Anyone have the coding values for the B8.5 LED tail lights?

[chi123]

Doing a rear end conversion on my B8 S4 and need help with coding the facelift LED tail lights. Looking to see if anyone has the coding values for the OEM facelift tail lights, specifically which part of the tail light the channel controls. Did some research but all the links no longer work or they don't tell what the channels are for. Any help in appreciated. Thanks in advance!

Hi mate
I've asked a similar question a couple of days ago in the thread about upgrading to facelift LEDs.

I'm also on prefacelift EURO LEDs and wanting to do the same.

I'm expecting for EURO originals that its just the indictor wire that needs carrying over from outer to inner light as we don't have indicator on the original LED inner but we have everything else (i think).

Using the coding noted in the above thread I've been having a think about the updates. At this stage it could all be wrong but maybe worth a go if you have the lights in and can report back? Obviously note your existing coding in case you are different to mine for some reason.

I've put my original EURO coding then what I think I would try based on that thread. You'll need to compare your US coding and update where needed.

For some reason on the thread link above they all miss out Ch 199 - 202 so I'm thinking US cars don't need to adapt those channels (probably because they have the clear signal lenses on the inner lights already, unlike EURO that are all red).
So for EURO original LEDs like mine I think I need to swap the channels around (see below) so the light signals swap on the pins and light up correctly (but I could be totally wrong).
For US you may not need to make that swap and just leave Ch 199 - 202 as they are (again I could be wrong)

Please anyone else who has done this correct it.

Hey Dudes,

Check out this link to this article.. It helped solved my problem back in April when i upgraded to the Kufatec FL LED Avant Tails

Thanks that is the link I posted above and where I've referenced the coding from. I haven't seen anyone in that thread upgrading from Euro LED to Euro facelift LED (they going from US halogen to euro facelift LED) so the coding is slightly different.

Is your car is a sedan or avant? I should have maybe clarified but mine is a sedan so the tail lights are different.

It's an Avant. Saw yours on your insta, looks nice!
