Avant Facelift LED Taillight howto

[Gunnark100]

So i dont quite know how to get that sorted out and what i need that will fit.

After you fit bulb/holder/socket - rev lights must work as kufatec wiring and coding is already in place.

[olehenri]

As far as i have figured out now, i only need the bulb holder as the bulb gets power from the lamp when mounted? As you said over.

Im searching for the part number but have not managed to find anything yet.

[Gunnark100]

the bulb gets power from the lamp when mounted?

Yes.

[olehenri]

If anyone have the part number or any clue where i can find those holders i will be forever grateful 😁

[olehenri]

My local Audi shop could get a pair from Germany so i think its sorted, cost me $60 but i have to have reverse lights 😋

I'd love to have LED tail lights on my Avant.

Thanks, Gunnark. Sorry I was not clear. I just installed the Pre-FL tail lights in my B8 Avant and curious how the OEM brake lights look without head lights on.

Ahah, no problem, i retrofitted prefl also...thanks to Rene, i had brake, so to say full= inner outer and middle bar. As for oem, ive seen only outer one is brighter, or both inner+outer, but without middle bar so to say.

So, i had this in 2012:

[LSANCHEZ1]

doing this mod tomorrow :)

[Mouthlol]

having a real hard time running the wire thru the grommet for the outter lights... any tips?

[planekiller1]

I use a clothes hanger and tie the wire to it, helps me a lot with gromets

So I completed this mod a few years back now but ever since, I have been having a strange hyperflash issue. The exterior lights do not hyperflash... only the interior dash signals. I re-coded all of the values exactly as noted.

It drives me somewhat mad but I'm fairly used to it now. I would be forever grateful if anyone has a fix or suggestions for a fix!

Mine does the same thing havent had time to mess with it and I can live with the dash hyperflashing no other issues tho.

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.

[planekiller1]

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 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!

I appreciate the info, that seems like a pretty good price on tail lights but are those the pre-facelift ones? If i go through with the swap I really want the facelift/lava strip tails, that's the look i'm after.

Yes pre fl and yes I agree but at the same time for the price it was a no brained to me.

[planekiller1]

Ok last ditch effort anyone ever figure out the hyper flash coding to fix it? Been living with it for 6 months not really an issue just seeing if anyone knows the coding to sort it out.
Thanks, - Kurt

[mckulas]

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.

A4 Allroad 2013 facelift with LED.

I have taillights with EU standard (yellow direction indicator), and will be replace.

Does anyone have the correct coding for 46 module?

Thanks a lot!

[Redporsche]

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.

[Redporsche]

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.

[planekiller1]

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.

[Redporsche]

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

[Smac770]

You have to "Go Advanced" and then you can "Manage Attachments".

[Smac770]

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...bsy/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]

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]

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.

[Redporsche]

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.

[Redporsche]

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.

I wish I could figure out how to post pics.

[Smac770]

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]

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]

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]

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.

Audi Litec RA14KLBSY LED tail lamps for B8.0 avant.jpg

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).

[loukou]

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]

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
