Front Parking Distance Control Retrofit for Facelift 2013 B8.5

[a4huey09]

" I bought a B8 park assist module and moved my rear sensors to that "

Do you have the part number and/or where you purchased the module from?

Thanks!

8K0 919 475 AA is the part # I purchased from carsystems.pl for about 100 EUR shipped to the US (and amazingly came 2 business days after I ordered it). It's also available at your dealer and other typical places for twice that price.

There are many different versions - the AA part is for 8 sensors, graphical support, and rearview camera, and was the newest version of the part when I bought in August. Here's a doc that shows the variety of part numbers, others may work: http://www.scribd.com/doc/105006485/...-Sensor#scribd

One thing to keep in mind is that the 8-sensor system won't function with only 4 sensors plugged into it.

Thanks for the info and the link! I have the back up sensors/camera and want to add the front sensors so I can get the graphical display, which using the part # you ordered should get me there.


Thanks!

One more question, which Kauftec harness did you buy? did you pick up the switch and speaker separately or did you not need to add those?

[meb]

One more question, which Kauftec harness did you buy? did you pick up the switch and speaker separately or did you not need to add those?

For B8.5 I bought:
36318 (front bumper harness)
36315 (trunk to power, CAN, rear speaker)
36316 (trunk to front bumper harness + button + front speaker)
39880 (small harness.. rear bumper sensors to trunk location of parking module)
I also needed to run 1 wire for ignition plus from the driver side to the passenger side.

I would try to buy from the German Kufatec site or at least double check that kufatec's US distributor isn't OEMplus given the less than stellar recent track record.

I picked up the switch (8K2 959 674 G V10 - esp and parking (no sun shade)) from a dealer and speaker (8E0 919 279) off eBay.

Do you have side assist or a sunshade?

Awesome thanks for the list, yes I do have side assist, does that change things? ..And I saw the thread about OEMPlus, but thanks for the heads up on that.

[Elanmike]

Where do you take the harness through the bulkhead in to the engine bay?

edit: This is true if you have a facelift like my car.. not positive how the pre-facelift rear bumper harness is run.

If you have side assist the 39880 harness from kufatec doesn't work as-is (at least the one they sent me, maybe if you contact them ahead of time they can give you the right one). The side assist wiring goes through the same wiring as the parking for rear bumpers, so when you use 39880 to connect the rear bumper harness to the new park distance control in the trunk, you disconnect side assist. I needed to buy part 8E0972416 and patch through the side assist wiring to the main wiring harness in the trunk. I modified 39880 with the 8E0972416 part to create a Y harness, and was able to split PDC to the new module while passing the side assist connections to the normal factory path. I can definitely help out with the schematics and additional wires you need to create one yourself if you you get that far.

There is a pass through on each side of the car that goes through the firewall to the fender area - check out the 3rd picture at the following link: Audi Enthusiasts Hill Hold. The picture shows the diver side, but the passenger side is no different. I removed the glove box and trim pieces around what would be the passenger's right foot, there's a rubber stopper with the factory harness through it. I used a sharp punch to open a path next to the factory wiring and routed the kufatec harness through it (the kufatec harness comes without the connector on one end so you don't need a big hole). On the exterior/fender side I removed the wheel well liner and followed the factory harness to the bumper area.

Ok, wow, that's not as straight fwd as I expected, I plan to give it a go once I get all the parts, appreciate your help, I may ping you once I get started.

Pisses me off that Audi skimped out on this on this level car while including it on lower/lesser models.

Sounds like adding a B8 module is the easiest way then. :)

Which cable did you buy from Kufatec to relocate the module to the trunk?

[meb]

These are US prices. Kufatec in the US seems to take 30+ days, hopefully it's faster to Europe. carsystems.pl also sells kits, you might want to ring them to see what they could provide to fit a B8 module in a B8.5. Here are some notes I had typed up as a start of a DIY (the thought is that this is so involved no one will be interested!):

You can do it two ways - either:

Kufatec kit - 35725-2 - $885

OR:
Kufatec Harnesses & other parts Included in Kit:
36316 – Front sensor harness to rear park distance controller ($56)
39880 – Connect rear park distance controller to rear sensors ($42)
36315 – Central electric harness – button + buzzer + power to rear PDC controller ($42)
36318 – Front bumper sensor harness ($56)
4x 1S0 919 275 Front PDC sensors (eBay) *1
1x 8K0 919 475 AA PDC Module (carsystems.pl) *2
1x 8E0 919 279 Parking Buzzer (for front) (eBay from China $15; dealer/ECS $30)
1x 8K2 959 674 G V10 Button (ESP, Parking) OR 8K2 959 674 J V10 (ESP, Parking, Blind) ~$70

Also needed (unknown if these parts are included in Kufatec kit - I don't think they are):
2x 3C5919491N Left/Right Inner bracket (ECS) *3
2x 3C5919491M Right Outer Bracket (good for both left & right) (ECS) *3
4x 3C0919659 Parking Sensor Washer (ECS)
1x touchup paint for PDC sensors (automotivetouchup.com) *4
1x 8K0907297 PDC module holder (ECS)

Misc odds & ends (ECS):
2x 4L0886373 - rear seat grommet - it's one time use; you need to take the rear seat out (pull up very hard) to run the wiring, this part will get damaged in the process and needs to be replaced
2x 7L6868307 - plastic rivet for parking buzzer
1x 8E0972416 - housing if you have Audi Side Assist - this is needed to modify harness 39880
2x plastic bolt to hold PDC module bracket in (still looking for a part # for this)

*1 - There are many part numbers, these are the same sensors that are used on a ton of German of cars - this is the model I looked for - I got some shipped from Germany for $14 EUR/piece shipped. Other places online have them for $25. From the dealer they're like $100/ea, so I would avoid that!
*2 - I got the PDC module shipped from carsystems.pl for $108EUR. The "AA" at the end is the important part. Search with & without spaces if you have trouble locating Audi parts in a search engine. Dealer/ECS would be around $250.
*3 - these are VW parts - Audi doesn't sell the A4/S4 brackets separate, I am not 100% happy with them but they definitely worked. I chose to use some HomeDepot Plastic Epoxy to glue them on to the bumper after cutting the hole, but I probably would have preferred to use a hot glue gun if I owned one.
*4 - I purchased spray paint & spray clear coat, for about $40 shipped from AutomotiveTouchup.com I did a couple coats of color after sanding the sensor down and a couple coats of clear. You can get your paint code from the PR Code sticker - http://www.audienthusiasts.com/Articles_PRCodes.html

Tools:

• Sockets
• Torx wrenches
• Trim removal tools ($24, Amazon - http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1)
• Radio Removal Tools (Audi Tool # T10057) I got mine for $10 from Amazon - http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
• VAGCOM for coding
• crimper for tyco contacts

To add power (from driver side fuse block to passenger side fuse block), you need 2 of this Tyco contact: 964324-1 and a length of 20awg / .5 mm2 wire
If you have Audi Side Assist, in addition to 8E0972416 you need Tyco contacts: 10x (+spare) 962886-1 and 10x (+spare) 963715-5 and 22 awg / .35 mm2 wire to modify the Kufatec harness (if you get the same one I got - maybe if you ask them they can provide you the correct harness) to pass through the bumper harness to main wiring harness while diverting parking sensors to the trunk parking module.

meb, thank you for taking the time to lay out for others what we need to do to make this happen. Much appreciated.

Much appreciated! So the only items I actually need to order now then is kufatec: 39880, 8K0 919 475 AA and 8K0907297. Everything else I have already bought =)

Glad to help. The module holder isn't strictly necessary, you could probably stick it down with double sided tape. I haven't found the right bolts for it yet anyway.

For 39880: if you have Tyco contacts, crimper, and wire (or a friend at a dealer/source for cheap repair wires), you can make it yourself using the following parts:
8K0 972 416 (connects to bumper harness in right side of trunk behind drop down compartment, takes 962886-1 contacts)
8E0 972 112 (connects to parking module, takes 963715-5 contacts)

If you have side assist, as noted above, you need to add: 8E0 972 112 to pass through those wires to the existing car harness and make a "Y" harness (also takes 963715-5).

The Kufatec one is a bit too short anyway.

[a4huey09]

Meb, thank you for laying this out so clearly. This project has been on my to-do list forever but I wasn't confident enough in what others did or able to decipher what was done/needed to pull the trigger, now I can start accumulating the parts and get this done!!

A big thank you!

Okay. So I have arranged all the cables on the floor before I crack open the car for the retrofit. I'm wondering where some of the cables go.
Please see the attached picture:


Unknown no. 1 = Goes to the control switch in the center console ?





Able to help me out?

[meb]

Okay. So I have arranged all the cables on the floor before I crack open the car for the retrofit. I'm wondering where some of the cables go.
Please see the attached picture:


Unknown no. 1 = Goes to the control switch in the center console ?

Yes, Unknown #1 - goes to control switch in center console. There is an 8 pin connector already in the car. When you replace the button with the new one with the parking aid button, you need to make contact #4 on the 16 pin connector (T16e) that plugs into the parking module go to contact #1 of the button connector (T8r). The other wire is for T16e/13 to go to T8r/3.

The other end of Unknown #1 is Unknown Wire #2 - for some reason Kufatec runs the button and speaker with the front harness rather than CAN + power. So you need to get a multimeter and ring them out, mark them on the button end, plug them into the 16 pin connector, and then run the harnesses to the front.

Ground - the ground is long enough to run to the front, but electrically speaking you should be able to pick up ground anywhere you want. When you're running the front sensors you'll have to remove trim panels right around the passengers right foot. Along the floor there is a ground stud, which is what I used.

Power - I ran the power up to the fuse block on the passenger side to a place where two terminals were empty (I used spot #1 on the left fuse block "ST1" in diagram). Then I ran another power cable from that fuse block to fuse #14 on the left fuse panel on the drivers side ("ST1" on drivers diagram) - this was the only place in the car I could find an open Ignition+ spot.

Unknown #3 - CAN high + low, the data connection between the car network and the parking sensor. On the passenger side fuse areas, there is the CAN Disconnect plug ("A" in diagram) to the right of the two fuse blocks. The two twisted wires go to the 16 pin parking module connector - CAN high goes to T16e/6, CAN low to T16e/15. When you disassemble the CAN disconnect plug (T46s), you can see there are a number of separate CAN buses based on which wires are bussed together. The factory spec connects it to 2H / 2L, but if that is occupied you can plug it into anything that is on the same bus - for example, 6H/6L or 7H/7L.

[edit]:
The last piece is coding - once you connect module 10 and have everything plugged in, you need to use VCDS.
1. CAN Gateway module "Installation List" and let it know you have module 10 connected.
2. Module 09 - Cent Elect - change byte 35 to 00 to disable parking control on that module.
3. Module 6C - update to 1020006 to enable graphical display of parking sensors (YMMV, mine started at 1000006).

Once again.. Much appreciated!
Got the cables sorted out and should be good to go except for one thing.

I'm wondering about the two speaker outputs I've got. 1 on the CAN + PWR harness (speaker connected on the picture) and the other one on the cables for the button in the center console. (labeled front speaker in the picture)

Which one do I use?

Both! For surround sound.

One is for the front speaker for the front sensors, which goes in a very hard to reach place near the drivers right knee (hard to describe, but on the metal support column there are two holes to mount the speaker...between where the drivers knee would be and where the radio is).

The other is for the rear speaker which you already have and is connected currently to your cent elect. It's located under / in the guideway for the the rear passenger side seatbelt. It's not the easiest piece to get out, manual says to remove rear shelf but you may be able to just push it back and to the left to get it out after removing the rear seat and side cushion (and rear seat back if you have a fixed seat?? we don't have that option in North America) (push retaining hook (#4 in image) up, bolt heads slide back and pop out - don't turn the screws). Know what you're doing if you have the side rear airbags!

You disconnect cent elect module and hook it up to your new module. Alternatively leave it hooked in and add a new buzzer somewhere in the same area.

First image is for the driver side, but the buzzer is located on the passenger side and removal is identical.

Of course... Did not think of the other sensors getting re-routed through the new cables

Hi guys,

I am from the Netherlands .
I have an Face-lift Audi A5 Sportback MY2013, you can find all my A5/8T retrofits over here-> http://www.audiforum.nl/forum/audifo...ml#post1518797

And my ex MY2010 A4-8K/B8 over here -> http://www.audiforum.nl/forum/audifo...ml#post1132076



And I am also working on the PDC retrofit, from only rear to PDC plus.

The wiring harnesses from Kufatec quite pricey, € 633.
Would you tipping this Polish provider, which is much cheaper than Kufatec only € 399 -> http://www.carsystems.pl/audi-a4-ava...fit,id729.html

But, I 'm going to make the harnesses completely myself.
Here my Excel parts list to make the harnesses themselves.



Yesterday through the splash plate in the fender looked.
The PDC holder is already present in the front bumper.





In the grill , they are not present. Also look for the VW Passat holders for the grill.



2x 3C5919491N Left/Right Inner bracket (ECS) *3

*3 - these are VW parts -
Audi doesn't sell the A4/S4 brackets separate,
I am not 100% happy with them but they definitely worked.
I chose to use some HomeDepot Plastic Epoxy to glue them on to the bumper after cutting the hole,
but I probably would have preferred to use a hot glue gun if I owned one.

Question, can some one put a detail pictures from the VW Passat holder in this topic ?



Here you will find my PDC retrofit topic on the Dutch Audi forum -> http://www.audiforum.nl/forum/audifo...ml#post1639183

There you find also the official PDC drawings from Audi (ElsaWIN).



Thanks for sharring '' meb '' this intresting topic.

I just, get a better answer, on the Dutch Audiforum

The holders of the S-Line grill from a Audi A5 coupe 3.0 TDi MY2014,
I hope, the are also good, for the face-lift B8,5











8T0 919 267E port side
8T0 919 268E starboard side




Looks better than the VW Passat holders,
I found this pictures from the Passat on eBay.de

Or are you talking about a different kind VW passat holders ?

So I recently completed the parking system upgrade for a B8.5 with the help of meb and just wanted to provide some feedback based upon my install. I ended up buying two sets of harnesses from both carsystems.pl and kufatec. I bought the front upgrade package from carsystems.pl and was overall happy with the hardware components of the kit. I had the company paint the sensors for an extra 30 euros and they came out good. The brackets look like the second set of pictures in Peeet’s post above. They came with double sided tape and stuck quite well.

The harness provided by car systems likely would have worked but in order to make it work on a B8.5 you would need to buy there full 8 sensor kit. The 4 sensor kit did not have a wiring harnesses for the canbus wires, the power, or the rear buzzer that all connect to the 16 pin connector at the trunk terminal. And you would still need the small cable from kufatec (39880) to connect the rear sensors. You could make your own cable for this one but I was unable to source one of the connectors in a timely manner to do so. I did however modify the 39880 cable like meb did to pass through the side assist data.

The carsystems harnesses is designed to go up the drivers side of the car vice the passenger side like the kufatec harnesses. During installation I decided to use the kufatec harnesses because I thought getting it through the forward firewall was easier on the passenger side compared with the drivers side. Additionally, the wires for the front button and buzzer were longer and easier to work with on the Kufatec harness. I did one thing different from meb’s install. I ran the power to the trunk from the driver side fuse blocks down the drivers side and to the trunk since I already had pulled the trim up for possibly installing the car systems harnesses. I didn’t need to run power to the passenger fuse block and put another fuse there.

With the help of meb for coding using VCDS I was able to get the project done. It took two full days. I ended up spending close to $750 because of the extra harnesses, but I was able to get the project done when I had the time available and didn’t need to order extra parts. You could do the project by only ordering the carsystems 8 sensor full upgrade for about 450 euros plus shipping, and painting if you wanted. You could then make the small rear harnesses or just buy a Kufatec one. The other route is to order all the Kufatec harnesses and order all the other hardware separate like meb did. I ordered my Kufatec harnesses from www.bks-tuning.com in Germany so I didn’t have to wait the month to order the Kufatec harnesses from the US distributor. The price, even with shipping was still reasonable using this route.

Overall a challenging project, but one I am very glad I completed.

So everything is now mounted and sensor are in the front fender, but Kufatec did not supply any wiring diagram to connect cables that came from the trunk to the front PDC sensor harness. None of the cables are color coded...

It's hard to tell form the picture - but are the wires numbered with a marker? Kufatec says they mark the wires. If they are, then just go based on the markers. If not, I'll post a wire run list.

This is from the factory schematic. One of the Kufatec harnesses is different because it is run from the passenger side of the car rather than the driver side of the car. I believe the flip is made in the bumper harness itself, and that the T6v car side is wired the same. Unplug the sensors on make sure that I have the pins right on the T6v side, otherwise your display will show the wrong sensors (although it could be a quick fix back at the T12e connector).

T12e = connector on J446 (Module 10)
T6v = connector in bumper

T12e pin 2 to T6v pin 1 (which connects to pin 1 on each of the sensors, this is power)
T12e pin 8 to T6v pin 5 (which connects to pin 2 on right front parking aid sensor)
T12e pin 7 to T6v pin 4 (which connects to pin 2 on right front center parking aid sensor)
T12e pin 6 to T6v pin 2 (which connects to pin 2 on left front center parking aid sensor)
T12e pin 5 to T6v pin 3 (which connects to pin 2 on left front parking aid sensor)
T12e pin 1 to T6v pin 6 (which connects to pin 3 on each of the sensors, this is ground)

Some of them had numbers, but 2 of them barely had any. One looked like a no.4 and the other like a no.1 But I think I figured it out! :) Appreciated!

Is this the 8 senors kit that would work?

If anyone needs sensors, i'm selling 4

That would be the one that should work. You'd be the first to verify it but I think it should be worth a try. You'd have to route the wire up the lefthand side. Not sure how much wire they supply to access the canbus on the right side of the car.

Thanks.

Anyone knows what size of hole saw I need to cut the bumper for front sensors?

[Andreasmkr]

I used 18mm but I think 17.5 should work as well

[niner]

Thanks for the info.

I think I'll go meb's path: order harnesses from Kufatec, then get other stuff locally. I have parking sensors and console switch already, so getting the whole kit would be wasteful.

[Peeet]

Those will help, I think .

This are the factory drawings, with module 10-park steer assist, from the MY2007 until MY2011.
Its from the OOOO A5/S5, its the same one the OOOO A4/S4

Can someone give me a step by step on how to drill and prep the bumper for front sensors? I have only one time to get it right, so a little guidance would be very useful.

Thanks ahead of time!

Where the holes should be drilled are pre-marked on the back of the bumper. I put blue painters tape across the front around the area the hole would be drilled to prevent any paint chipping. Then I pilot drilled using a small drill bit from the rear of the bumper. There are cross-hairs to show where you should drill. Then I used a metric step bit to drill an 18mm hole from the front. I ordered the metric step bit off of ebay. I cleaned up the edges with an exacto-blade. It was rather simple considering how big of a deal it could be if it didn't work.

Thank you! Do I need to paint the inside of the hole with touchup paint?

You shouldn't have to. The black rubber gaskets that go around the sensors should hide the drilled out area.
