I know this is an old post but I'm having the exact same problems and this was the best match I could find in a search.
I've got a 2007 B6 wagon with the Bi-Xenon auto leveling lights and I get flashed by about 50% of the cars on the road and it's ridiculously annoying. I live in the SF bay area and so it's not like I'm the only car out there with Xenons - I think they must be aimed wrong. Last night an oncoming car actually swerved towards us after repeatedly flashing his high beams - a little bit of road rage I guess. I don't need other cars swerving into me with a 10 month old in the back seat.
I took the car in for the 15000 mile service to the dealer who normally does decent work and they told me that the lights couldn't be adjusted, they were auto-leveling, auto-adjusting, and that people just weren't used to the brights. I don't buy this answer - can they be adjusted? If so, what exactly do I need to tell them to do? Get computer readouts?
Skillsflow if you're still around 4 years later, do you remember the outcome of your scenario? Thanks!
