a little checking msyelf have noticed the same thing with some seats having the green connector and others without. The wiring diagrams also show heating elements a well but comfort seats seats have the heating elements already attached to the back of the leather hence you can not buy the replacement elements for these seats.
I did a similar retrofit a while ago on an A5 but this had ventilated seats but not massaging. Again no green connector but when i pulled the seats apart to install the airbags etc the elements were there. Unfortunately the install is still not finished as im waiting to get the car back to remove CP from the heater panel as it was changed so can not confirm if its 100% sorted.

Have you studied all the wiring diagrams and compared each pin no on the connectors to the colours?/

[Cuore]

I’ve tried searching for wiring diagrams, but haven’t found any. That would help a lot. However, I did contact member “audi1”, who have done similar retrofitting. Did get some info, but unfortunately, that did not solve case yet. Discussion still ongoing.

At this point, first thing would be to find out, whether there is heating or not. How to tell? And if there is heating in my seats, my best guess is that I should figure out where to connect red/blue + purple wires: http://imgur.com/vtoiRfh

[morski]

I need to see better pictures than that one with correct colour of wires going to which number on the plug otherwise its random guessing

[Cuore]

I uploaded the pictures in high-resolution: http://imgur.com/a/OuKbd (open the picture in new window to get it bigger).

But, no need to guess anymore ;) Colours are:
6 = purple
9 = black/green
11 = brown
12 = green/black
13 = orange/green
14 = orange/brown
15 = red/black
16 = brown
17 = red/blue

- 9, 11, 15 and 16 are connected in my standard seats.
- My friend has electric driver seat with memory (heating via green connecter) and that seat red connector has also 12, 13 and 14 connected (in addition to those 9, 11, 15 and 16)
- His electric passenger seat has all the same wires as my standard seat (black, red, green).
--> This led me to conclusion that those 12, 13 and 14 would propably relate to memory function?
--> Which leaves me pins 6 and 17, that I guess would possibly relate to heating?

[morski]

Ok this the wiring for the RED connector:

13/14- CAN wires
12- memory
9- lighting
16-earth
15-power- power seat
17-power for multi contour seat control unit
11 earth for light

There is NO connection to pin 6 so why you have it i have no idea. You haven't mentioned what year your car is or what year the seats are but i have checked A6, A7, A8 wiring diagrams and also physically checked an A6 wiring loom that had multi contour seats fitted with RSE, memory,ventilation and again no pins in 1-7

The ONLY violet wire within the seat loom is the massage button but this is only an internal loom connection and does not go 'OUT' to any of the plugs

pictures of seats and from underneath would help 'a bit maybe?

[Cuore]

Seats are from 2014 Audi A6 3.0TDi and my car is 2011 2.0TDI. Please note that the connector I have been referring to is the connector in seat harness, not the mating connector on car floor.

I have got some info from member “audi1” as well. His seat connector also has that purple in pin #6. About that he said: “That's only if you will install the two button memory switch on the passenger door.” I planned not to install memory at all, so that can be left aside.

But what comes to other wires you mentioned:

13/14- CAN wires
12- memory
9- lighting
16-earth
15-power- power seat
17-power for multi contour seat control unit
11 earth for light

There is already wire in mating connector for wires: 9, 11, 15 and 16, but pins 12, 13, 14 and 17 are missing wire.

- #17 +12V has to be wired to this, no problem
- #12 relates to memory. I will not install memory function, so not relevant
- #13/14 CAN wires, what do these control?

At least “audi1” said he had all the same pins in red and black seat connector and no green connector at all. Yet though he has heating function.

Are #13/14 CAN wires needed for heating function? I’m just still wondering, that in which wire goes the signal to heating unit to tell it to “heat ON”, as there is nothing connected to green connector.

I can snap a few photos in the evening.

[Cuore]

Morski, could you also tell me what are the pin description in black connector?

I think I would also need the adjustment visible in MMI. How else can go scroll through the multiple adjustments that seat provides? Otherwise it's done blind. One might think those CAN wires are needed for that?

What about the VCDS coding, what needs to be done?

Here are some photos from seat bottom:

[Cuore]

Ok, so CAN wires are needed. I got most of the things sorted, but something is still missing.

I would need to know, where are the CAN wires connected: actual location, connector + pin number? What about VCDS coding?

[Cuore]

I did some studying and come to following conclusion:

There is a CAN gateway module under passenger kick panel and there will be orange/green and orange/brown wires connected and those are led to some existing devices. So, I just tap into these wires and make wires to both seats.

I made a drawing about the connection: http://imgur.com/8fNOdi7

1) Is this the right way to connect it. Have I understood correctly?

Played a bit with VAG COM. With VAG COM those seats (#88 and #89) should be selected from 19-CAN Gateway "installation list"? : http://imgur.com/36dz2S3

2) Anything else that needs to done with VAG COM?

[morski]

Yes thats right, Just make sure you connect the correct the colours to the existing ones otherwise you will end up with the seats on the powertrain or infotainment bus etc.

yes thats right for the gateway 19. Also you should see another 2 modules appear in your module list in VCDS for the L & R seats and you need to make sure that there isnt any 'odd' coding in there. I dont think you will need to change anything in there and suggest you dont just yet. You will see a few faults in there for CP for memory and positions not being learned etc. but the seats will still work.

Go through the modules in vcds i cant remember at the minute but you need to recode one/more modules for comfort seats and ventilated etc

I believe yours are ventilated so your front AC panel will need to be changed to one that has the vent button under the seat heating button. Again CP will on the replacement panel.

[Cuore]

Help needed!

Test setup done today and passenger seat was tested. Temporary wiring was done for #17 power and CAN wires. Moving functions were working and I was able to connect the seat control module via VCDS. All I did with VCDS was select that seat installed from CAN gateway module. I checked the seat coding, but the codes were not documented, so I'd have to do it blind.

I was not able to bring the additional pop-up "comfort" adjustments to MMI screen. Nor I was able to activate the heating. When I pressed heating on, heating signal lights stayed on for a few seconds and then shutted down.

At this point what is critical for me, is to verify that there really is heating. If there is not, then this all is worthless.

Morski, could you possibly check the neccessary coding?

Edit: Member "audi1" was saying that the Component Protection should be removed. Is it something that could block these features? How is it done?

The comfort seats use the LIN BUS to activate the heating units in the seats. You need to look at the correct wiring diagrams and tap into the LIN BUS already in the car and code the car to Comfort seats. The red and black connectors should be same except that fully powered seats have a thermal fuse fitted whereas powered lumbar only seats are direct to fuse box on side of dash panel. Upping the fuse ampage from 7.5 to 10A usually works ok.
Fuse burnt today. It was only 5A. Replaced and now working again.

About that heating thing, what is this LIN BUS you have mentioned? What and how I should do to that?

[morski]

The LIN BUS you will need if you want to activate the seat ventilation and it will also need a replacement air con panel with the extra buttons on it. How and if it is connected to seat heating issue i am not sure.
I do know that the comfort seats have the mats attached the bottom of the leather and can not be replaced and the heating works through the controller fitted under the seat. The power is there from before and what you have added but the controller needs to be told to turn the heating on hence a coding issue provided you have wired it 100% correct. this where the CP for the controller might need removing as well in order for you to proceed.

There is some coding in vcds ( for some reason i cant add images??) in the Central Electronics module 09, Byte 23 shows you 4 options to enable seat massaging w/o memory and seat ventilation w/o heating. These are the Only options i could find when i had a look yesterday at mine and whether toggling these might kick in heating i do not know for sure as i have not done this on the 4G platform only the B8 model.

OH! just thought also look at module 08 HVAC as there should/might be coding there too.

[Cuore]

I’m not sure whether I have understood the general principle of LIN bus. CAN bus is connected to seats and only free contacts without wires connected are #6 and #12. #12 is for memory for sure and #6 is that mysterious purple one, which supposedly relates to memory switch.

The question is, where do you connect the LIN bus or is it something virtual?

Edit: I was googleing LIN bus and this image came along: https://www.aenea.org/jsw/rls.png

There is only 1 wire for LIN bus and I came to think what if that #6 purple wire is for that purpose after all?

Edit2: See this Audi service training manual, page 50 http://cycle-planet.com/canbus/971603.pdf

It really seems that #6 violet wire is for LIN bus :)

[Cuore]

Still haven’t found out what is the purpose of that purple wire. It seems odd that there would be both LIN and CAN bus connected to seat. Above mentioned were just my speculation :) Might as well be, that it does not even need to be connected...

Anyhow, wiring and all the needed crimp contacts etc. should be clear at this point. Then there is these few installation things open.

1) Would anyone know what are fastening torques for front seat bolts (to chassis) and seat belt buckle? If you have any info, spit it out, it does not have to be A6 C7. I think those are pretty much the same, no matter which model.
2) Airbags should be installed too, and I was wondering if the airbag module should be inserted into this "pocket/pouch" that is there? See this picture: http://imgur.com/a/85PMn . There is holes on the same places where the module is fastened to seat frame and there is also nothing like this in standard seats. Why else would there be such?

[morski]

The LIN BUS is not not the violet wire on your plug. It will be a violet with a white stripe. They can exist side by side with can bus as they are 2 different systems. I cant access my newer wiring diagrams to check for 2014 onwards but up to 2013 there is no lin bus used on the comfort seats on the a6. You can always go online yourself with erwin audi and pay a few euros for wiring diagrams and download them too.
The pocket does look right for putting the airbag into. Whilst you have the seat covering hald off you should be able to see the heating mat attached to the back of the leather

[Cuore]

The LIN BUS is not not the violet wire on your plug. It will be a violet with a white stripe. I had the same impression about that wire. Also, at least member “Audi1” was saying, that the purple wire is not needed. Other only not-connected wire is the memory wire, so no purposles wires are left.

I did some snooping around last weekend. I peeled the seat upholstery from back a bit and yes, there were heating mats and wires visible :)

[popilam]

Hello,

On the red connector the pin assignment is:
6 = purple - unknown
9 = black/green - footwell lamp +
11 = brown - footwell lamp -
12 = green/black - to door module pin 16/T20e
13 = orange/green - can high on convenience can
14 = orange/brown - can low on convenience can
15 = red/black - power SA44
16 = brown - earth
17 = red/blue - power SB5

You need to code in HVAC memory seats modules left and right
Yo need to go to central electric and remove heated seats left and right from coding
You need to recode door control modules for memory seats
On can gateway ad memory seats and multicont seats front
Ventilation won't work without climatronic comfort, which is very hard to retrofit.
I wasn't able to code the MMI for seats adjust popup menu, as i have MMI low version.
And very important, you have to remove CP from seats modules

You will get massage, memory, heating and electric adjustment. Ventilation and contour seat menu won't work.

[Cuore]

Hi popilam,

I sent you private message with some questions :)

[Cuore]

Comfort seat retrofit project has proceeded well. Front seats have been installed, heating and moving functions are working just fine. I could not have found the correct coding for the seats to get comfort settings to pop up. Issue is that, all reference cars are equipped with MMI high, where as mine is MMI low. Also that the MMI module coding is completely undocumented, none of the bits are described. Changing the coding would be completely done blind.

I refused to accept that, I would not have the functionality. I did found a similar car (comfort seats and MMI low) from one car shop near by. That car did present the comfort settings, so I took the car for a test drive and hooked up with VCDS and read the codes.

I compared my coding to that car coding and found four interesting bits under module 5F that could have affect on the comfort setting. I tapped all the bits on and rebooted MMI. Oh, the joy, the settings did pop up when I spinned the seat selector switch :D The settings worked just like in the test car I drove.

After that, I started one by one to remove the selected bits to determine which of the 4 bits actually had affect on that. Once I had unchosen all the bits, MMI did no longer present the settings and with the switch in the seat you could adjust the comfort setting that was last selected after starting to remove the bits: drivers seat had bolster adjustment working, where as passenger seat had lumbar support working, nothing else could be adjusted.

I tapped all the bits on again, but the MMI did not present the comfort settings. It gave fault code:

I tried to remove it, but it comes back every time. I also removed all other fault codes, but it not fix this. With this fault code, I traced that 2 out of 4 of these bits selected gave the fault code, where as 2 did not have affect on it.

What could be causing that fault code? Only thing that came to my mind, is the Component Protection, but what suprises is that, why did it work for a while.

[popilam]

You didn't remove component protection from seats module?
The coding you posted is the one for comfort seats? The one you copied from the other car? I will try tomorow on my car to see if the popup menu appears on the mmi screen.

Component Protection can add really strange limitations, but the fault code Communications Disruption I dont belive is generated by CP.

popilam and mobilejo - did you get the menu in radio ?

[popilam]

Hi,
Yes we did. On 5F you must select bit 7 on byte 6 and you get the menu working.
Of course you have to remove CP on seats modules.

[Cuore]

My car had CP removed yesterday and popup menu works now. Only thing I did, was that I selected that bit 7 on byte 6, in module 5F. Please note that, this is for MMI low only. If you have that high resolution 7” screen, then the coding is different quite sure. At least the coding is many bytes longer.

It is possible that the Communication Disruption fault code might have been due to wrong coding as well. Popilam seemed to have it too earlier, even though he did not have CP active. I dont get that any longer, with CP removed and that one bit selected only.

I also bought a HVAC panel with ventilation buttons, and I can tell that those work too. Memory button and panel for drivers side also installed. What still needs to be done, is to connect the wires for the memory under kick panel. Then it should all be there :)

[Cuore]

Quick help needed!

I'm right now trying to wire the memory wire to driver door.

There is green/black wire in the door module, pin 16. I removed left kickpanel and removed the cover tapes from wiring harness that comes from the door, see http://imgur.com/a/2Uyi5

But there is no green/black wire there where to connect.

Where I should suppose to do the connection, what I'm missing?

[morski]

Take the green/black from your car seat module to the A Pillar connector and insert a new pin. On the door loom side fit the corresponding pin and take that back to the door module. From there it goes to the door memory switch
Now if you have a wire in some pins trace this back to the point where there are pins missing and fit new ones back to where they need to.

Do you have the wiring diagram for it?

[Cuore]

Referring to picture attached. There is already a green/black wire connected to door control module and I have already a wire coming under the seat under to kick panel, waiting to be connected, as soon as I know where.

Problem is that the green/black wire in door control module looks like it goes inside the car with all other wires, but there is not that same wire coming inside the car - see picture attached.

So, should I need to push the wire all the way inside the door, via feed through and cut the wire that is already there?

I do not have a wiring diagram, but I already know it is pin 16 in door control and there is already a wire.

[morski]

so where does the pin 16 from the 20 pin door module go? have you checked?

[Cuore]

so where does the pin 16 from the 20 pin door module go? have you checked?
That is what I would want to know ;) Wire is connected in pin 16, but I don't see it coming inside the car with all other wires http://imgur.com/a/2Uyi5

[morski]

pin 16 should be going straight to pin 5 of the 23 pin a pillar connector, this mates up to pin 26 on the car side 27 pin connector. Then connect pin 26 to the seat !!
not sure why you or anyone does these without wiring diagrams!

Then what would be the point of having supporting fellow Audists? [;)] Honestly, I did not found the diagrams and I was not willing to pay for the whole service manual. Are you able to buy such separately, where?

Anyway, opened the feed through connector in A-pillar. There was nothing connected in pin 5, so I wired the memory wire direct to that. I had the wire from seat already under kick panel, just in case. One bit on in door control module and that’s it.

Project is now 100% completed and everything functional. Only feature I did not include was the memory button for passenger side – I did not see it necessary.

Thanks to you morski and all others as well for the indispensable help!

[Marc R]

Very nice!

Could you make a how-to for cars with fully electic supersports interior?

My guess is this will be easier to do.

[Cuore]

I don't know what fully electric supersport interior is, but sure, if you have such as memory function already, then there will be less wiring.

Actually I had done a connection table for myself - it was a tool for me, to get the wiring done properly. I had lot's of information pieces from different persons, but not such round-up. One big issue was to find correct pin contacts.

This was done to 2012 Audi A6 Avant LHD. I'm certain the wiring will be the same in most of the A6's (and A7's), but ensure it yourself if you are not sure. I will not take the responsibility ;)

I did not do a write up about the installation itself. To me, that was quite clear.

Here is the connection table: https://i.imgur.com/ToRCe0c.jpg

If anyone tries this, I'm happy to give support regarding wiring and installation itself.

[80leu]

heloo
Cuore , pleas tell me, i put a set of confort seats in my car a6 2013 . seat are whit heating memory and contour control but not massage or ventilation.
I connected the can low and can hi to where intra-pillars down all combings, i tied red-green wire to positive and black green wire memories I linked it not still in the socket terminal 5-pin 23 column A.
Question: should not make any setting can blindly through the button on the seat lumbar?
And I wanted to know if I check something wrong or not until I reach the audi representative to remove CP?
tank you

[Cuore]

And I wanted to know if I check something wrong or not until I reach the audi representative to remove CP?
Before getting the CP removed, you should check if everything has been connected correctly. To do this, you must use VCDS to check that you can find 4 new modules (2x comfort + 2x memory) connected in the CAN bus. If these are not found, then you should re-check the wiring.

Component protection only prevents memory function to work and comfort settings to appear. Seats should still move and tillt, and the heating should work too.

[80leu]

Modules are present. the heating, move up/down,tillt is work. not work lumbar and side support-pneumatics. So why do I worry that

[Cuore]

not work lumbar and side support-pneumatics.
These are the features that won't work when the component protection is on, even if you try to do it blind. After you get the CP removed and add the coding, it will start to work ;)

[mjfloyd1]

I think a member was in contact with someone in Europe who remotely helped him remove CP.. Unfortunately I can't remember who it was

[80leu]

ok
in a few days i finish, then i tell you what happens
tank you for info

[lucian_1985]

Hi all, let me give you some info about my project for retrofitting comfort seats into my A6 C7.
First of all, I have the 2013 3.0 TDI biturbo model sedan (non facelift) and I have fitted the interior from a 2015 sedan (facelift). Ideed, I see a lot of people talking about the purple wire that goes into pin 6 of the red plug, this is a big question mark for me also because I do not know where it goes and what it does.....it is absent from all ELSA wiring diagrams that I have checked (facelift and non facelift models, sedan and avant, different engines, etc) for all types of seats. I also looked in the LIN BUS diagrams and it does not appear. Clearly, I did not run this wire anywhere but still all seems to work just fine.

My interior was electric with driver memory, so on the drivers side I only had to run 1 extra positive wire to pin 17 of the red plug for the comfort option, this is all on this side.

On the passenger side, apart from the positive wire previously mentioned, I had to run 3 extra wires, 2 for CAN connection and 1 to the door control module. The passenger memory module is connected in paralell for CAN with the door control module according to ELSA, so these 2 wires were welded to the existing wires that come from the A pillar; I disconnected the "interior part" of the plug that goes to the door and welded these 2 wires to the existing wires that go to the CAN. The 3rd wire was inserted in the same plug in the corresponding location. I was surprised to find that from this A pillar plug all the way to the door control module, the wire was already there (the one that comes from the memory module under the seat).....maybe if you have driver memory already installed, the door wiring comes already equipped on both sides. After, I ran the 8 wires for the memory button to the door control module and this is all for the passenger side.

With CP active on the seat modules, the memory function was not working on any side, the comfort function appeared on the MMI straight away when flipping the rotary knob (I have 3G+ navi high) but only the part under the legs was moving forwards or backwards. The options under the comfort menu in the MMI were too many, meaning that my interior is only comfort ventilated, but the option for massage, electric seat belt and another backseat option were visible....this was corrected automatically after CP removal, only the 3 options for lumbar, sides and legs remained. This info I see is automatically sent from the seat module to MMI according to the seat option, if I choose in the seat module the massage function, even if it does not exist, it appears in the MMI. So clearly, the MMI menu for comfort comes from the seat modules.

For the coding part, I have done absolutely no coding under 5F module. My coding now is : 050100000103FBEF7DB4CF1E00000003080001000000000000
For central electrics 09 there is only I thing to do, uncheck the boxes for seat heating, because now as the green plugs are missing, the seat heating is not controlled anymore by the central electrics, but by the seat modules. My coding now is: 0907A01109749FF2B98100C0A0001800CF9CC308AE08020100 0108546F21
I did not touch the new modules 06, 36, 88 and 89, they come already coded.
The climate control needs CP removal also, the module should come already coded for the "seat modules installed" part, you should only choose your options in the other bytes according to your car (engine, body, parking heater installed or not, rear seats heated or not), so basically you will do a mix of the 2 codings. My actual coding is 369100B824 (3.0TDI V6, sedan, with parking heater, with rear seat heating, no sunroof.....)
Last but not least, the door modules need coding, here the bits are not documented so we are in the blind, but I found the coding from a similar car with both memory modules and compared the coding:
Address 42: Door Elect, Driver (J386) Labels: None
new Coding: 011F1E215E00628202080013
old Coding: 011F1E015E00628002080013
Address 52: Door Elect, Pass. (J387) Labels: None
new Coding: 011F1E215E00628202080002
old Coding: 011F1E015E00628002080002
Only the 2 highlighted bytes from each module were changed.

So this is all, a few pictures with the interior and the car [:D]

Question on a similar topic guys....I've got heated and lumbar support front seats but not powered adjustable (mine are adjusted manually).

If I found a pair of powered A6/A7 Sline seats, could I just swap them in? Would the wires/harness already be in place in my car for simple plug and play or no?

p.s I don't care about memory seats and don't want that function

2013 A7

[lucian_1985]

Yes you can and they are plug&play. The only problem would be that the power to the seats comes from different "sources", if you have only lumbar then power comes from a standard fuse to each seat, I believe 5A or 7.5A. If you have power seats, positive comes from a thermal fuse (15A or 30A) located outside the normal fuse panel and this is designed for the extra current needed for moving the seats. The section of the wire is the same in both cases, 1.5mm². Some say that by changing the classic fuse that you have with a 10A-15A will resolve the problem, otherwise the existing fuse will blow out quite fast. If you want to go the right way and change the power wire and fit the thermal fuses, I can help with ELSA schematics.

[BenMTL]

Thanks for that info Lucian :)

So basically my options are;

1) Just upgrade the fuse and hope it works

2) Rerun a stronger wire


#2 is a lot of work so hopefully #1 would work, but if does not, could you post the ELSA diagrams here? Thanks in advance! [:)]

[lucian_1985]

Here are the diagrams for driver and passenger, the thermal fuses are S44 and S46, you have a picture showing their location on lower part of A pillar. Thermal fuse code is 443937105B (15A), fuse holder is 4A0937530. You have to run power to the thermal fuses with 2.5mm² wire; power comes from the 150A fuse on the battery (S133) and goes to the relay holder under the central electronics module 09 which is below the dash, under steering wheel (B316 Positive connection 2 (30a) in main wiring harness), you can connect there, you will find the 10mm² power wire.

Hello, been looking for seats for my A7 TDI. Seats are looking pricey on EBay, anyone have an extra set of seats swapped out for comfort seats? Or know of a place selling sport/comfort seats for a decent price?

Bought a water logged A7, my seats are rigid and peeling from the water damage. Should I swap out the seats for comfort seats or buy a pair of carbon fiber race seats for $800? Worth the hassle to switch to comfort seats?

[durfA4]

So I bought a pair of seats for my A7. They are the fully loaded comfort A8 w/ massage.

https://uploads.tapatalk-cdn.com/20171103/949868d88beb88a6f4f0fafd979d2758.jpg

They bolt right in, or they would if they came with the seat module. So I can’t move the seat.

I was able to find the correct module that the seat needs from eBay.de. I’ll need to figure out how to wire it.

The stock seats have red, green, black, and yellow airbag connectors. The comfort have red, black and yellow. So I’ll look at the pinouts and make sure that I match the correct wires to the new seat.

There are A7s in Europe with massage seats so I know it will be possible. I doubt the headrest control will be active. I’m sure it may work out.


Sent from my iPhone using Audizine (http://r.tapatalk.com/byo?rid=87676)

[Cuore]

I've struggled with the wiring about a year ago, but I was able to finnish the retrofit perfectly. I made a short connection table and instructions of it (already on previous page): https://i.imgur.com/ToRCe0c.jpg . Hope this helps someone.

durfA4: sound quite strange that the seat control module would have been removed? Are you positive that those are missing, both have their own? It's quite well fixed under the seat.

[durfA4]

Installed the passenger seat with the A8 massage seat 4H0959760E module. No extra wires ran and I was able to move the seat and install. No coding or anything. I did loose heat function which I knew would happen from the previous posts.

I’m gonna try to pull my A7 base memory/ lumbar 4G8959760 module and plug it into the passenger seat then install the A8 module in drives seat along with the correct wiring adaptations.

Check the green connect under the seat if you have connected it and it isnt loose. I lost seat heating as well and I just needed to push in the green connect to make it work again. Dont think you need new harness. Just check it out.

[durfA4]

Ok I have the seats installed.

They move and memory works (re used A7 seat module for drivers seat 4g8959760)

I need to get the CP removed for the A8 module.

Does anyone have massage in the A7? I don’t know if it was an option. Maybe in Europe.

I still need to jump the green harness to pin 17. Then I’ll figure it out

Did you end up getting this working properly yet? I just ordered a pair of a8 seats to install into my a6 Prestige which already has the heated/cooled seats. I’d be interested to hear exactly what you ended up doing.

[A6sport]

So I bought a pair of seats for my A7. They are the fully loaded comfort A8 w/ massage.

https://uploads.tapatalk-cdn.com/20171103/949868d88beb88a6f4f0fafd979d2758.jpg

They bolt right in, or they would if they came with the seat module. So I can’t move the seat.

I was able to find the correct module that the seat needs from eBay.de. I’ll need to figure out how to wire it.

The stock seats have red, green, black, and yellow airbag connectors. The comfort have red, black and yellow. So I’ll look at the pinouts and make sure that I match the correct wires to the new seat.

There are A7s in Europe with massage seats so I know it will be possible. I doubt the headrest control will be active. I’m sure it may work out.

DurfA4, I missed this one... have you started the work yet?

Edit: Just saw a previous post, that you did the install... nice.

[A6sport]

Hi all, let me give you some info about my project for retrofitting comfort seats into my A6 C7.
First of all, I have the 2013 3.0 TDI biturbo model sedan (non facelift) and I have fitted the interior from a 2015 sedan (facelift). Ideed, I see a lot of people talking about the purple wire that goes into pin 6 of the red plug, this is a big question mark for me also because I do not know where it goes and what it does.....it is absent from all ELSA wiring diagrams that I have checked (facelift and non facelift models, sedan and avant, different engines, etc) for all types of seats. I also looked in the LIN BUS diagrams and it does not appear. Clearly, I did not run this wire anywhere but still all seems to work just fine.

My interior was electric with driver memory, so on the drivers side I only had to run 1 extra positive wire to pin 17 of the red plug for the comfort option, this is all on this side.

On the passenger side, apart from the positive wire previously mentioned, I had to run 3 extra wires, 2 for CAN connection and 1 to the door control module. The passenger memory module is connected in paralell for CAN with the door control module according to ELSA, so these 2 wires were welded to the existing wires that come from the A pillar; I disconnected the "interior part" of the plug that goes to the door and welded these 2 wires to the existing wires that go to the CAN. The 3rd wire was inserted in the same plug in the corresponding location. I was surprised to find that from this A pillar plug all the way to the door control module, the wire was already there (the one that comes from the memory module under the seat).....maybe if you have driver memory already installed, the door wiring comes already equipped on both sides. After, I ran the 8 wires for the memory button to the door control module and this is all for the passenger side.

With CP active on the seat modules, the memory function was not working on any side, the comfort function appeared on the MMI straight away when flipping the rotary knob (I have 3G+ navi high) but only the part under the legs was moving forwards or backwards. The options under the comfort menu in the MMI were too many, meaning that my interior is only comfort ventilated, but the option for massage, electric seat belt and another backseat option were visible....this was corrected automatically after CP removal, only the 3 options for lumbar, sides and legs remained. This info I see is automatically sent from the seat module to MMI according to the seat option, if I choose in the seat module the massage function, even if it does not exist, it appears in the MMI. So clearly, the MMI menu for comfort comes from the seat modules.

For the coding part, I have done absolutely no coding under 5F module. My coding now is : 050100000103FBEF7DB4CF1E00000003080001000000000000
For central electrics 09 there is only I thing to do, uncheck the boxes for seat heating, because now as the green plugs are missing, the seat heating is not controlled anymore by the central electrics, but by the seat modules. My coding now is: 0907A01109749FF2B98100C0A0001800CF9CC308AE08020100 0108546F21
I did not touch the new modules 06, 36, 88 and 89, they come already coded.
The climate control needs CP removal also, the module should come already coded for the "seat modules installed" part, you should only choose your options in the other bytes according to your car (engine, body, parking heater installed or not, rear seats heated or not), so basically you will do a mix of the 2 codings. My actual coding is 369100B824 (3.0TDI V6, sedan, with parking heater, with rear seat heating, no sunroof.....)
Last but not least, the door modules need coding, here the bits are not documented so we are in the blind, but I found the coding from a similar car with both memory modules and compared the coding:
Address 42: Door Elect, Driver (J386) Labels: None
new Coding: 011F1E215E00628202080013
old Coding: 011F1E015E00628002080013
Address 52: Door Elect, Pass. (J387) Labels: None
new Coding: 011F1E215E00628202080002
old Coding: 011F1E015E00628002080002
Only the 2 highlighted bytes from each module were changed.

So this is all, a few pictures with the interior and the car [:D]

[durfA4]

I have them in the car.

I installed the correct control module from the A8, I haven’t added the power wire so I have low current code and nothing in the MMI. Yet.

I have everything to do it, but it is cold and I got side tracked picking up this https://uploads.tapatalk-cdn.com/20171230/7372bef4e9c9624515ce141b2a4cd77d.jpg

I have the hardware and contact to remove the component protection. I needed to get a special software and obd2 dongle so I can skype with the guy in Poland to access the Audi database.

The seats look much nicer than the base seats and for the price I won the for was amazing. I will get them programmed once I want to go out in the cold.

Yeah the B5 is nice. Needs cleaning and details. Like all B5s it needs a bumper. I had to zip tie this to get home. Came with a RiegerRS4 bumper separately. I’ll need to get it glued and squared up then drop it off at the body shop.

I have koni coil overs, 18z, and a few more mods for it. Slowly but I’ll make it super clean. Good canvas to start with so it’ll come together

I managed to find a pair of a8 comfort seats for $500 shipped for the both of them, so I figured I’d give it a shot. Hopefully they’re in decent condition as the pics of them really sucked. Would you be willing to share the info of your contact to remove the CP?

Thank you for sharing everything so far.

[durfA4]

I haven’t finished adding the power wiring for mine yet. But I would first swap the seat control modules from your seats into the A8 seats. then go through vag com and try to get coding correct.

The module will definitely work for moving the seat. And most likely it should function fully.

But if you need the component protection removed I can message you the contact info. I only chatted with him once, and I haven’t had the time to make it work yet.

I just bought a 2018 S6, and the seats are not only fantastic looking, but very comfortable as well. I just can't get past the looks of the 'comfort' ones; they belong on a Buick, especially with the awesome flat-bottom wheel and C/F trim. I'd have preferred ventilation, yes (all my other cars have it), but not at the cost of the seats looking like that. And the leather also looks and feels super crappy, as it's not nearly the quality of the Valcona on the sport seats my car has. I also tried them, and as somebody said earlier on the thread, the ventilation really sucks, so I lost interest in those seats. The massage sounded nice for my wife, but never had it, and again, wouldn't sacrifice the sport seats just for that. My question for the masses is if there's anything different on the seats other than the plumbing and crap to make them ventilated and with massage. Haven't gone on a trip on my car, but hope the seats are comfortable enough. They surely feel that way now. Sat on the RS3 and TTS, and they felt much firmer on the butt, probably making them uncomfortable after hours. Mine feel better. Other than maybe not fitting 'larger' folks, I felt the comfort seats are not any more comfortable than mine, but that was only from a relatively short test drive. I also liked the support of the sport seats way better, but I'm a thin guy.

I also liked the support of the sport seats way better, but I'm a thin guy.

TL,DR: I like the comfort seats better. Just bought my A6 to replace a comfy Volvo with massage seats, and want the same function in my Audi.


I personally find the comfort seats to be much more appealing in appearance than the sport S6 seats. I’m not a fan of the integrated headrest in a luxury car. My Maserati has that sort of seat and I’m not really even a fan of it in that car. I’m, as you described, a “larger” folk. I’m 6’3” 250lbs. The Recaro sport seats in my S8 are pushing it for me as far as narrowness, and my A6 is assuming daily driver responsibility from my Volvo S80 which I’ve just retired after 320k trouble-free miles of comfort. My Volvo had Heated/Ventilated/Massage Seats, and those are all features to which I’ve grown accustomed. My A6 is of the Prestige trim level, so it already has the comfort seat option with ventilation, however they don’t have massage, and the A8 seats offer a lot more adjustment.

I do agree that the feel of the standard leather really sucks. It also has virtually no leather smell as far as I can tell. My S80 with the sovereign hide leather had an interior which felt and smelled amazing even after all those miles. In fact, I believe the leather quality is my biggest gripe about the Audi, especially given their reputation for interior materials. The silk Napa leather in my S8 is wonderful stuff too. Thinking back to my C5 A6, even that had, very nice, soft leather. Volvo just started doing the same thing on their lower trim level cars. They’re using a cheaper feeling leather.

PS- sorry about all the Volvo comparisons. I always drove a6s as my daily cars. I had a 95.5 S6 Avant, then a 99 A6 Avant, then an 01 A6 4.2. Then I moved to the Volvo S80 V8 in 2008 because the car was nearly $15k off with incentives due to the financial crisis. It turned out being the best car I’ve ever owned, but I decided to retire it after 320k miles. I decided to go back to my roots with the ‘13 A6 as volvo doesn’t have a car with comparable tech that can be purchased on the used market for anywhere near the same price. Over the years, I’ve become a mod on the biggest Volvo forum, and of course everybody there is outraged that I went to the “dark side”. I know I’ll be happy with the A6 once I finish adding the features i lost by switching. All I have left are the massage seats. :D

I am not sure you will have to run power, you already have the comfort seats. I did a fair amount of research and found out that as far as i can tell all newer Audi’s seats are mostly interchangeable but pattern.
C7 options
1. std seats
2. Comfort
3. Multi contour + masssage A8
4. Sport seats
5. RS sport seats

I believe you may be able swap control units and plug and play. Just depends if you have the green connector or not.

Based on pics of other a6 comfort seats, I do believe I have the green connector. I think I also have the can wires though to activate the ventilation.

If I have the green connector, what wiring must be changed? Just the power to pin 17?

I installed the seats today. I discovered some interesting things. There aren’t actual modules on the a6 seats like the ones on the a8 seats.

The passenger side has the green connector and is missing the power to pin 17 in the red connector, as well as the canbus to the red connector. With the seat plugged in, all of the normal power functions work, but the multicontour, massage, heat, and ventilation do not work.

The drivers seat is where things get interesting. My car did NOT have the green connector on the drivers side. With the new seat connected, the normal power functions work AND the heat and ventilation work. The red connector is still missing pin 17 power and the canbus wires.

I plan on installing the necessary wires next week and will report back.

Does anyone have any thoughts as to why the heat and ventilation work on the drivers side without the green plug but won’t work on the passenger side with the green plug?

Some observations about the difference between the seats. The a8 seats sit a bit higher than the a6 seats. They’re also more firm. The heated seats seem hotter and the ventilation is quieter and definitely more powerful in the a8 seats. The a6 seat ventilation was disappointing.

I’m also getting an airbag light and a code for the seat occupancy sensor in the passenger seat not being properly configured. Any idea here?

Another note, I called the Audi dealer for an estimate on removing component protection once I get the wiring done. They put the lead tech on the phone who absolutely insisted that there is no cp on seats and if I have issues, it’s something else. They wouldn’t give me an estimate since they said what I was asking for wasn’t possible. Unfortunately, the next closest Audi dealer is 100 miles away, so I’ll have to try to find another avenue for removing the cp.

Here are some pics showing the a8 seat on the passenger side and the original a6 comfort seat on the driver side.

I have the tool and contact information to remove component protection. I just haven’t gotten that far. Yet.

I have the air bag light for passenger seat sensor. I feel that is related to can bus wires since the factory sensor is direct wired. I am waiting for the cp removal to deal with that. Also I am aware of another situation going from comfort to euro sport seats that have the light on as well.

Interesting about the seat ventilation.

Also there is some coding to the door modules. The passenger memory seats and all the other things.

The wiring should be straight forward.

Hi there,

Hopefully someone will be able to answer my question. Looking to retrofit A8 comfort seats with ventilation and massage (2014) into my Audi A7 (also 2014). The A7 currently has standard seats but already has memory, ventilation, and heating. Is the required rewiring other users have been referring to on this forum expected to be as involved for this specific swap? Or, should the retrofit be closer to plug and play so long as component protection is removed and seats are correctly coded with MMI?

Cheers

If y'all have good condition seats and got rid of them for comfort seats, I'd be willing to buy if you're not looking for an arm and a leg. EBay is the safest bet for both the seller and buyer. PM me if you got a set :D pictures would be helpful

[FirstAudiA6]

Hey all, I've landed here because the base seats in the A6 are terrible. I've got a 2016 A6 3.0 I picked up in January and am struggling to find comfort in the seat. I would like to swap out for the Contour Seats...I've read the entire thread but was hoping for just a little guidance. I've got black lthr, heating, lumbar, and memory now. Since the comfort seating was an option on my model (although its next to impossible to find one that has it stock) I'm hoping the swap is a little bit more plug-n-play..or will I need to modify the wiring harness?
I know I won't get ventilation since I don't have the right climatic panel but can I assume all other functions should work?
Any advice greatly appreciated.

[si74]

I can't speak for the more experienced members but I've had a hard time with the retrofit. Purchased A8 multicontour seats with massage and ventilation. Already had heating and ventilation in my A7 seats (2014). Had a local shop rewire the harnesses as per official wiring diagrams. I did not switch out the A7 seating modules from my original seats into the new ones (don't even know if this can be done between different model seats). Went to dealer who was willing to attempt to remove CP and was partially successful on driver side:

What worked:

- driver heating
- driver ventilation
- driver memory

What didn't work:

- multicontour module not detected (passenger and driver); no multicontour or massage functions available
- ventilation module not detected (passenger); heating and ventilation functions not work
- airbag sensor not detected (passenger)

This was after VCDS coding was done to select multicontour seats in the CAN Gateway and deselect seat heating in the central electrics.

I had hoped that there would be cross-compatibility between the A8 and A7. Doesn't seem to be the case. I'm somewhat torn as the seats (even with limited functionality) are MUCH more comfortable, but I did have my hopes up for the additional functions. I'm also not comfortable with the idea of the airbag sensor not worker on the passenger side.

[BenMTL]

Hey guys, hopefully a quick question and hope somebody knows....

So my car is LHD (regular), but I found exactly the kind of seats I want to swap to but they are from a RHD car (from UK).

Should LHD and RHD front seats be the same? Both are leather, sline, etc just his are fully powered and mine are manual.

Any problem having his driver seat being my passenger seat, and his passenger seat being my drivers seat you think?

[morski]

Yes, there will be the air bag sensor in the passenger seat which will end up being the drivers seat and hence will be missing from the passenger seat. Also depends if they are both memory or just drivers seat?
Ive done this before and it can be done, but only if you are willing to remove leather covers and fit a new sensor mat

[BenMTL]

Interesting...Other than transferring the bladder, everything else should just hook up correctly? Neither cars have memory seats option [:D]

After removing the leather covers, does anything need to be sewed up again or is it easily removeable like on my B7? And by "sensor mat" you mean the occupancy sensor (bladder) right?

[morski]

Yes the sensor mat, needs swapping over or a new one fitting. Easily damaged hence why the repair manual only allows a fitment of a new one. Not sure what the B7 leather is like but you need hog rings and pliers to cut the old ones and fit new ones to keep the leather in situ

So, I seem to be having a conversation with myself about the A8 retrofit but I figured I'd share what I've learned anyways as there were a few other members attempting the same thing.

The pneumatics mechanism and multicontour modules appear to be identical parts in the A8 and the A7 (as suggested by the part identification numbers). However, the seat control module is different between the A8 (4H0959850) and the A7 (4G8959760). There seem to be three variants of the A7 control module - A, B, and C. 4G8959760A is for non-comfort seats. 4G8959760B is for comfort seats without ventilation. 4G8959760C is for comfort seats with ventilation - so this seems to be the one. My current best guess is that swapping out the correct A7 control module for the A8 one will fix the communication problems with the seat.

Hope this helps somewhat. Am debating as to whether I will attempt. Good luck to the others.

Cheers.

Anyone have any idea on how much the A6 contour seat swap to a A6 with base seats. 2016

Alright, was able to pull out my seats from a flooded car.

The RED connector on the car ONLY has 4 connectors, the A8 seat has 15 wires that need to be connected. Am I able to follow the connector on the car and replace it so it can connect all of them or am I screwed?

I'm also missing the green connector on the comfort seats, but expected as people were saying it was for heating.

EDIT: Cleaned up the plugs on the car, put in the A8 seat in. Still no power to the seat and now I'm getting an airbag light on the dash.

[si74]

For those of you who have been attempting the A8 seat retrofit, do you know if the connections into the A7 control module (J136) are identical to the A8? I'm not talking about the couplers underneath the seat that connect to the central electrics etc., but the connections from the various seat components going into the seat control module itself. Is rewiring/repinning of the connectors required to do a swap?

[durfA4]

I am using A8 control modules. And swapped my A7 one in. So I know the plugs are the same.

I lost the contact I had for component protection removal. He is in Poland on Skype. I found him by google and he replied quick.

I have one seat installed and haven’t gotten anything further because I bought a B5 and have been spending free time on that.

Thanks durfA4. There are (i think) 6 extra wires on the A8's 17-pin coupling connector as compared to the A7 comfort seat configuration. Does anyone know what these wires are for? I only have the A7 service manual.

Hey durfa4, how much did the guy charge you for CP removal and what tools did you need before hand? Also, did the car recognize the seat before CP removal or did you get CP removed before putting the seat in? Thanks

[durfA4]

I haven’t tried removing the CP yet. I have the cable he said I needed, but like I said I got side tracked.

Anyone know where red connector runs in the car? Also where are the fuses for the red connector? I pulled out my seats from a flooded car, seats actually work with a 12v battery, tested the connector on the vehicle, no power on the red connector #16 and #17.

Just a quick question guys...

If my car has no memory seat option....And I buy the seats I want from a car with memory seats....Will they ultimately work?

I don't want memory seats, just powered adjustments (mine are manual adjustment).

It seems all powered 4G seats are also memory?

I think powered seats will work, but no memory. Don't quote me, I'm still looking for a wiring harness that connects my A8 seats to the fuse coupler.

Edit: I would also look under your seats for a red connector then take a picture. You need a ground and the 12v.

[Burnt]

Yeah, not sure if they use the red connector to supply power to air bags, etc or just the yellow connector. My car seats only had memory, the wiring harness was only power to the seats and memory specifically. Found out after I bought decked out seats that I need to swap out the wiring harness to control all the bells and whistles. Which I still don't know if I can do. If you don't have a red connector since you have manual adjusted seats, I'd find out if you can add a red connector to the fuse coupler.

Go through the entire thread and look at your seats before buying decked out seats. Made the mistake on my end of not doing that. Huge headache.

[morski]

Even if you have manual seats you should still have power lumbar which means you will have the bare minimum red connector on a 10A fuse. This can run fully powered seats by upping the fuse to 15A.
Adding memory seats means CP removal CAN wires, New door switch and loom and a couple more cables to install.

Very helpful...Yes I do have power lumber.

OK, so I need to find powered but not memory seats and swap the fuse, easy enough [:)]

Except for the fact the powered seats I have found to date all are memory as well hahha, do powered non-memory 4G seats even exist? [>_<]

[morski]

No, just get the memory seats that you like and plug them in and they will work without errors. If you wire the extra cables in etc and tell the gateway you installed memory seats it will look for it and find CP active!. so.. leave the extra wires, up the fuse and your done.
However comfort seats, ventilated seats are a different ball game and you need wiring CP removal an programming etc

Ventilated seats I don't care for anyway, but by comfort seats you mean the massage function right, or?

Ok great, I can even get seats with memory then, and just not plug those in, lots of options on ebay.de [:)]

[jrp916]

I'd like to offer some advice that I just went thru, for anyone that finds your a6 uncomfortable please make sure you have your seat adjusted correctly. I used to think my wifes pilot was more comfortable, then I realized because her car was so much bigger I would sit up more straight. Now that I've gotten used to an ergonomic seating position I find the stock a6 more comfortable. Also it may take up to a full week to get used to an ergonomic seat position at first it make not feel right, but try it for at least a week.

Here is a great video on the topic-

Tes, massaging comfort seats. What seats do you have at the moment? S line seats with manual adjustment and power lumbar?

[giggioaudi]

Hi Guys, you ask for help ....
I retrofitted the Audi A4 8W 2016 electric seats with memory (driver side) with massage function. I made the connections of the red connector, following the scheme of the Audi Q7 4M (in the Audi A4 8W there is nothing for what concerns the massage function). There is no CP in the new memory unit. I connected Can L / H and Lin, I brought another feeding for the massage function. Currently I have working electric seats, working memories, but multicomponent commands do not respond. What should I do?

[si74]

So, it's been 8 long months but finally completed the retrofit!!!! Gave up on retrofitting A8 seats and sold them off to a guy who wanted them for his boat (go figure!!). Picked up a set of comfort seats from a 2015 A7. After a lot of wiring troubleshooting took them to the dealer today for CP removal. Heating, ventilation, and multicontour functions were working without CP removal - only the massage function was restricted.

After CP removal everything (including massage) is working perfectly!!! Last tweak was to increase the intensity of the massage settings through VCDS. A lot of grief but worth the effort in the end!! [:D][:D][:D]

Holy crap, what a journey. I'm in the process of retrofitting A8 seats into my A7, it is a total mess. I'm tempted to do what you are doing, but I don't know where I can sell my seats. Going to the dealer ship to get some fluids topped off and I'll see if I can buy a wiring harness for an A8 to fit into an A7.

[vinlan]

I haven’t finished adding the power wiring for mine yet. But I would first swap the seat control modules from your seats into the A8 seats. then go through vag com and try to get coding correct.

The module will definitely work for moving the seat. And most likely it should function fully.

But if you need the component protection removed I can message you the contact info. I only chatted with him once, and I haven’t had the time to make it work yet.

These are the features that won't work when the component protection is on, even if you try to do it blind. After you get the CP removed and add the coding, it will start to work ;)

can you please share the vcds coding for massage intensity ?

[si74]

Hi vinian. Yes. You need an active CANBUS connection for heating, ventilation, and bolster functions to work with the multicontour seats.

[si74]

can you please share the vcds coding for massage intensity ?

Module 88 (Multicont. Seat Driver) -> Adaptation -> drop down box select the option “Intensity level 1 of massage function”. Enter a new value. Repeat for Intensity levels 2 through 5. You can go all the way up to "100" intensity. I believe I used 90 for level 5, 80 for level 4, 70 for level 3, and so on.

The massage function is a little noisier at higher intensities (i.e., you can hear the bladders inflate/deflate) but that's not a major concern for me.

Hello All, still trying to retrofit A8 seats into my A7. I've got 3 pins on my A7 seats, and 15 pins on the A8 seats. I need to find the wiring harness that connects to the seat to the fuse coupling station under the A-pillar. The A8 seats have heating, memory, and message.

Talked with the Audi service guy, he wanted me to find the part number for the wiring harness because both of us went cross-eyed looking at the schematics. Looking at the schematics below, I need to connect #10 to the appropriate wires. I've got the connector, which the schematic shows, but not the wires. Do I have to manually connect each wire to the appropriate area? I'm now getting the feeling they will only supply me the connector and I have to manually wire each one.

The goal was to give the passenger electronic seat functions. When hooking everything up I didn't need to change any connectors or pins, just add a missing fuse. The harness that was from factory was able to support it. Looks like they are making it harder for us modders.

Ciao!

It’s been already a couple of years since I’ve finished interior retrofit project. At that point, I left out memory function for passenger side. Recently I found the memory button and the door panel trim for it at affordable price. Decided to throw those in, as everything was practically ready for it.

What I did to complete this was:
- Connected memory wire to pin 5 in A-pilar door feed through connector (it was already wired to there just in case, but not connected)
- Connected memory button
- VCDS: ticked passenger memory module as installed from 19-CAN Gateway installation list. Fixed coding in 52-Door Elect, Pass: Byte 4, bit = 1

For my understanding that should do the trick, but unfortunately memory does not work. When you try pressing whatever button, it just shows “seat memory locked” on the screen. Also occasionally “press on/off to set(or adjust)??”. Light on "OFF" button does not lit. Button unit is however working, tried it on drivers side.

Tried also playing around with VCDS. Noticed under door control module that there was “memory button” under advanced measuring values. When ticking this on, on driver side it shows binary “0 0 0 0 0”, which then start to change “1” when pushing the memory buttons. On passenger side, instead of binary it shows “not installed”

What am I missing, any ideas? Was there some wiring that needed to be done inside door panel?

I just installed 2013 A8 multicontour diamond stitched seats into my 2012 A6. I wired 12V into terminal 17 and got the multicontour to work, until it stopped. Same thing with memory. I suspect it's because of the CP but don't know who can help me with CP removal.


Can anyone here help me with getting CP removed on my modules?

Thanks.

You need the factory scan tool to do that.

[morski]

@p3u Does your scan show CP in the module or gateway for the new passenger seat you installed? Reason being the drivers memory module has the CP and functions are limited until its removed

I'm getting back into getting my A8 seats coded into my A7. I just got the day subscription of Erwin. Does anyone know where the wiring diagram is?


Starting from the beginning again. Bought A8 seats, they are currently in the A7, but no power to them. The red plug with all the controls are much more complicated on the A8 seats. A7 seats had 4 wires coming out of the red plug, the A8 seats have 15 prongs out of the red.

Do I have to make new wires from the seat > A pillar > other areas of the car (MMI, relays, etc)? Or do I just need new wires from the seats to A pillar (A pillar is connected to all the computers and relays by default)?

I have the a6/s6 stuff... if you need any of it let me know.

[vrod]

Ok so I am doing the retrofit now and just wanted to chime in with my notes so far:

I have a facelift S6, that model has electrical front seats with memory on driverside as standard.

In my case I have the black, red, green connector.

The red connector is for the power adjustment like front/back, lumbar and all that stuff. Included is also footwell lights for the rear.
The black connector has the cables for the seat buckle detection as well as a seat sensor for the passenger side.
The green connector is solely for seat heating. You got the heating elements but also temperature sensors.

The A8 comfort seats have no green connector because their seat heating is controlled by the seat module (J800). I have decided to just leave the green connector as it is, no need to rewire anything there.

I have only done drivers seat so far, here in europe itÂ’s not allowed to sell used seats with airbags or belt buckles so I had to take out the airbag from the old seat and put it in the new one. Fits perfectly. Buckle as well. I have no errors on the airbags so far.

The footwell LED in the A8 seats have a 4 pin connector vs the 2 pin connector in A6. On closer inspection, it looks like thereÂ’s 2 LED diodes in the A8 whereas the A6 has 1 LED diode. Leaving it as it is makes the LED shine white light. Matches my current ambient lighting perfectly.

My electrical adjustments work as expected. The lumbar support is not working right now because itÂ’s controlled by the multicontour control module which does not yet have power. For this, you need to wire Pin 17 on the red connector to a fuse. After that I will need to fix the component protection but then it should work, might need some coding tho.

Some things to note is that the headrest has an active safety function (basically shoots part of itself out to stabilize your head in a crash). This means there is a pair of wires in the red plug for that. Whether itÂ’s possible to use this feature is unknown for me at this point, but my airbag control module is a 4H0 module.

Additionally thereÂ’s a pair of wires for the electrical adjustment of the safety belt which is not found on the A6 or A7.

For the passenger side I believe I need to pull a wire for the memory function. Will post a copy of my wiring comparison I did earlier today.

[vrod]

So as promised, here the picture. This is for the drivers side but should be almost identical on the passenger side. I live in Germany so it's LHD.

https://sky.vrod.dk/apps/files_sharing/publicpreview/y4KoLwYjrigjTaq?x=1920&y=616&a=true&file=Driver-side-wiring.PNG&scalingup=0

I hope it helps someone. Should be valid for the A6 contour seats too.

[nthusiastt]

vrod, I saw it but looks like it's disappeared. Can you share again? Also, with this diagram if I straight wire it by what you've described, what functionality do I retain with the a8 seat?

Headrest?
Lumbar?
Back and base adjustments?
Heat?
Vent?
Massage?

[vrod]

@nthusiastt - funny enough, I can only see this picture on my phone in the post, not on the PC..

I think this should work:

https://sky.vrod.dk/s/y4KoLwYjrigjTaq/preview

Back to your question, if you have memory in the seat you are replacing, you are missing a single power wire for the multicontour control module (massage, lumbar support). If you only have electrical adjustment without memory, you are also missing 2 canbus wires and a single wire to the door control panel in the respective side (for the memory buttons).

You will retain all functions, at least I did. However, you need component protection removed for the memory controller as well as the climate control panel that will be installed for the seat ventilation. This control panel is 1000€ almost at audi but I scooped a new one up in the neighbourhood for 450 bucks from a guy who gave up on his project. For all my retrofit projects I have a mate remove the component protection for the modules remotely, if you want his details, shoot a PM.

However, to update my own progress, the retrofit is almost complete. I had the drivers seat working for a week (the massage is VERY nice) before I continued on putting in the passenger seat. The menu on the MMI will not show up with only one seat installed, you need both installed.

Since airbags is a rather sensitive topic, I won't go much into detail about that, other than that you can re-use the existing ones, they fit right on. As always with airbags, be CAREFUL!

Since the drivers seat originally had memory, I only had to wire a single power line to that seat. However, because my passenger seat did now, I had to wire a pair of canbus wires and a single wire to the door in addition to the power line. One thing to note about the power line in the passenger side is that the fuse diagram in elsawin did not match with the fuses in my car. I ended up choosing a random fuse location and then installed the cable there. works as well as any :) For both sides, the fuse is supposed to be 7.5A. The power is for the muticontour control module (air compressor in the back of the seat). The seat heating and memory module gets power from the original power wire.

The canbus wires takes a little while to pull, since the canbus-distributor is on the drivers side. I ended up pulling the wires behind the glovebox, MMI and cluster. You will need to take out the glovebox, center speaker trim and cluster in order to get behind there.. The blue wire is canbus, red is power, green is for the door

Glovebox:

https://sky.vrod.dk/s/ybgKx656SXj3Rfa/preview

Cluster:
https://sky.vrod.dk/s/mz5twiD9wYWRLFE/preview

Crimped on the connectors and plugged it into the canbus distributor. It can look overwhelming at first and the contact housing itself is very annoying to work with. Remember to use twisted cables for canbus and remember to ensure that you don't choose a random location for the pins as they are grouped. I did it wrong and chose to use the easiest accessible ones, resulted in no communication to module. You can see the tiny spaces between the pin groups, I was supposed to have wired it to the group in the "top" of the plug, but had wired it to the bottom:

https://sky.vrod.dk/s/cyFiRD9errNpY9P/preview

For the climate control panel, you need to make sure that you get the right revision. Due to some electronical differences between Pre-facelift and facelift, there are different revisions. I got a "CE" revision as mine is a facelift, I believe "P" is pre-facelift. I recommend putting this in only when both seats are in and you have communication to their modules so you can get the component protection done in one go.

Coding-wise, so far I haven't needed to do anything on the seat modules. Only coding I did was to update the installation list in my gateway and "transfer" the coding from my old climate control panel to the new one. In addition to this, you need to check the boxes for seat ventilation in long coding. After doing this I had no errors in my climate control panel. I also do not have any errors in the seat modules.

Only thing left for me right now is to wire the passenger seat module to its door, as I so far have not done any door wiring. I am currently waiting on the "female" terminal pins that I can crimp onto the wire for the door module.

The 2 seats installed, they will get some nice leather treatment :)

I will attempt to compose somekind of "manual" later on when I am completely done. Will for sure update with the next steps when I get to it :)

Hello everyone!
This is my first post here on Audizine :)
Last month I have retrofitted Comfort seats from A7 to my 2012 A6. Everything is working, but since I didn`t install memory buttons for passenger seats, I am getting a message on MMI screen, that passenger memory function is blocked. How can I get rid of that warning without installing memory buttons? I will install them at later stage though - all of the wiring is done, but I need different wood trim for that.
I also have one fault on the passenger seat although it works fine. Maybe some kind of adaptation has to be done to it?
Last, but not least - in 88 and 89 blocks, part number for the front seats is for A8 seats, but mine are from A7 100% - how is that possible?

@nthusiastt - funny enough, I can only see this picture on my phone in the post, not on the PC..

I think this should work:



Back to your question, if you have memory in the seat you are replacing, you are missing a single power wire for the multicontour control module (massage, lumbar support). If you only have electrical adjustment without memory, you are also missing 2 canbus wires and a single wire to the door control panel in the respective side (for the memory buttons).

You will retain all functions, at least I did. However, you need component protection removed for the memory controller as well as the climate control panel that will be installed for the seat ventilation. This control panel is 1000€ almost at audi but I scooped a new one up in the neighbourhood for 450 bucks from a guy who gave up on his project. For all my retrofit projects I have a mate remove the component protection for the modules remotely, if you want his details, shoot a PM.

However, to update my own progress, the retrofit is almost complete. I had the drivers seat working for a week (the massage is VERY nice) before I continued on putting in the passenger seat. The menu on the MMI will not show up with only one seat installed, you need both installed.

Since airbags is a rather sensitive topic, I won't go much into detail about that, other than that you can re-use the existing ones, they fit right on. As always with airbags, be CAREFUL!

Since the drivers seat originally had memory, I only had to wire a single power line to that seat. However, because my passenger seat did now, I had to wire a pair of canbus wires and a single wire to the door in addition to the power line. One thing to note about the power line in the passenger side is that the fuse diagram in elsawin did not match with the fuses in my car. I ended up choosing a random fuse location and then installed the cable there. works as well as any :) For both sides, the fuse is supposed to be 7.5A. The power is for the muticontour control module (air compressor in the back of the seat). The seat heating and memory module gets power from the original power wire.

The canbus wires takes a little while to pull, since the canbus-distributor is on the drivers side. I ended up pulling the wires behind the glovebox, MMI and cluster. You will need to take out the glovebox, center speaker trim and cluster in order to get behind there.. The blue wire is canbus, red is power, green is for the door


For the climate control panel, you need to make sure that you get the right revision. Due to some electronical differences between Pre-facelift and facelift, there are different revisions. I got a "CE" revision as mine is a facelift, I believe "P" is pre-facelift. I recommend putting this in only when both seats are in and you have communication to their modules so you can get the component protection done in one go.

Coding-wise, so far I haven't needed to do anything on the seat modules. Only coding I did was to update the installation list in my gateway and "transfer" the coding from my old climate control panel to the new one. In addition to this, you need to check the boxes for seat ventilation in long coding. After doing this I had no errors in my climate control panel. I also do not have any errors in the seat modules.

Only thing left for me right now is to wire the passenger seat module to its door, as I so far have not done any door wiring. I am currently waiting on the "female" terminal pins that I can crimp onto the wire for the door module.

The 2 seats installed, they will get some nice leather treatment :)



I will attempt to compose somekind of "manual" later on when I am completely done. Will for sure update with the next steps when I get to it :)

I threw out the idea of installing A8 seats after reading numerous (failed) attempts making them to work in other bodies than A8. Problem is in the controller communication - 4G is CAN, 4H is CAN and LIN. All of the functions will not work. I saw them working only on first gen Q7. Even then the owner was a tech wizard with some serious equipment.

[vrod]

What do you mean by all functions? I have heating, ventilation, lumbar, massage, headrest adjustment, memory, etc. Only thing I do not have is the electrically adjustable seat belt, as this was never made for the A6/7.

I have many modules in my car already that are used in the A8, my airbag control module for example. This light even make it possible to utilize the active headrests. But that’s for a later time.

I believe it depends on the coding and modules that are used in the process. My seats was from either one of the last pre-facelift A8 or a very early facelift A8, since several of the parts from them are made in 2012/2013.

Problem with VAG is that all retrofits are very individual. They are not straightforward and if you did it successfully on one car, it does not mean it will work on another car. Just like with mine seats - it was nothing like anything mentioned in this topic. Adjustments had to be made in green menu before they started functioning even after CP was removed.
Long story short - you are lucky that your A8 seats are fully functioning now :)

[vrod]

It reminds me with a golf 6 steering wheel retrofit that i did in my golf 5 back then. You needed a specific version of the slipring and cc stalk, otherwise you would have issues.

As mentioned, mine is a facelift which uses MIB2, the pre-facelift uses RMC. There certainly are electrical differences. I hope though that my documentation can help others.

[bmgante]

Hello, I’ve been reading carefully this interesting thread but while everyone seems to be interested in retrofitting confort/contour seats on A6/A7 I am more interested in the opposite :)

I have an Audi A7 facelift 2015 with contour seats (heated, memory on drivers and passenger sides, mmi integration, no ventilated, no massage) and would like to swap them by the Recaro super sport seats (electric, memory, heated).

Does anyone know if this is a direct swap and how to deal with existing contour seats mmi integration that does not apply to super sport seats? Has anyone changed from contour seats to fully electric sport/super sport seats?

Thanks in advance

[fit]

Before getting the CP removed, you should check if everything has been connected correctly. To do this, you must use VCDS to check that you can find 4 new modules (2x comfort + 2x memory) connected in the CAN bus. If these are not found, then you should re-check the wiring.

Component protection only prevents memory function to work and comfort settings to appear. Seats should still move and tillt, and the heating should work too.

Guys, this is the only thread in the world about retrofitting multi contour AUDI seats - I hope someone is looking at this thread
I installed multi contour seats in Q7 (I had electric with heating as standard) - now the driver's seat is adjustable for lumbar support and basic movement - but no MMI support for bolstering
as I understand it - I will not see the comfort modules in the gate without wiring? then after removing the CP should be visible in MMI?

Hello all. So I am reviving this topic with an issue that I cannot solve for now. I have and Audi A6 Avant 2013 with the textile sport seats with manual adjustments and electrical lumbar support. I bought some ventilated comfort seats from an Audi S7. All the extra wires were added, ventilation, heating and massage are all working including the MMI pop up. The front and rear climatronics were also changed from the S7. All is working normally.

The only issue that I have is related to an error on the front passenger seat occupant sensor. I tried to code the airbag module but I get an error each time. Also running the basic settings is not working. The error that I get is: B102715 Front passenger seat occupant sensor. Open circuit/short circuit to B+. I also discovered that the seats from the S7 may be from the US market and my car is for the European one. Also what is strange is that even if I buckle both seatbelts, the seatbelt light is still on in the dashboard. Like it doesn't recognizes that the seatbelts are plugged.

So maybe as solutions to my problem:
1. Replace the seat occupancy sensor with the old one from the textile seats.
2. Try to change the airbag module with the one from the S7. The only issue is that the S7 doesn't have the rear bolster airbags, so I may run into a different error, as I have the 2 extra airbags in the rear.

Any suggestions or ideas? :)

[TheBlackMarvel]

There is a recall of the passenger occupancy detector on comfort seats. If you have the donor vin you can check to see if eligible. I had to have it replaced under recall on mine as it was throwing an error code as well.

I had the seatbelt issue going the other way... Euro Seats into us model. The fix is to swap back the seat belt receivers from your car.
The PODS is an altogether different issue.

I'm pretty sure it is, but I can't be completely sure.

I may play around with VCDS and see if there is coding in there for comfort seats that can be activated.

Reviving this old thread - Has this been done? I found a donor car with the comfort seat from a prestige S7 that I'd like to swap in my A7. the lack of lumbar in the passenger seat is a real challenge for my g/f on long trips.

Thanks!

I dunno if a retrofit is possible or not... but I have the comfort seating package from factory in my 2016 A6. So if you need some coding for reference just tell me what you need. I have vcds and OBD11.

So my seatbelt issue was solved by using the old seatbelts. It seemed strange for me as I thought that the seatbelts have just an on/off button inside :)

Now the seat passenger presence sensor error still shows up. I tried to use the one from the old seats, but it is a completely different sensor, old one has 2 wires connected to the sensor, the one from the comfort seats is a coax cable. The good parts is that I found a new one with ~50 euro. So probably I will order it and try to replace it. Even though it is a pain in the ass to untrim the leather cover from the seat.

This has me wondering if d4 a8 seats will for a d3 a8 front and rear..... i appreciate the information on this forum

[Teemu_H]

Hi,

For first my english is not good. I have 2012 A6 with comfort seats (massage, ventilated etc.). In factory this car has no electric seats, and someone is retrofitted comfort seats and do wirings. The problem is that massage, ventilation, lumbar and side support-pneumatics not working, so only heating (i put driver seat heating "on" and passenger seat heating too[o_o]), move up/down, front/back and tilt work.

I took car to audi and CP removing is done, doesn't error this anymore. I only want massage, lumbar and side support-pneumatics working. Massage and side supports work with vcds output test, so why they dont work seat buttons? And just information that there is no memory buttons doors and MMI is 3G+.

I hope that someone understood my bad english and what is wrong with these seats or maybe wirings?

Hi guys, I have read the entire thread but I am going crazy with the number of different things I have read, and it is not clear to me what cables I need etc. I have heated electric seats with memory and my steering wheel is also heated with memory, I would like install some comfort seats with heating and memory, in short with the same characteristics as the ones I already have but with lateral adjustment (comfort) could someone tell me how many cables I have to pull from which point to which point? I would be very grateful, in principle having a memory in the passenger seat doesn't matter to me because people hardly ride and when someone rides they can adjust it to their liking. Thanks in advance

[Audi-Hogger]

A lot of good information here in the thread albeit a little sidetracked with the a8 into c7 retrofit.
I just received some c7 comfort seats I want to install in my c7 a6 prestige.
Is removal of Component Protection required? If so, is this a DIY or a dealer issue? TIA

[fedotenkoi]

Hi all! I replaced my heated seats with new heated and ventilated seats. The car has a 2-zone automatic climate control. Accordingly, I turned on only the heating. I found out that there are afrermarket LIN adapter. A special unit monitors the temperature outside and, depending on it, sends a command for heating or ventilation via the bus to the reading control unit. Does anyone know where to buy this adapter? Thanks a lot.

[vrod]

Not exactly sure what is being asked here, but in my case i already had heated seats with memory. In order to use ventilation, the control units had to have the CP adapted. I also needed a new climate control unit in order to use the ventilation. I copied the complete coding from my old module, to the new one.

Know that there are different versions, depending on the spec as well as pre-/post-facelift.

Alright I revisited back to this project since I've got some time off. I found out my power to the seats were corroded off the plug where the seats connect into the bottom housing. Anyone know what kind crimp the red 17 pin connectors are? Am I able to pull the old pins out with a pin remover or are they molded in?

Also using this sheet https://imgur.com/ToRCe0c (thank you cuore for making this), I see that #17 on the red connector is power for multicontour. Am I able to use a fuse tap to tap into the "Front passenger seat adjustment thermal fuse" 15A in the A-pillar? Will I need to find a larger fuse (20A?) since #15 is already using it?


Current situation: https://imgur.com/a/zjEDiBe
I have an 2014 Audi A7 TDI that had basic heat and vented seats with 3-button memory on door. Trying to transplant 2010-2017 A8 seats with heat/vent/massage.

The A8 seats has all except two wires connected on the red connector.

[BasicBlack]

Just a hunch, the A8 seats have upper torso (forward / back) controls and headrest height adjustments. The C7 / 7.5 did not have that functionality for comfort seats.

Enjoy the ride.

I just bought 2016 S7 comfort seats to put into my 2014 A6 TDI (US). I test fit the passengers side (with no wiring nor coding changes) but the seat didn’t respond at all. I haven’t tried the drivers but is there a fuse or something that might blow on the seat itself?

Basic functions should be plug and play. I don't know if there any fuses under the seat, but you check all of the fuses for that side? You can also jump the seats with a 12V battery, by connecting leads #15 and #16 on the red connector. I would test the seats if they work if you're unsure and from another car.

[ItsCAvalos]

I put in my regular seat back and it worked perfectly fine without any changes. The seats came out of an accident car. Anyway somehow the modules got fried? The airbags and tensioner didn’t go off in the seats though

[Burnt]

Are you able to take out the modules and swap them with yours to see if they work?

Inspected the power cables? Look at the red connector, 15/16 to see if the wires are intact.

[ItsCAvalos]

Well I tried the drivers seat and the basic functions, including ventilation functioned. Retried the passenger side and nothing. Swapped the modules and the seat moved. Passenger module must be dead because it didn’t work on the drivers side either. Any place that repairs them? Maybe the Audi dealer could reflash it but for $200 I might just get one off eBay. Part number 4g8959760c

I would prob get a new module, but not all functions will work since you'll need component protection off. Basic functions like power, heat, cool will work. If you want massage, etc you'll need component protection off.

I haven't gotten far enough to seek out people who know how to get it removed. Reading forums, you likely need a factory scan tool, but I've seen people do it at home? Maybe they have a factory scan tool @ home?

[ItsCAvalos]

I went to the dealer for my B8 and they charged me $180? I’ll probably do the same for this so they can remove CP off my new (used) night vision camera, seats, and maybe my power close trunk retrofit if that needs it. Either way this will take some time for me since I don’t have any of the materials to 100% do this retrofit for the seats.

Let me know how much they charge you. I was gonna call them up and then call up an indie shop.

Hi everyone!
Got myself a set of comfort seats. It does not have the green connectors. Is it possible to not having the heating funtions?
It has the black the red and yellow for airbag.
Thanks in advance

[frantic77]

I didn't mention it clearly has seat ventilation too. Really strange not having heat funktion....

[frantic77]

My car had CP removed yesterday and popup menu works now. Only thing I did, was that I selected that bit 7 on byte 6, in module 5F. Please note that, this is for MMI low only. If you have that high resolution 7” screen, then the coding is different quite sure. At least the coding is many bytes longer.

It is possible that the Communication Disruption fault code might have been due to wrong coding as well. Popilam seemed to have it too earlier, even though he did not have CP active. I dont get that any longer, with CP removed and that one bit selected only.

I also bought a HVAC panel with ventilation buttons, and I can tell that those work too. Memory button and panel for drivers side also installed. What still needs to be done, is to connect the wires for the memory under kick panel. Then it should all be there :)

Hi there!
Just got myself a set of comfort seats and have the same problems with the connectors. On comfort seat there is no green connector.
What was the trick to make heating work?
Please give me some advice!
I know it is an old thread but maybe you still remember.
Ps am not interested in memory funtion..
Thanks in advance
