2009 Audi A4 B8 Saloon LED Taillights Retrofit - Hopefully definitive guide soon

[IGL2014]

Finally done the retrofit using this guide (which is pretty good to be fair) and apart from being ripped off by a breaker for the lights, then having to buy some new inner boot lid lamps from Audi (ouch!!!!) and struggling to remove the pins from the old connectors, all went well lol. If anyone is thinking of doing this mod, I would suggest buying the kit from Audi. It is expensive but I ended up paying more in the end by doing it this way. Thanks to the OP for the guide though, it helped my out a lot!

Hiya, ive recently purchased pre facelift led lights, to go on to my 2011 a4 which currently has halogen rear lights. I was just wondering does anyone have the coding? Will be a great help thanks.

Great thread! I'm also looking to change Pre-FL halogen rear lights to Pre-FL LEDs

Does anyone know the coding required for this upgrade? I have found the following but the thread was a little fragmented:

46-Central Conv > Security Access (16017) > Adaptation-10


Channels
181 > 64608
187 > 16368
188 > 16368
195 > 5123 inner brake light with fog
196 > 5155 inner brake light with fog
197 > 5124
198 > 5156
203 > 73
204 > 105


Someone also mentioned changing CH 183 to 0 if 'buld out' errors occur
