Hello.I have Audi A5 (8T)Can you help me.I need to coding the bordnetz(centralelectric)for ambientenbeleuchtung:Can you tell me which Byte and bit to coding?

or If you can tell me where can I find that information.

In audi service cant help me becouse there is only online codirung.

I have vag-com cable and I know how to do it but I don't know which Byte

Regards Ales

What are you trying to do? Turn the lights on? Turn the lights off? We need more information.

I try to install interior lights.This lights are inside the car left and right under the dashboard on drivers and paseengers legs(fot)and they are also back under left and right seat.This lights are controled with centralelectric(bordnetz) address (09) They are conect on pin T32a/17 and T17i/14
This lights can be regulatet via MMI (brightnes)

This lights can be ordered when you buy the car(in German say Lichtpaket)
They are also in the left and right dors where you pull for open the door.
Sorry for my bad language.
Ales

I find the solution.
I try to code every Byte.And then I find it.
I must change hex code in Byte 16 from 00 to 33
That is for footwell lights front and rear(under the seat)
If I want only front footwell lights then I use Byte 16 from 00 to 11

That's it.Now I must only make a wire and install lights.

Ok.. glad you found a solution. Interior lighting in the US is enabled by default.
