Alright, all sorted. Well at least the xenon lights are. After going on VCDS, and going into the xenon module, an alignment error came up that somehow Audi service managed to mask. I could not do a new adaptation and basically was stuck so went to the meas values and noticed the rear sensor was giving a very low value on flat surface (15%) while it should be between 50 and 78% I believe. So went under the car and there it was, the so called Audi mechanics, suppose to know what they are doing, who replaced my rear diff, put the sensor bar in the horizontal position rather than vertical. I was fuming and cursing. Great build quality out of Germany but i had nothing but grief everytime something went slightly wrong as they take 3-4 visits to fix it but manage to ruin something else (rear diff was replaced due to them damaging it when replacing the seals, damaged door alum trim when replaced the window regulator, new trim under warranty etc). A socket wrench and a spanner and turned the sucker around and baaam!! al back to normal, no faults, light adjusts to changes in rd heights perfectly and the xenon range is back to what it used to be. Thank god the warranty and free service period is over and now i will take it to third party audi specialist.
The one thing i was disappointed about is that it was not possible to access the steering assistance to change the values. That feature apparently removed in 2007!! whyyyyyy. I hate u for doing that VW group. I know people with GTIs who replaced the steering rack motor with an older one to get the feature back. So now il have to depend on the springs, sway bars and some negative camber to improve steering feel.
