There does seem to be alot of GTIs out there with the xenon lights setup incorrect.
The factory does not seem to set them up correct and so the dealers do it as you all know not all dealers are the same so alot come out with the lights setup wrong.
I have been blinded many times by Golfs with there xenons set incorrect.
A mate of mine has had his reset by the dealer and seems to have little problems with people now flashing there lights at him. There still very bright so a few still flash but not like they use to. You use to get blinded all the time as people took revenge.
