Upgraded my 2012 Avant from incandescent US-version to facelift European LED tail lights and thought someone may be interested in this writeup. Given the limitations of the Kufatec adapter at the time I embarked in this project, I decided to make my own adapters.

LED Tail Light units (ebay)
8K9 945 096 D
8K9 945 095D
8K9 945 094 E
8K9 945 093 E

Connectors (online Audi dealer)
8K0973705B 2 : Outer
8R0973605 2 : Inner

Cables with pins (online Audi dealer)
000979025E 5 : Outer connector pins
000979164E 4 : Inner connector pins
000979009E 2 : Inner connector pins (ground)

Note: Despite what's reported in other posts, with a little care, you may be able to release and reuse pins from the existing connectors by inserting a needle into the upper part of every pin and unlock the tab that keeps it in place. In my case, I was able to reuse the most of the outer pins, and used brand new pins for the inner connector.

Tools/Other:
*VCDS, to perform the coding to controller 46-Central Conv.

*Two rolls of speaker cable (one pink, one white in this guide) to run two cables from the outer adapter to the inner lights thru the trunk lid (pink), and two from the gray cables out of the controller compartment to the outer lights (white).

*Heat gun, to ensure the wire splitting for the above cable is insulated from the elements

Hardware Installation
Run the extra (pink) cables from both sides of the trunk lid into the D pillar as shown. While I had to remove the plastic covers of the trunk lid, I *did not* have to remove the headliner or D pillar lining; just run the cables using a hard wire or similar thru the D pillar into the lower portion of the trunk walls.

You will also have to run a second pair of cables (white) from the controller panel, with the left one going under the metal trunk lid trim over to the rear left side of the trunk, and the right one just being long enough to reach the outside. Again, with a little care and patience, no need to remove pieces to route the cable.

Build your adapters: Either remove the pins from existing connectors by unlocking their tab, or use the new pins.

To give an idea of the rationale, here's the wiring for an euro-spec car:

Now here's the wiring for my US-spec car (MY2012):

Left Outer
Pin 1: Turn, Green
Pin 2: Brake, Gray-Black (feeds Pin 2 left inner thru trunk lid)
Pin 3: Red Stripe (feeds from Pin 3 left inner coming from controller compartment)
Pin 4: Back-up light, Black
Pin 5: Ground, Brown

http://www.audizine.com/gallery/data/500/medium/IMAG2746.jpg (http://www.audizine.com/gallery/showphoto.php?photo=76667&title=imag2746&cat=500)

Left Inner
Pin 1: Turn, Yellow-Gray
Pin 2: Brake (feeds from Pin 2 in left outer)
Pin 3: Red Stripe, Gray
Pin 4: Fog light, Black-Blue
Pin 5: Ground, Brown

http://www.audizine.com/gallery/data/500/medium/IMAG1659.jpg (http://www.audizine.com/gallery/showphoto.php?photo=76666&title=imag1659&cat=500)

Right Inner
Pin 1: Turn, Gray-Blue
Pin 2: Brake (feeds from Pin 2 in right outer)
Pin 3: Red Stripe, Gray
Pin 4: Fog light, Gray-White
Pin 5: Ground, Brown

http://www.audizine.com/gallery/data/500/medium/IMAG1657.jpg (http://www.audizine.com/gallery/showphoto.php?photo=76664&title=imag1657&cat=500)

Right Outer
Pin 1: Turn, Black-Yellow
Pin 2: Brake, Black-Green (feeds Pin 2 right inner thru trunk lid)
Pin 3: Red Stripe (feeds from Pin 3 right inner coming from controller compartment)
Pin 4: Back-up light, Black-White
Pin 5: Ground, Brown

http://www.audizine.com/gallery/data/500/medium/IMAG2749.jpg (http://www.audizine.com/gallery/showphoto.php?photo=76670&title=imag2749&cat=500)

Use a crimp tool to punch together internal cables. Use a crimp tool plus heat gun, for binding together the additional cables going to the trunk lid and from the controller compartment, as they will be exposed to the elements.

Here's a detail of the wiring done near controller 46-Central Conv. (right side cover in trunk), in order to bridge the gray cable on each side over to the outer lights (see diagram above). Tip: Locate the gray cable on each of the square connectors (black at top, beige on bottom) going into the panel. Then cut where convenient and crimp to bind the extra cable.

http://www.audizine.com/gallery/data/500/medium/IMAG1656.jpg (http://www.audizine.com/gallery/showphoto.php?photo=76665&title=imag1656&cat=500)

I found convenient and ideal to run the outer cables thru the grommet next to the vents. Note how pink and white extra bridge cables go out to the outer light units.

http://www.audizine.com/gallery/data/500/medium/IMAG1661.jpg (http://www.audizine.com/gallery/showphoto.php?photo=76668&title=imag1661&cat=500)

Per Audi's install guide, make sure to vibration-proof loose cables before closing everything.

Coding
Much has been said about the complexity of coding these lights when, in fact, coding is pretty straightforward. Login to the control unit 46 by entering security code 16017. Then, using the Coding opiton, change the following channel values:

Channel Old Value New Value New Purpose
195 14849 14849 Red stripe left
196 14881 14881 Red stripe left
197 13320 5125 Brake right
198 13352 5157 Brake right
203 14849 12 Turn left inner
204 14881 44 Turn right inner
205 13 13 Reverse left
206 45 45 Reverse right
207 73 73 Fog left
208 105 105 Fog right
209 51202 12 Turn left outer
210 51234 44 Turn right outer

Optionally, if you want to enable your LED strips as DRLs, go to 09-Cent. Elect., long coding adapter, and enable the option "Daylight running lights via LED tail lights". Downside: This will also cause your plate lights to also light during the day.

Here's the only picture I've taken of the new lights. The truth is, the car looks much better, even when they aren't on.

Thank you for the quality post. Do you know if the Avant factory wiring changed colors from year to year (on North American models with incandescent/filament bulbs prior to the Allroads which came with LEDs)?

I just remember back when DavidB8 discovered the codes, there was some kind of "rule" that you had to go through him, perhaps that was only if you bought from Europrice? Also once the codes went out in the wild I was under the impression that discussing those was like discussing pirated software or knock-off VAG-COM cables.

I ordered the part numbers from this post. They fit, but the inner connector will have to be depinned to use the plug mentioned here, and the guide pin on the outer housing needs to be shaved down to use the OEM plug.

I went to buy the connectors today. I told the parts guy at audi what I was planning on doing and he said that he advices me not to do it because the harness in the car can't take the load that the new LED tail lights output and the harness ends up burning. has anyone had any problems after switching to LEDs?.

As i used speakercable for outer light aswell , where is not "home environment":) " - twice they have been oxidized(i hope the correct word) and broken, i cant say its "burning out" this is for past 1,5year, so my suggestion for extra cables running to the outer light dont use speaker cable.... All other cables still in good condition...halogen should need more power then led - i belive - not a expert. But members on this forum running those lights while now, have not noticed any complains!

Uhh...the parts guy is just there to sell you parts, not give you advice on installation.

LED's draw less current than incandescent bulbs, so the load is significantly less. Why do you think everyone that puts in LED's into an incandescent housing gets a bulb out warning?

Im running "ebay" leds inside and licence plate lights, no errors yet...regarding taillights- correct coding should clear any bulb error and if i remember correctly bulb-out warning can be disabled as well:)

Thanks for the great write-up! I've ordered the EU facelift tails for my Avant, so now I need to start thinking about how to wire all this up. I have a couple of questions...

First, regarding the pins... I may not install these for a while, but I want to be able to test the lights when they come, so I may not be able to re-use any of the existing pins. So regarding:

Cables with pins (online Audi dealer)
000979025E 5 : Outer connector pins
000979164E 4 : Inner connector pins
000979009E 2 : Inner connector pins (ground)
Are these all really significantly different? They are ridiculously expensive through Audi/ECS for what they are, well over $100 for what is probably $0.50 worth of material. I found some ebay listings that are MUCH more reasonable: 000979025E (http://www.ebay.com/itm/Audi-VW-Skoda-Seat-set-of-6-crimp-terminals-pins-for-repair-wire-000979025E-/181583106264?pt=Electric_Vehicle_Parts&hash=item2a473250d8&vxp=mtr), 000979164E (http://www.ebay.com/itm/Audi-VW-Skoda-Seat-set-of-10-crimp-terminals-pins-for-repair-wire-000979164E-/171380883947?pt=Electric_Vehicle_Parts&hash=item27e718c1eb&vxp=mtr), and 000979009E (http://www.ebay.com/itm/Audi-VW-Skoda-Seat-set-of-10-crimp-terminals-pins-for-repair-wire-000979009E-/171380882331?pt=Electric_Vehicle_Parts&hash=item27e718bb9b&vxp=mtr). Obviously those are just the connectors w/o the wires, but they are selling sets of 6 or 10 for the same as a single one through VW/Audi/ECS. But their images for 000979164E and 000979009E look identical. Just going off of the pictures of what the connectors look like, you would THINK the pins would all be the same. What's the difference between the three different part numbers? EDIT: in the ebay listings, I see the difference between the two that look the same is just the wire size they are designed for. If I'm adding my own wire, that seems moot. The only difference in the 1st one appears that the latch part is turned 90°, but again doesn't seem like that would be critical?

My next question has to do with the wiring. I'm assuming in the following image the yellow jumper wires represent the wiring that is run from the hatch down to the outer lights? Maybe I'm missing something, but why can't that wiring take place at the controller, rather than having to run all that wire?

If i rememer right - Pins for outer and inner are different 64 and 09 are the same - exept 64 is for 0,75mm wire, 09 is for 0,50mm wire!!!
You can buy those from any vw,audi,skoda or seat parts seller as they are repair wires - prices are diffrent quit a bit:)!!!
Yes you can take those -just pins from ebay aswell - more work nothing else, with proper tools easy job!

Regarding wiring, you can modify plan as you wish - result has to be regarding channels the same - nothing else. My one is completly different.

Note:you have different climate, but still isolate connections properly from enviroment:)

Thanks! After looking at the image closer, I realize the reason the wire is run is because that stock wiring has only four wires run to each light, not five. [facepalm] Another thing I'm confused about: if each connector has five wires (x4 connectors), why does the OP list only 11 pins to buy?

You need:

1x Leitung 0,5 mit Pin außen 000 979 025 E

1x Leitung 0,75 mit Pin innen 000 979 164 E

4x Leitung 0,5 mit Pin innen 000 979 009 E

He pinned 2 new wires to outer, so you need regarding this 2x 00979025E

Just snagged a set of facelift LED tails from Ebay. Anyone using the Tuning Fanatics harness (http://www.ebay.de/itm/Ruckleuchten-Adapter-SET-Standard-auf-LED-Ruckleuchten-Audi-A4-S4-B8-8K-AVANT/131179292525?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%2 6asc%3D20140117130753%26meid%3D16e44e303b614387b8b 4b778b6314ecd%26pid%3D100005%26rk%3D2%26rkt%3D6%26 mehot%3Dpp%26sd%3D262250132144)?

I have seen those adapters but have not pulled the trigger on a set of used led tails so post your results if you go with that harness, it will likely give me the push to get a set if you have positive results.

Ok, I actually had these installed a few days ago with the help of a friend who happens to be a VW master tech. We followed hk5ykw's wiring and coding guide. Lights are all working perfectly but we're now getting error codes for the tail lights, blinkers, reverse and fog lights..... it seems like there may have been some missing channel adaptations in the OP's guide. Has anyone else here done this how-to and run into similar problems? Here's a vid of the lights working below. Any help from those who have tackled this on their own would be greatly appreciated.

Your issue have got to be coding related since the wiring appears to be very straight forward. Keep us posted! And good luck!

Problem solved. The OP forgot to mention an important code missing from the code adaptations listed. If you input 0 to channel 181 into control unit 46, it tells the system that the lighting is LED and no longer bulb. Made the change today, no codes. Big thanks to Gunnark100 and rlarsen for the assist. Hopefully someone else will find this helpful!

Nice job[up] - all sorted, small input for future 181=0 (no bulbcheck = no errors in dis and in module 46). Factory setting for 181 regardless which lights(led,bulb,fl led) should be 65535!

Good luck!

Do you have any details on the wiring for the comfort control module? It appears according to the Audi retrofit lighting guide you need to move some pins around within 8K0.907.064.DQ module. I can see the pin numbers but I cannot see the names for the connectors. It mentions T17P and T170.

Just testing an install. I used an aftermarket wiring harness to allow for easier wiring. With the coding mentioned previously I only get the inner strip left/right and fog lights working. Some of my old channel values are different to the ones mentioned. These are channel 197/198/207/208/209/210. Not sure if that makes a difference. This install was facelift LED to pre-facelift Halogen on Audi B8 Avant. Any thoughts on how to get this sorted?

A4 Centaur

12-16-2016, 08:22 AM

^ You got to have the wiring sorted the exact same way with those splices between the two segments (inner and outer) which I assume is why you only get the inner lamps working?

I thought the BCM requires the coding for Ohm/Resistance and or power requirements? Regardless, I picked up my kit from [email protected] and didn't have a problem, except the friggen junction blocks in the hatch area and the ones in the right rear.

The tool I picked up was too big to release the pins (VAS 1978/18).

For coding I would try the following values which is right out of the instructions I received:

Channel 46: enter 16017 (Security Access Code)
Channel 181: Enter 0
Channel 195: 51201
Channel 196: 51233
Channel 197: 5
Channel 198: 37
Channel 200: 9
Channel 201: 41
Channel 203: 12
Channel 204: 44
Channel 205: 13
Channel 206: 45
Channel 207: 5
Channel 208: 37
Channel 209 51201
Channel 210: 51233

I have double checked the values, but don't guarantee anything since I don't know if you have a Kufatec harness or whatever.

12-29-2016, 05:42 AM

All sorted. The wiring on the aftermarket adapter was all messed up, so rather than cut loads of wires I released the terminal connectors to place them in the following setup and coding. This might be of use to some guys as it expands on some of the other guides:

https://www.flickr.com/photos/maverixsnow/31958122945/in/dateposted-friend/

Channel Old Value New Value New Purpose
181 65535 0 Let car know LED lights
195 14849 14849 Red stripe left
196 14881 14881 Red stripe left
197 14852 5125 Brake right
198 14884 5157 Brake right
203 14849 12 Turn left inner
204 14881 44 Turn right inner
205 13 13 Reverse left
206 45 45 Reverse right
207 12 12 Fog left
208 44 44 Fog right
209 0 0 Turn left outer
210 0 0 Turn right outer
200 73 9 Possible Fog left
201 105 41 Possible Fog right

I've shown the old wire colours and how they connect to the new lights, plus the two extra wires per side to connect for the brakes and the red strip. The coding was pretty much as per this guide, just a slight variation on the coding for the fog lights/indicators. This is for a UK spec Audi A4 B8 avant (2008) from Halogen to Facelift LED.

One thing though. I'm getting a bulb out warning for the indicators. Its the internal double speed indicator signal. I've changed to code on channel 181 to 0, so not sure what else to adjust. The indicators are working normally.

Are the taillights OEM or Dectane?

12-29-2016, 09:37 AM

All sorted. I had 6 channels feeding the signals, so adjusted the code to only have 4 and updated the channel values in my previous post to reflect this. All works fine now. Thanks for all your help.

So I'm going to pull the trigger on a set here in the next month or two. Most have built their own harness but I wanted to research what was available from kufatec. Anyone tried this kit? $212 is rather pricey; looks like I can stay under $50 if I build my own.

build your own harness. The Kufatec harness I had tried did not have the correct connectors on either end to work with my US stock tails and Euro LEDs even though I ordered the harness listed specifically for that combination. You won't need the "dongle" if you have or know someone with VAG-COM

when i purchased my car it came with this mod from the former owner.

now i have an issue to troubleshoot.... on my Avant the Right Outer LEDs arent illuminating. this includes DRL/Running light feature as well as Turn Signal; however, the Reverse light IS working.

I swapped the Left and Right housings to confirm that the Housing is not at fault, so it must be in my wiring somewhere.

Where should I look?
I tried poking around with my test meter but could not read any voltage on either the Left or Right sides.... I wonder if this is because its a CAN / LED system?

I specifically found the one extra wire lead that runs from Module-46 to my Right Outer. I checked for Voltage there (on both the right and left sides, actually, using a paper clip to make contact inside the connector) and got nothin'.

Stumped! (help?)

@a4 Centaur i was able to confirm that the housing is OK (i plugged it into the Left side and it worked!) so i think it's somewhere in the wiring that's gone bad, i'm just having a hard time finding voltage with my test meter. what voltage should Module 46 be sending to the LEDs, 5v ?

Just finished up this mod and I'm loving the updated look!

I've made all the code changes as noted in the original post as well as the change to input 0 for channel 181 but I'm still getting a hyper flash in my cluster. The exterior lights aren't hyper flashing at all... just the interior arrows. Any ideas on how to resolve this? I don't have any codes showing up for any lights being out.

One clarification I'd like to make (and maybe it's somewhat intuitive): the square connectors near controller 46-Central Conv. where you're splicing into the grey wires (black at top, beige on bottom)... Beige is passenger side. Black is driver side.

After sitting in the basement for three months, finally completed this mod over the weekend. Big thanks to @Avantagg for sourcing the Euro-spec lights and @A4 Centaur for lending me his vag-com for the coding.

A couple tips - I was able to snake the wire without removing any panels entirely, just reached my hand up the side pillar by accessing through either side compartment, and then snaking the wire down by the hinge. For the hatch panel - just loosened the bottom half and was able to fish wire behind the two clips holding the side of the panel, and then up to the inside taillight.

I did build my own harnesses. $50 for the four connectors needed, $15 for wiring and butt crimps, $10 for the 5th wire for outside tails and $8 for terminal connector pins. I only bought one of the 5th wires as it had terminals on both ends, just cut it and used one for each outer tail. So ~$80 once all said and done. Sorry for the crappy iPhone pics.

I'm going to dig this thread back I'm installing LED tails in my 2012 Audi a4 Avant and I'm doing my best to follow along but my car only has 4 wires going to the rear lights each only have 4 going to it.
I have a few questions, is this known and the lights get rewired exactly as specified?
My Tail lights dont follow the same 12345 pin layout mine are 1234 with no fifth cable where does the 5th cable come from aka added from on the pin out from the 46 module.
Also coding, but I'm more worried about where the extra wire comes from and how to rewire that? is it directly from the 46 module that my missing wire is from?
If you need more info let me know I'm looking to complete this, this weekend.
Thanks,

I checked this side using a 12v battery and working out what each connector linked up to bulb wise.

I’m guessing you figured out the wiring? If I remember correctly (and it’s been almost 2 years now), there’s only one value to change in each entry. I believe your telling the car it’s LED versus Halogen. So for the first entry - 195 14848 - it would be 14849, so on so forth.

Maybe @Gunnark can chime in, he’s pretty savvy with this stuff

So had a look at the wiring out of module 46 and am working on figuring out which one I need to tap into in order to sort the wiring out.
I'm wondering if the wire taps into the brake line so that it can do both brake and turn or if it's a seperate pin that needs to be added into the module anyone know?

No need to add any pins(wires) to the module 46, you just need to make bridges between light functions, to get extra ones working, as you had 4pins now 5, means 4 more channels is needed. Just follow wiring in post1 if you retrofitting EU not US lights.

I'm retrofitting EU lights on a US model thus I only have 4 pins per light and in the main post he has 5 pins per light so I'm just trying to find out where the extra 4 are going to come from?

Missing is going to be turn signals on both sides and the brake on the middle (inner lights) that's my 4 extra channels I need to work out where those come from.
Since the brake and turn are combined I'm guessing I need to split a pair of wires joined outside the module? Had a look but the bundle is quite complex to say the least.
-Kurt

Gunnark100

02-18-2019, 11:37 AM

It is up to you, as you see on diagram, two wires each side from outer to inner, so to say "bridges" between brake and tail, pins 2 and 3.

I get that the inner brake and turn will be in a (y'd / joined / connected / paired) with the outter lights, but since my brake and turn is the same bulb (US spec) where do I break the two of those from being paired as I don't want the new brake and turn signals connected.

Hard for me to not overthink it. I like to know exactly what I'm doing before I do something just how OCD works I suppose.
Also I'll try these and revert to the old coding and throw the old lights on if I have issues.
Seeing the coding I don't have turns on the left and right inner lights only ambers on the outter so would I leave those alone?

Alright So new lights are in and they are awesome.
Issues
No errors when turning the car on with the light switch in off position
Pressing brake "right brake light" / "left brake light" MIL on
switch to auto "left rear light" and "right rear light" MIL on
when turning the left and right signals on they blink for 3 cycles turn off and the MIL on, but they work however they seem to lightly pulse for those 3 cycles then no longer will turn on until igniton is cycled.
When turning on side lights they work, but "right rear light" / "left rear light" MIL on
Turning on fog lights "right fog light" MIL on the light works left fog light does not turn on nor does any code appear.

Non issues:
Reverse lights work as they should

Update:
Changed some coding by one value and if anything made things worse the brake now says, "left / brake / turn / signal" and "right / brake / turn / signal" or something along those lines.
Sadly I dont know enough about the coding so don't want to do more harm than good. Any help will be appreciated greatly.

Abort process ASAP.

Too late for that stayed up till about 3am working out the kinks and taking little things from each thread I could see compiled a list and made changes.
Best one I say that help[ed was 203 to 73 which worked and the left fog is now active. Also detection turned off to get rid of those pesky dash notification which also inherently solved the turn signal issue they now work normally the only thing left is sorting out the turn signal inside on the cluster blinks at double speed which is in another thread in which the issue was never solved at least not from what I read. As of right now all the lights function as they should and no errors on dash because 181 is bulb detection and I turned that off for the time being until I can figure out the correct coding needed.

As far as aborting I'm not a fan someone somewhere will have the issue resolution for this and I wont turn back now with everything running.

Completed the Mod all lights working thanks to Ross Tech forums. All lights are working as they should the only issue I have is that the cluster turn light blinks twice as fast the only fix anyone knows of is with the Audi VCP or ob11 which I won't worry about. Thanks for all the help from everyone and anyone looking to do this know it is totally worth it!

Why do yours light up like that? My LED tails do not light up that way at all. The areas illuminated in your photo are the what light up when you step on the brakes. The pictures I included show how they light up without the brakes being stepped on.

Hi! I just installed this on my 2010 Allroad with the oem led lamps but i have one "problem" after upgrading to the facelift. Everything works fine and i have no error codes after using the kufatec wiring and coding, but i have no reverse lights on the car..
On my oem lights the reverse light is integrated in the bulb socket/holder but in my new lights there are nothing, i have one hole on each outer lamp that are for a w16w bulb, but i do not have any calbes or socket for that.

Have you had any similar issues? I guess there are no problem to wire up trough the lamp connectors but i have to find a socket that will fit the lamp, does anyone have any ideas?

where are you guys finding the best place to find the euro spec tails? also what is the preferred method for coding? my halogen tail avant needs this badly lol.

1) I coded the whole kit myself just lots of reading and time I have the whole lot posted on here I think in this thread on what to do, wiring, coding everything (you just have to live with instument panel hyperflash. outside lights flash normal speed).
2) ECS (https://www.ecstuning.com/b-automotive-lighting-parts/euro-spec-led-taillight-set/1337874u1337884u/) tuning sells the Euro kit for $500 free shipping and it's a steal, they dont come with connectors, but I can 3d print some and send them your way prewired and ready for solder / buttconnectors (there was talk of corrosion well mine have no corrosion at all and a nice tight fit).
3) Get on it the mod is simple once you understand what's going on first plunge is just having the lights and VCDS to do the coding and knowing what adaptation is vs long coding the first is what you'll use. Feel free to message me on my email: [email protected] at any time for help. I just wanna see more Avants with Euro spec tails!

Hi, I've read the forum so far, but now I haven't found the answer, so this is my first post.

At the beginning of January I will change the rear lights in a car from the USA.

Can anyone tell me the color to function for the tail light wiring on a B8 A4 Avant? I think I switched some pins when I rewired mine for led tails. I have 4 wires inner and outer.

Smac770

Can anyone tell me the color to function for the tail light wiring on a B8 A4 Avant? I think I switched some pins when I rewired mine for led tails. I have 4 wires inner and outer.

So you are B8.0 (not B8.5), US (not Euro), avant (not sedan), and originally incandescent (not originally LED)? Because all four specifics are required to have any idea what your wiring or coding is. And your factory config, same as mine, would have only three wires to each of the four lamp assemblies. So you either added a wire of your own, or a whole new set of wires, or left something unconnected.

When you say you switched some pins, you mean on the plugs to the J393? Or on the plugs to the tail lamps?

What do you have?
B8.0 Euro wagon LED - is 4 wire outer, 3 wire inner, so not your lamps
B8.0 US wagon LED - doesn't exist
B8.5 Euro wagon LED - is 4 wire outer, 4 wire inner, so maybe your lamps
B8.5 US wagon LED - is 4 wire outer, 4 wire inner, so maybe your lamps

In the end, the concept is simple. Each of the eligible pins on the J393 for rear lamp purposes has an associated channel. However you get bulb X on the rear of the car to J393 pin Y, you put the necessary coding for bulb X on the channel associated with pin Y.

ch 195 - T17p pin 11
ch 196 - T17o pin 10
ch 197 - T17p pin 6
ch 198 - T17p pin 12
ch 199 - T17p pin 9
ch 200 - T17o pin 8
ch 201 - T17o pin 9
ch 202 - T17p pin 10
ch 203 - T17p pin 5
ch 204 - T17o pin 11
ch 205 - T17p pin 14*
ch 206 - T17o pin 1
ch 207 - T17o pin 12
ch 208 - T17p pin 13
ch 209 - T32c pin 31
ch 210 - T32c pin 30
ch 211 - T32c pin 14
ch 212 - T32d pin 18

Don't mess with 211 or 212 (plate lights and high brake lamp). The * on T17p/14 is because that's the wire in the factory harness to which the auto-dimming rear view mirror is attached. So if you move left reverse to another wire other than that wire on the factory harness, you'll have to address the no longer correctly connected mirror situation.

I have not added any wires. I just got a new connector for the inner lights. I'm not sure if I needed to change the arrangement of the wires or put them back in the same order. I have 4 wires on each plug and 4 wires on each light. I am using the Dectane led lights. I ordered them from a place in Germany so I am assuming they are Euro lights. My car is a North American model. I got most of the coding figured out except for a couple things.
1. Outer parking lights do not come on with the switch.
2. Outer parking lights come on with the brake lights.

08-03-2020, 05:31 AM

I'm just confused at what issue you are having some investigation is needed you said "I think I swapped a wire" well you need to go and make a pin out of what you have currently to work against. I have all the factory wiring and coding saved. I have a B8 '12 Avant and the only issue I had is hyper flash on the turns in the cluster but everything works properly Pre FL Lights from ECS the kit is about 500. From reding through the thread the first time I was able to figure out what does what and make the changes so mine did as described. If you read through and take some notes I'm sure you'll at least have a better understanding of what went wrong.

From what I can gather you have bought the wrong lights, but that's just my assumption because we all try and get the best prices, yet sometimes it gets us in trouble. Shoot a pic of the lense side and the connectors you have on inner and outer so we can visually see what we are dealing with. As to help you the best we can.

I'm not sure how to attach pictures. There doesn't seen to be a button for attachments. The only problem I am having is that my outer parking light only come on with the brake lights and not with the switch. I did not change anything on my outer plug. I did not change the order of the wires. My taillights plugged in directly. My inner plug I transferred the wires to the new plug. I put them back in the same order I removed them. So no changes from stock other then changing the inner plug. Still all 4 wires plugs and lights. I have the Dectane tinted lights #RA14KLBSY

08-06-2020, 11:08 AM

So Litec (you might have bought it at Dectane-shop, but they aren't the maker) aftermarket conversion tail lamps. First thing to note is none of the normal dialog here about converting to [Audi OE] LED tail lamps applies. The RA14KLBSY is a specifically tailored wiring and lamp configuration that has to be sorted out independently.

They are obviously not US compliant as they have no side marker light. They do have an independent amber blinker section, which I far prefer to the stacked functionality (blink+brake) that gets used too often in the US.

https://www.carpartstuning.com/litec-led-taillights-suitable-for-audi-a4-b8-avant-2008-2011-black-smoke-with-dynamic-sequential-turning-light-ra14klbsy/5997234-2/
I take it the outer assembly should be "turn" (the amber dots), "reverse" (center white), and "tail/brake" (the lower large red bar)?
And the inner assembly should be "brake" (the red dots), "fog" (center), and "tail/brake" (the lower large red bar)?

Redporsche

08-06-2020, 02:41 PM

The brake light is separate from the parking lights. The parking lights inner and outer are the led lights bars and the brake lights have their own LEDs. Turns are amber on outers only.

Smac770

08-06-2020, 03:06 PM

I find it very unlikely those few little LEDs in just the inner assemblies are going to cut it as legal brake lighting. Don't get rear ended.

So each assembly has a control wire to each of the three lighting elements, with a ground wire common to all three elements.

J393 adaptation channel -> J393 T17o or T17p pin number -> wire of some color scheme -> one of four light assemblies -> pin number on the plug to the light assembly -> lighting element inside the light assembly

You'll have to say which lighting element is connected to which wire color. From the wire colors, we're back to normal Audi documentation and the rest of the path can be known from the published wiring diagrams. The pin number on the plug (on the wiring harness side, not the third party product side) should be sufficient, but since you're looking right at the wires, just go with the colors. At that point, it can be determined which channel coding is going to which lighting element, and which coding needs to be changed to implement the necessary function for each lighting element.

The wires on the car side have not been changed. I only had to change one plug and I just removed the pins and replaced them in the same order.

There is actually more leds in the inner lights then the outer. The inners have a "J" shape and go along the bottom and then around and up top too.

Smac770

08-06-2020, 06:37 PM

Pics would be unnecessarily complicated to decode. From the product pictures of that unit, it should be pretty easy to tell which lighting element goes to which wire on the tail lamp plug. So just list it out here, what color wire on the car harness is connected to which light element. Twelve elements, twelve wire colors, twelves lines of text to type.

Redporsche

08-07-2020, 09:51 AM

Ok, right side wiring at the plug on the car side.
Inner
#1 grey/white = Brake
#2 brown = ground
#3 grey = tail / parking
#4 grey/blue = fog

Outer
#1 brown = ground
#2 black/yellow = turn
#3 black/white = reverse
#4 black/green = brake

The inner lights are working properly. So it looks like the problem is with the #4 wire. I need the taillight to come on with the switch and not with the brake pedal. Same problem on left side.

Redporsche

08-07-2020, 11:23 AM

Left side is a little different.
Inner left
#1 blue/black = brake
#2 brown = ground
#3 grey = parking / tail
#4 grey/yellow = fog

Outer
#1 grey/black = brake
#2 black = reverse
#3 green = turn
#4 brown = ground

So wire on left outer would be #1 that needs attention.

Smac770

08-07-2020, 01:07 PM

Something doesn't sound right. For example, there is no wire to the inner assemblies with a brake activation, unless Audi changed that in MY10-MY12 from how it's programmed on my MY09. There are three lamps on the inner assembly from Audi for the US B8.0 avant incandescent. Two red bulbs, both of which are just tail lights, and the fog light. Here's the visual of what you have presented thus far, except you didn't supply your current channel values as I asked in your other thread. Though better to put everything here now that we're here.

191230

I have to wonder if you maybe got some of those wire to element matches wrong. As the blue/black wire (inner left) and gray/white wire (inner right) are already programmed for fog, yet you ran them to the brake lights.

Keep in mind that German concept of parking light function is not the same as how Americans use the term. We exchange parking lights and corner lights and position lights and tail lights without variation. Parking light function in Germany is something different (because apparently they don't require corner reflectors there), so park is not tail (position).

To change one of the inner tail+CH/LH channel pairs to just brake function, change the values 14849 left / 14881 right to 5 left / 37 right. See how that goes. (channels are in left/right pairs, the right value is always left value +32).

08-07-2020, 04:50 PM

Alright guys, maybe some of you can lend a hand. I don't have an Avant but a 2012 B8 S4 saloon so things may be very different...

I'm in the process of converting to a B8.5 rear end, if it's even possible. Everything is US-spec. I'm still trying to wrap my head around the wiring. My factory LED lamps have a 4 wire outer and 4 wire inner setup.

The B8.5 tails appear to be 5 wire outer and 4 wire inner. I'm confused on some of the wiring diagram verbiage so I haven't made any wiring modifications yet. I'll start with the inner lights since the trunk lid is currently installed on my car. Here's all I've gathered so far:

Factory B8 S4 wiring

Left Rear Tail Lamp Assembly 2 (Inner)
1 - BRN - Ground
2 - BLK - Backup lamp
3 - GRY/BLK - Brake/tail lamp 2
4 - GRY/YEL - Rear fog lamp
5 - None

Right Rear Tail Lamp Assembly 2 (Inner)
1 - None
2 - GRY/WHT - Rear fog lamp
3 - GRY - Brake/tail lamp 2
4 - BLK/WHT - Backup lamp
5 - BRN - Ground

Factory B8.5 wiring

Left Rear Tail Lamp Assembly 2 (Inner)
1 - BRN - Ground
2 - BLK/BLU - Brake/turn signal lamp 2
3 - BLK/RED - Brake/turn signal/taillamp
4 - GRY/YEL - Rear fog lamp

Right Rear Tail Lamp Assembly 2 (Inner)
1 - BRN - Ground
2 - BLK/GRN - Brake/turn signal lamp 2
3 - BLK/GRY - Brake/turn signal/taillamp
4 - GRY/WHT - Rear fog lamp

It appears the backup lamp circuit for B8 and B8.5 differs in that the B8.5 circuit is on the outer lamps, so it would have to be spliced out. That leaves three wires for the inner lights. What other wire am I supposed to be splicing into the inner FL lamps to get them working?

Redporsche

08-07-2020, 07:14 PM

My usage is different from what you have shown.
195-196 = inner parking/ tail lights
197-198 = outer parking/ tail lights
203-204 = fog lights
205-206 = reverse
207-208 = inner brake
209-210 = turn signal
I'm using the led bars as tail / parking lights. I also have a row of leds above outer led bar.
My current coding is,
195-14849
196-14881
197-5125
198-5157
199-0
200-0
201-0
202-0
203-73
204-105
205-13
206-45
207-133
208-165
209-12
210-44

Smac770

08-07-2020, 08:27 PM

Ok, so you've already manipulated the factory coding extensively.
I saw the row of LED dots between the reverse lamp and the bottom LED bar in another pic; I assume there's another wire on the outer module that you just aren't using?

So the pic is correct, showing the current wiring, current lamps, and the factory coding. Obviously, the factory coding doesn't implement the functions appropriate for how the lamps are now connected. You've modified the coding to correct that, but your coding is not 100% effective.

203/204 and 205/206 look fine. 209/210 look fine; the blinker is working fine?

195/196 looks fine if the selected voltage bits are making the correct brightness.

197/198 has problems though. 197/198 should be a tail code, same as 195/196. Instead you've coded them as brake lights. That's why they come on with the brakes. So make them 14849/14881 also.

207/208, if they work fine, great. But I am curious why you set the MSB of the config byte (ie, +128). I would have expected values like I previously mentioned, 5 and 37. Not that it's not ok to have it set. I'm wondering why you set it and if you know what it implements. If we look at a B8.5 Euro wagon with LED, there is a brake only lamp on the inner and outer assemblies. The outer coding does not have that bit set; the inner coding does. The inner brake lamp is the only one with that bit set. Curious what it implies.

Redporsche

08-07-2020, 08:52 PM

There are no unused wires on any plug. That row of leds above the bar on the outer assembly is the outer brake light. My turn signals work fine. I will try changing the codes for 197/198 and see how it works. I can also try to change 207/208 and see what that does.

How does that inner row of red LED dots on the outer assembly get activated?
What it gets used for is up to programming; brake light would seem logical. But if you don't have an input line for a brake signal, ... Maybe it's like trailers, where you give it a combined brake/turn signal and it uses a converter to separate the two to drive separate turn and brake lights? I'm guessing the things came with nothing in the way of instructions or at least design basis?

Alright guys, maybe some of you can lend a hand. I don't have an Avant but a 2012 B8 S4 saloon so things may be very different...

I'm in the process of converting to a B8.5 rear end, if it's even possible. Everything is US-spec. I'm still trying to wrap my head around the wiring. My factory LED lamps have a 4 wire outer and 4 wire inner setup.

Loukou,

The wires are just wires. You need three on each inner and four on each outer for the B8.5 US 4-door LED modules. You only have three on each outer since that's all a B8.0 US 4-door LED has factory. So you're running a pair of wires then, one to the left outer and one to the right outer. Put the left wire on T17o pin 9 and the right wire on T17p pin 10. This will make them channels 201 and 202.

So if it were not for the left reverse wire being joined to the auto-dimming rearview mirror, you would be done. Just work out the plugs and code the channels. But back to that left reverse issue. You have one of three scenarios:

A, you find where the wire from the mirror splices into the original left reverse wire. You disconnect it from the original left reverse wire and you splice it into whichever wire you will use for the new left reverse wire (ie, one of those to the left outer, maybe that new wire you ran). Then you use the original left reverse wire as just one of the three left inner wires you need. So you use the new wires to the outers as the reverse, and you'll code the reverse on 201 and 202.

B, you do not find where the wire from the mirror splices into the original left reverse wire. So. You disconnect the original wire on T17p/14 from the T17 plug. You splice that wire to the new wire you ran to the outer left. You run a new wire to the inner left and attach it to T17p/14. Same as A, you run the new outer wires to the reverse and code reverse on 201/202.

C, you say screw the mirror and disconnect the wire at the mirror. Who really cares about what the rear view mirror is doing at night when you are reversing anyway. Either your head is looking out the rear window or you're looking at the backup camera image. Then the original reverse wire is just another wire, with a really long stray attachment. Here you can use the new outer wires for whatever.

Ok, changed the codes on 197-198 & 207-208.
197-198 fixed the outer parking lights. They work as they should. On with the switch and not the brakes. But, the outer brake lights do not work now.
207-208 increased the brightness of the lights. Works fine.
So now I need to figure out how to turn on the outer brake lights without changing the outer parking lights.

Smac770

08-08-2020, 11:49 AM

Curious. So you find the brake lights are on the inner assemblies appear brighter with the coding 5 and 37 than with the coding 133 and 165. I wonder if there's a reason for Audi to want the outer brake lights to be brighter than the inner brake lights, if the car them. And why this stray bit for that tweaking. For example, the "is fog light" bit is really "turn this light off if I open the rear lid" bit, but only the fog light gets that bit assigned.

So your third-party design is using the same input wire to drive both the red LED bar and the red LED dots? If there are four working light elements and only three wires, you have to validate which wires activate which elements. Go get one of those 12v garage door opener remote control batteries and connect it to the ground and each control wire one by one and find out what actually activates what (on the outer assembly, we seem to have the inner assembly down).

https://www.amazon.com/Duracell-Alkaline-Remote-Battery-Counts/dp/B0094BE64W
Never realized these things were 12v; just thought they were really short AAAs.

Redporsche

08-08-2020, 01:02 PM

Yes, same wire for the outer led bar and the leds for the outer brake light.

Redporsche

08-08-2020, 01:10 PM

I looked at 207-208 again and there is no difference in brightness with 5-37 or 133-165.

Smac770

08-08-2020, 01:57 PM

Ok, so it's still an unknown what that bit is about when set with inner brake only coding.

On the outer assembly issue, so same wire for both light sets. Well, that's not particularly useful. I wonder why they would have done such a thing. Does it appear like the wires for the two panels are joined on the outside, or on the inside (ie, forget about trying to separate them)? Had it been the turn LED dots and brake LED dots, that would have made more sense, and a common splitter could have been used to send the right signal to both dot sets.

But tail and brake? Tail is going to set a particular voltage to the wire, as set by the bits in the voltage byte. Brake application is going to send full voltage. Unless the unit has a splitter that sends the low voltage to the bar and sends that same voltage limit to the bar while passing the full voltage to the dots, both dots and bar are going to come on with tail and go bright with brake.

On the channels going to the outer bar+red dots, add 2 to the value. That will add braking to the current tail+CH/LH function. See what happens.

Redporsche

08-09-2020, 08:33 AM

When I add +2 to 197-198 the parking lights come on with the brake light, but, the taillights still work with the switch.

Smac770

08-09-2020, 09:37 AM

Right, as it should. That new value is tail+CH/LH+brake. The only "problem" being is the LED bar and the LED dots (red) are both going to be on with the position lights on and going to go bright with the brake applied. The inner assembly will not entirely match, where the bar is on with the position lights and the dots (red) go bright with the brake. But with no means to feed the outer bar and red dots separately, it's what you're stuck with.

08-09-2020, 02:16 PM

Loukou,

The wires are just wires. You need three on each inner and four on each outer for the B8.5 US 4-door LED modules. You only have three on each outer since that's all a B8.0 US 4-door LED has factory. So you're running a pair of wires then, one to the left outer and one to the right outer. Put the left wire on T17o pin 9 and the right wire on T17p pin 10. This will make them channels 201 and 202.

So if it were not for the left reverse wire being joined to the auto-dimming rearview mirror, you would be done. Just work out the plugs and code the channels. But back to that left reverse issue. You have one of three scenarios:

A, you find where the wire from the mirror splices into the original left reverse wire. You disconnect it from the original left reverse wire and you splice it into whichever wire you will use for the new left reverse wire (ie, one of those to the left outer, maybe that new wire you ran). Then you use the original left reverse wire as just one of the three left inner wires you need. So you use the new wires to the outers as the reverse, and you'll code the reverse on 201 and 202.

B, you do not find where the wire from the mirror splices into the original left reverse wire. So. You disconnect the original wire on T17p/14 from the T17 plug. You splice that wire to the new wire you ran to the outer left. You run a new wire to the inner left and attach it to T17p/14. Same as A, you run the new outer wires to the reverse and code reverse on 201/202.

C, you say screw the mirror and disconnect the wire at the mirror. Who really cares about what the rear view mirror is doing at night when you are reversing anyway. Either your head is looking out the rear window or you're looking at the backup camera image. Then the original reverse wire is just another wire, with a really long stray attachment. Here you can use the new outer wires for whatever.

Thanks for your reply and insight. I assume the "wires are just wires" because they can be coded to perform different functions?

I'm currently doing the wiring on the passenger inner lamp. I connected the ground and rear fog wires on my factory harness to their counterparts on the B8.5 connectors since that seemed to be the obvious thing to do. I have the BLK/GRN wire (right brake/turn signal bulb 2) on the B8.5 connector left to attach and the original reverse wire remaining on my original harness. I assume it's just a matter of connecting these remaining wires and coding the channels properly?

Smac770

08-09-2020, 03:24 PM

Well, the wires can't be coded, but the channel in the J393 that is assigned to the pin to which the wire is attached can be configured to operate as desired.

Take the right inner module:

US B8.0 sedan LED:

ch 204 -> T17o/11 -> gray/white -> pin 2 -> L47 fog lamp
ch 196 -> T17o/10 -> gray -> pin 3 -> M59 brake/tail 2 lamp
ch 206-> T17o/1 -> black/white -> pin 4 -> M17 reverse lamp
ground, luggage compartment, right -> brown -> pin 5

The US B8.5 sedan LED module is:

ground -> pin 1
pin 2 -> M85 brake/turn 2 lamp
pin 3 -> M70 brake/turn/tail lamp
pin 4 -> L47 fog lamp

So you'll dismount the existing plug on the harness and move the wires to their proper places on the new plug that matches the new lamp module. brown will go on 1, gray/white will go on 4, both gray and black/white will have to have their channels recoded so it doesn't matter which you put on 2 and 3, so long as you record it so you know which channel needs to be coded with which function.

The one complication is as I've already mentioned, that left reverse wire, which is additionally connected to the auto-dimming rearview mirror.

If you haven't monkeyed with the coding on your channels yet, pull the values for 181 through 214 (you have to enter the security access code to see them) and post them here or drop them in a PM (this being the avant thread).

Smac770

08-11-2020, 02:36 AM

Loukou,

Since there's not a B8.0 LED to B8.5 LED sedan conversion thread that I could find, just going to post this question here since we're already here.

Looking at the B8.5 lamps, I'm not sure I understand where the fog light is. What I can find on youtube seems to imply it's the lower inner set of brake LED dots on the inner assembly. Not the white space below the brake rows.

191833

loukou

08-11-2020, 06:09 AM

Smac770,

Correct. The rear fogs appear on the lower brake LED's on the inner lamps, closest to the middle of the trunklid. See the pink box in the attached photo. I'm not sure what the white portion of the lamp is for to be honest - it doesn't seem like they actually do anything other than make it aesthetically pleasing.

Redporsche

08-12-2020, 12:27 PM

Ok, with the current coding I have the parking lights working correctly with the switch but the outer parking lights also come on with the brake lights. They dont seem to be brighter when the brake is applied. So what I did was change the long coding to turn on the rear light bars as drl. So now they are on at all times. So when the brakes are applied it works as it should. I would like to make the parking lights brighter if possible. I have tinted lenses and they are difficult to see in the daylight.

08-12-2020, 07:58 PM

Which part of the instal? I have been working on my coding for a couple weeks. I put the lights in in 20 minutes , lol.

Smac770

08-12-2020, 11:45 PM

The channel value is 16-bits, an 8-bit voltage byte and an 8-bit config byte (speculation). The variable voltage applies to the tail function, thus why you see 00000000 for the first 8 bits on everything that doesn't have a tail function configured.

The incandescent tail voltage bits on my car are 0011 1010 or 0011 0100. B8.5 sample seems to use 0011 0000 or 0010 1100. The LEDs, such as the side markers, are 1100 1000. The oddity is the B8.0 sedan LED that seems to use just 0001 0100.

Red, no idea what you've defined in the config byte at this point, but your voltage byte is probably still the same as mine. So if you wanted to bump it up, set that upper byte to 1100 1000 and see how it goes. If it's just basic tail+CH/LH (config byte 0000 0001), that would be 51201 left, 51233 right.

Hi guys, been reading this thread top to bottom and looking to work out what is required for Euro Avant B8 "LED" to B8.5 Facelift LEDs.

Clearly some coding to do but on the wiring is it just the signal/indicator wire from outer side that needs carrying over to the inner ones or other wiring too?

Then does anyone have coding - Pre FL "LED" to FL LED?

Thanks

dolphik

12-10-2020, 02:40 AM

So you are B8.0 (not B8.5), US (not Euro), avant (not sedan), and originally incandescent (not originally LED)? Because all four specifics are required to have any idea what your wiring or coding is. And your factory config, same as mine, would have only three wires to each of the four lamp assemblies. So you either added a wire of your own, or a whole new set of wires, or left something unconnected.

When you say you switched some pins, you mean on the plugs to the J393? Or on the plugs to the tail lamps?

What do you have?
B8.0 Euro wagon LED - is 4 wire outer, 3 wire inner, so not your lamps
B8.0 US wagon LED - doesn't exist
B8.5 Euro wagon LED - is 4 wire outer, 4 wire inner, so maybe your lamps
B8.5 US wagon LED - is 4 wire outer, 4 wire inner, so maybe your lamps

In the end, the concept is simple. Each of the eligible pins on the J393 for rear lamp purposes has an associated channel. However you get bulb X on the rear of the car to J393 pin Y, you put the necessary coding for bulb X on the channel associated with pin Y.

ch 195 - T17p pin 11
ch 196 - T17o pin 10
ch 197 - T17p pin 6
ch 198 - T17p pin 12
ch 199 - T17p pin 9
ch 200 - T17o pin 8
ch 201 - T17o pin 9
ch 202 - T17p pin 10
ch 203 - T17p pin 5
ch 204 - T17o pin 11
ch 205 - T17p pin 14*
ch 206 - T17o pin 1
ch 207 - T17o pin 12
ch 208 - T17p pin 13
ch 209 - T32c pin 31
ch 210 - T32c pin 30
ch 211 - T32c pin 14
ch 212 - T32d pin 18

Don't mess with 211 or 212 (plate lights and high brake lamp). The * on T17p/14 is because that's the wire in the factory harness to which the auto-dimming rear view mirror is attached. So if you move left reverse to another wire other than that wire on the factory harness, you'll have to address the no longer correctly connected mirror situation.

Hello,

I'm newbie here.
I own A4 B8 2011 Avant (model 2012, manufactured 11/11) from US.
Planning to replace US bulb tail lamps to Euro pre-facelift LED's.
I already got them from Poland and they have connectors (outer 5 pin and inner 8 (used only 4 pins)

I was searching different forums for information recoding bulbs to LED's and found that coding for almost same cars are not always identical.

@Smac770, just curios, where such mapping between channel and block J393 (and probably others) can be found ? And then correspondingly the coding somehow should be calculated, i don't believe it can be done always in "blind" way.

Also i see that my pre-facelift LED lamps (opened it and just seen wiring for bulbs that still present in it(ie brake/taillamp)) are not match the wiring that i see in ELSA for 2008 year car model.

darren.kellum

12-10-2020, 06:38 AM

Just sent you a PM with my Euro pre-facelift LED channel codes and pin positions which may be of help.

Smac770

12-10-2020, 07:20 AM

Darren, fire me a copy of that too if you don't mind. Will add it to my XLS. The complete 181 through 214 if you can.

Dolphik,
There are four details to the tail lights, B8.0 vs B8.5, US vs non-US, 4-door (sedan) vs 5-door (avant/allroad), and incandescent vs LED. So only if all four specifics are the same should information such as part numbers and wiring and coding match.

As a retrofit situation, the question becomes how exact to the target configuration can you become. If you can make the parts and wiring the same as if it had come from the factory, then you simply need a copy of the coding from such a factory configuration and it should fit right in. It's when you can't quite make the physical exactly as it would have been that then you have to figure out how to hack the coding to make things work well enough.

As to the J393 channel to J393 pin mapping, for the tail lights, that was just a matter of experimenting hands on. The wiring diagram from erwin already laid out which pins went to which bulbs, and there are threads on the Internet with the channel coding break down (mostly), so just a matter of matching up the functions coded to the bulbs connected. For the rest, just a matter of rewiring and recoding until each channel was tested for which pin it would operate.

210156

So looking over the before and after, you'll:
move the wire from T17p/13 to T17o/8
move the wire from T32c/31 to T17o/9
move the wire from T17o/12 to T17p/9
move the wire from T32c/30 to T17p/10
add a new wire from T17o/12 to the outer left lamp
add a new wire from T17p/13 to the outer right lamp
(it's your car, suggest you double check my work)

Then put the right wires on the right pins at the plugs to the lamps and just copy over the coding values from a factory B8.0 Euro wagon with LEDs.

Darren, thanks. To clarify the functional description, the values decode to the following, 195-210:

tail + park + CH/LH + brake
tail + park + CH/LH + brake
brake
brake
turn
turn
fog
fog
reverse
reverse

Which generally matches what the wiring diagram says they should be (LO is left outer, RI is right inner, etc):

LI - M58 left brake/tail 2 - pin 8, gray
RI - M59 right brake/tail 2 - pin 8, gray
LO - M4 left tail - pin 1, black/gray
RO - M2 right tail - pin 5, black/green
LI - M86 left brake 2 - pin 2, black/green
RI - M87 right brake 2 - pin 2, gray/white
LO - M6 left turn - pin 4, black/red
RO - M8 right turn - pin 2, black/yellow
LI - L46 left fog - pin 4, gray/yellow
RI - L47 right fog - pin 4, gray/blue
LO - M16 left reverse - pin 3, black
RO - M17 right reverse - pin 3, black/white
LO - M9 left brake - pin 2, black/blue
RO - M10 right brake - pin 4, gray/white
n/c
n/c

We see the M2/M4 bulb terms do not match the 197/198 coded functions. Based on the wiring diagram, I would have expected values 5122 and 5154. But maybe Audi decided afterwards they needed more brake lighting. I don't have the tail lamps so can't comment which elements are controlled by which pins.

So I finished my install and all works great. It was very easy going from Euro LED to Euro FL LED.

All I had to do was:
a) pop pins out of the outer plugs and swap them around to the new positions,
b) run a wire on each side from outer signal/indicator to inner,
c) bought new inner plugs from Aliexpress as they are different and wired the original pins to new positions (incl. new signal wires from outer)
d) change adaptation 181 to 0 to stop bulb warnings

done

I attach an instructions slide that I've made to help out.

I don't know for sure but I'd say you'd possibly need new wires from the comfort controller to light plugs and alter wiring to the plugs (or by adapters) plus updating your coding to led coding.

Hey guys I need help. I have a NA 2009 Avant and just tried to install facelift EU tails. I used the Kufatec wiring harness only, no coding adapter. I've tried using every coding combination I've found, here and on Ross-Tech with no luck. I have no idea if its a wiring issue or coding. I should not I'm using OBDEleven and even tried their coding with no luck still. I was also dumb enough that I didn't save my original values.

195 - Signal left outer - (12){12}
196 - Signal right outer - (44){44}
197 - Brakes left outer - (5){14888}
198 - Brakes right outer - (37){14856}
199 - Channel -
200 - Signal right inner - (44){44}
201 - Brake left inner - (133){14849}
202 - Brake right inner - (165*){14881*}
203 - Fog left - 73
204 - Fog right - 105
205 - Reverse left - 13
206 - Reverse right - 45
207 - Left inner tail, ch/lh - (51201){14849}
208 - Right inner tail, ch/lh - (51233){14881}
209 - Left outer, park ch/lh - (51202){14856}
210 - Right outer, park ch/lh - (51234){14888}

This is what shows up in my OBD11 adaptations. Things to note, my 199 only says Channel and 202 hasn't accepted any code so far. I wrote out multiple graphs of combinations and none have worked. These two were the closest. I think (I already forgot which it was) the one in parenthesis was the closest. But the Brake Lights were acting as the lights, the taillights were acting as the blinkers, and the blinkers were acting as the brake lights. If that makes sense. I've tried the codes from #1 (and #104) and #57.

How do I find out if this is a wiring issue? Any help would be appreciated!

If you need something different, then the wiring harness did not implement the factory relation of J393 pins to tail lamp pins. At which point, it's anyone's guess what you're wiring relationship is.

Hmm I just tried it again and doesn’t work for me. Both the blinkers and taillights only turn on with the brake applied

Edit: I figured out the included wiring was incorrect

Smac770

The channels are hard coded to a specific pin on the J393. So 16 channels, up to 16 pins on the J393 used for rear tail lamp functions (up to 8 left and 8 right, the license plate lamps are ch 211 and the high brake lamp is 212, so those are not part of the up to 16).

If there's any question about the wiring, ie the mapping of the light elements to the channels, just go through 195 to 210 one by one configuring it as the left turn blinker (make sure no other channels have a left turn signal assignment) and see what element lights up each time. It's very direct and without complication. Then you know what light elements are wired to which channels and then code appropriately.

I figured it out using post #1. The harness had the turn signals and brakes switched. Fixed it. The only problem I have now is the dash is hyper flashing but no bulb out warnings.

B8.0 vs B8.5, US vs EU, sedan vs wagon, incandescent vs LED; if any of the four aspects are different, then the factory wiring and coding is different.

Not sure what to offer, the parts catalog page shows only the 8-pin part number that is the 2x4 layout. There's no 1x8 layout plug listed. It seems odd for the US LED one to use an 8-pin socket when only 5 pins are used, when the US incandescent, EU incandescent, and EU LED versions are all 5 pin sockets. It looks like the 2x4 gets used on the B8.5 US LED sedan inner. And it appears Audi dropped the ball documenting both 8 pin variations.

Is the part number not there on the plug already on the car?

Thanks for the input.

I can confirmed that 3D0972708 is the correct connector for the b8.5 allroad led inner taillights and the outer taillight connector is 8K0973705. Other than the different plugs, wiring and coding was exactly the same as the EU version.

Go figure, the B8.5 5-door LED wiring is the same for US and EU, though as you've seen Audi had to find some way to complicate things with the changed connector on the inner modules.

But the coding is definitely not the same, assuming you're trying to implement the original factory coding of that configuration. EU has a turn element and a brake element. US uses both those elements as brake and turn.

For whatever coding you already have in place, it seems you would not notice any difference with either the US or EU part number (for B8.5 5-door LED modules) attached. Which if that's the case, why does Audi bother with different part numbers for US vs EU for B8.5 5-door LED?

Does anyone know if it is possible to go from EU B8.5 FL Avant incandescent to EU B8.5 FL Avant LED as I’ve bought an adaptor from Kufatec and they are saying it is not suitable and they don’t supply such an item.
Many thanks

Smac770

04-19-2021, 09:00 AM

It's possible to go from anything to anything (so long as you stick to the same body type so the lights physically fit), once you fix the wiring and coding.

You'll have to run a new wire to each of the four lamp modules, and a lot of moving wires around on the J393 plugs. Kufatec probably skipped the scenario since it requires new wiring, not just a plug on wiring adapter.

Wow, thanks for that!
Just had a quick look at the adaptors and they do have five pins per lamp module plug so that’s one thing, I’ll be able to make some use of it.
It’s pretty irrelevant but how come it’s so involved when compared to going pre FL avant incandescent to FL avant LED?
Thanks again!

Smac770

04-19-2021, 01:15 PM

It doesn't seem to be any different. In fact, the J393 pins to lamp module pins is exactly the same for B8.0 vs B8.5 for the RoW wagon incandescent. So the conversion of either to B8.5 RoW wagon LED would be exactly the same process.

RSR8

04-19-2021, 01:57 PM

Thanks for looking that up, I only assumed the B8.0 and B8.5 were different as Kufatec informed they only sell an adaptor for the B8.0 which I thought was strange seeing B8.0 and B8.5 incandescent light modules appear to look the same externally plus both have 4 pins

Smac770

04-19-2021, 03:21 PM

I guess it shouldn't have been surprising. If we look, the Euro avant incandescent tail lamp part numbers are the same for B8.0 and B8.5:
outer - 8K9 945 095 left / 8K9 945 096 right
inner - 8K9 945 093 left / 8K9 945 094 right

Smac770

04-23-2021, 02:55 PM

Dean,

So if we look at the chart above for the wagon with B8.5 Euro tails, we see a list of wiring for the incandescent and a list for the wiring of the LED. There's up to 20 wires involved at the lamp assemblies, 16 wires from the J393 and 4 ground wires. We're going to ignore the ground wires for now, as they are all in place; you might just have to move them to the correct pin on the plug.

The cell color is just a quick reference so I can see which wires are at which lamp module. Much faster than trying to look for all the LO (left outer) or RI (right inner) texts. For the incandescent list we have three red, three orange, three green, and three blue cells. For the LED list we have four red, four orange, four green, and four blue cells. So right off the bat, we know we have to run a new wire from the J393 to each of the four modules.

Once you have four wires in place from the J393 to each lamp module, it's just a matter of putting the right pins in the right hole in the plugs. Take the right outer (RO, blue cells). We already have two wires on the correct J393 pins, black/white and black/green. But we need the other two RO wires to be on T17o/8 and T17o/10. So take the gray/white wire from T17p/13 and put it into T17o/8 and then put your new wire that you ran to the right outer (gray if you're were trying to match factory colors) and put it into T17o/10. Now you have the four wires for the right outer at the correct J393 pins; you just need to put them in the correct order in the plug to the lamp assembly.

Doing that sequence, you can simply put in the factory coding as is and be done.

Should you have a problem trying to get the wires to move between the T17o and T17p plugs, it should be possible by stripped back some of the wrap. But it's also not critical to be on the factory J393 pin. Let's take that gray/white wire for the right outer. It's on T17p/13 factory incandescent. You want to move it to T17o/8 for factory LED. But say it's not going to happen. Leave it on T17p/13. But move it to pin 1 (RO/1) on the plug to the lamp assembly as expected. So when you go to put in the coding, the value for ch 200 (which is always for pin T17o/8), just put that on ch 208 instead (the ch for pin T17p/13). The necessary channel value will now get to the right outer pin 1 light element.

All that matters really with the wiring is that the channel value gets routed to the correct lighting element. The channels are hard coded to which J393 pin they control. The pins on the lamp assemblies are hard coded to which light element they operate. Between there, the wiring, it's whatever you need to do to get the right channel to the right light element.

Thanks for taking the time to explain Smac770, really helpful, it all makes sense!
I’m I correct in thinking we’re wiring and coding the lights to the jj393 as if it was an LED equipped car?
Will my J393 accept the coding and extra 4 pins?
Thanks

Smac770

04-24-2021, 01:04 AM

I've never had any issue with putting whatever appropriate coding on any of the 16 appropriate channels.

While the 16 channels are pretty well understood, there are a number of management channels which contain bitmaps of the 16 lighting channels. These are not so well documented, which is why I recommend getting the right wires on the right J393 pins so you can just use the factory coding that you'd find on a LED equipped car. Just put the wires where they would have been, and put the channel values to what they would have been, just seems a lot more reliable approach than hoping to figure out which bits you do and do not need to flip if you start moving things around.

RSR8

04-24-2021, 02:31 AM

Excellent, in theory, can’t go wrong if you’re using factory wiring and coding.
The four extra cables that need running, two to T17p and two to T32c, don’t suppose you happen to know the part numbers of the terminals required to connect to those plugs do you?

04-24-2021, 12:50 PM

Unfortunately, not offhand. That's one thing Audi really sucks at. They can document the plugs well, but not the wire terminals necessary for each plug. I'm sure it's out there to be found somewhere.

Ok, no problems, I’ve got the part numbers off the plugs on tJ393 so that might (or not) help them at the dealership find the correct terminals or repair wires.

The A and G versions are just different colors of the plug.

This is where I normally would go to eBay or such and look for used plugs with the wires still in. For the 17-pin plug, such as this: https://www.ebay.com/itm/174310442137
You can see in the pic it has 7 of the smaller contacts present. For less than $10 delivered (though that's here; I'm sure there's similar for UK eBay).
Or a little more for more and longer wires: https://www.ebay.com/itm/174623621018

Each repair wire from the dealership probably will cost more than that whole used listing.

https://www.a4-freunde.com/showwiki.php?title=Pins+und+alles+was+dazu+gehoert
They are probably the MCON 1.2 or MCP 1.5.

RSR8

04-27-2021, 02:49 PM

Thanks for the above, I’ll probably just buy used plugs then.
I know it’s obvious which plugs are 17 pin and 32 pin and I’ll work out which is T17o and T17p by what wires currently populate them but T32c T32d may prove more difficult to identify as there aren’t any wires going to those from the incandescent light modules, do you know which is grey and which one black?

Quoting this for visibility--is this Kufatec adapter all we need these days?Adapters like these do work fine. These ones are led to facelift led conversion. I think you have halogen originals? So you would be halogen to facelift LED if you want the stripe look led that the facelift has.
That requires more wiring to the module and some extra wires and coding.

For example this kit

@Smac (or anyone else who can help) I'm trying to help Louis above with his incandescent to pre-FL led upgrade on his A4 b8 avant. He bought a plug adapter that essentially sets up the pins in the right places for the LEDs and carries over a wire from outer to inner to make up for originals not having (i think) the side/brake light on the inner cluster https://www.ebay.co.uk/itm/266325518377?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=t6EFQDozTy6&sssrc=4429486&ssuid=b0oLWCLPSkW&var=&widget_ver=artemis&media=COPY(link). The plug provider says that the lights should just work in the right places after plugging in but that does not seem to be the case. I've helped him code ch. 181 to zero. Side/tail lights, signals, fogs and reverse seem to work ok but the combination of brake plus side/tail light seems to not work as expected.

Looking purely at the incandescent original wiring would you say that repinning and bridging a wire from outer to inner would be enough to get pre-facelift euro LEDs working or would expect adaptation too?
If so any clues as to which adaptation codes per channel?

I thought my codes from my original s4 avant prefacelift LEDs (posted a page or so above) would just work for him but seems not.

So B8.0 EU avant incandescent to B8.0 EU avant LED. From the chart above, we see the incans have 4 wires (3 power wires from the J393 and 1 ground wire) to each of the four lamp units (which each have a 4-pin plug), and the LEDs have 4 (3 power wires from the J393 and 1 ground wire) to the inner lamp units (which have an 8-pin plug for whatever reason) and 5 (4 power wires from the J393 and 1 ground wire) to the outer lamp units (which have a 5-pin plug). So I'm confused by "and carries over a wire from outer to inner to make up for originals not having (i think) the side/brake light on the inner cluster". There's no spare wires on the incan harness. In fact, he needs to add another wire to the J393 for each outer lamp unit.

The eBay pics show 4-pin > 5-pin adapters for the outer units, and 4-pin > 8-pin adapters for the inner units. Ok. You'll need the extra wire on the outer units. But why is there a 5th wire on the inner lamp units?

Looking at the eBay pic, the "upper" outer unit pigtail: (incan = 4-pin end; LED = 5-pin end)

incan/1 > LED/1
incan/2 > LED/3
incan/3 > LED/4
incan/4 > LED/5
brown wire > LED/2

That sort of looks like for the left outer, but not entirely. incan/3 needs to go to LED/2, and LED/4 needs to be the brown wire that needs to be run to 17-pin black pin 9. We see from the chart that 17-pin black pin 9 has a wire on it currently, going to right inner. But we can see it's going to make things much easier wiring wise if we move the wire from 17-black pin 8 to 17-brown pin 9, and the wire from 17-black pin 9 to 17-black pin 8. Now we just need new wires from left outer to 17-black pin 9 and right outer to 17-brown pin 10. Then just reorder the pins on the plug at the outer lamp units and the wiring is done there. You do need the plug adapters for the inners, but there's no rewiring per se; any reordering is just done by putting the wires in the right order on the 8-pin plugs.

It looks like the adapter for left outer is trying to match up functions, but that means the wires are not on the pins necessary for factory programming to work.

The programming certainly can't work as is. As we see in the chart, the lamp functions are not the same for most of the channels.

But this is where "flexibility" comes into play. Take for example the brake/tail assignment. If you're playing it straight legit, you have to move channel values around or new values in channels 195-203. But say you got creative with the wiring so you have the original inner lamp pin 1 (fog) on the new inner lamp pin 4 (fog). So the fog lamp pin 4 is now wired to the old channels that were the fog lights (17-black 8 and 9) rather than where they would be in a factory installation (17-brown/5 and 17-black/11). Then the fog lights are wired to the fog programmed channels, and the fog should be fine. This gets real messy real quick. I'd prefer to get the wiring and programming as it would have been factory, myself.

The most important validation you need to document at this point is ringing out the wiring and confirming which pin on the lamp plugs (the final plugs going into the lamp units, pigtails and whatever included) map to which 17-black and 17-brown pins. Once you have that truth documented, the rest is just connect the dots.

Hello! I have a bit of a tricky question and am looking for a little advice. I recently purchased a complete set of tails from a forum member who I believe bought the set on kufatec (or could have been the second buyer of these tails as I was unable to get their info to ask this question to kufatec directly.) The set came with everything kufatec offers as a package (tails, wiring harness x4 and the coding dongle) and it is brand new. The new tails are going on a 2011 Prestige S-Line Avant with halogen bulbs.

This is the exact kit I bought from the forum member: https://www.kufatec.com/en/audi/a4/a4-b88k/bundle-led-rear-lights-for-audi-a4-s4-avant-facelift-38908

Part numbers for the tails are as follows:
Outer tails:
8K9 945 095 D
8K9 945 096 D

Inner tails:
8K9 945 093 D
8K9 945 094 D

Fun fact: unless you are the original buyer from kufatec, they will refuse to provide any help whatsoever to you. I get it but also way to be dicks.

Anyhoo, I inspected the tails and noticed that the harness plug didn't fit the tail light due to a small notch on the female end of the tail light (see pic). Can I shave this notch down and just start plugging things in? Has anyone worked with this issue before?

Lastly, if anyone has any advice on how to work with these, has the full kufatec install PDF handy etc, I would greatly appreciate it. I'm more than capable of doing the install, I'm just horrible with wiring and don't want to burn my car down. I found a truncated install PDF online but am wondering if the full PDF has more answers. Thank you in advance!
