I'm a relatively new owner of a 2004 Audi A6. I've noticed inconsistencies with my Xeon headlights. Sometimes they work perfectly aimed high enough etc. Other times, the lights seem to be pointed down too low and I can't see that far in front of me. The next time I get in the car they're fine.... I've also noticed that when I turn the lights onthey do a quick raise lower thing,the lights are typically aimed accurately. I would say only half the time that I use the headlights that the car does the quick raise/lower aiming thing. Is this a typical issue or is my car not doing what it should? I should also note that this applies only to the low beams. The high beams always work perfectly.
