04 Audi A4 1.8t with Xenon
A few weeks ago I had a problem come out of nowhere. I bought the car about 3 months ago and it has been perfect until now. One night the rear license plate light and rear fog went out at the same time. I got to where I was going and then once I left and started the car back up and they were back on and have been fine ever since. The next day driving to work the left headlight was aiming higher than the right and the left fog light went out at the same time. I am sure you are aware but the audi xenons will auto-level and the left obviously has always been lower than the right, but after that happened it was higher than the left.
Not sure why it happened seems like some weird wiring bug. Fast forward a week later. I bought a vag com cable on ebay and attempted to adjust the headlights with that to make it better that way, but I guess you can't do each headlight individually so I ended up just adjusting the housing to make it better that way, but now the high beam is aiming low on that side, so I know it is just an issue with the left headlight adjust on the xenon portion.
Anyway, I am not sure if you are familiar with the ross tech or any of the vag com stuff to know if there is a way to adjust a single light individually or if I am just going to have to take it to the dealer to get the headlights re-aimed.
