Hi guys. Ive very recently bought A 2002 Audi a4 with angel eyes , I'm not sure if xenon or not . drivers side works perfect but the passenger side is dimmed halfway , so only the bottom half of the two angel eyes on the passenger side is lit. i don't have much experience with cars but my guess is that this is due to a bad ground. Just wondering if any of you guys had the same problem or have any idea on how i would go about fixing this. Thanks.
