I have read about this somewhere on the forum a while ago but despite searching I can't find the thread. I took my car, new in January this year, A4 S-Line Avant, to my local dealer this week to get them to turn the rear lights on at the same time as the front LED DRLs. They could not code it to get this to work. What is the code for this, please? I will then go back to dealer with this information. I think just having front LEDs as DRLs was a mistake by Audi. BMWs and Volvos rightly have both front and rear lights on, IMHO. I would appreciate your help. Thanks.
