First of all, welcome to the Bimmerwerkz family. I would check the adjusters firstly. Im assuming you have the xenon/projecters headlights, in which the adjusters would be found inside the headlights themselves. These are extremely fragile and can be broken with any wrong succession of movements of the xenon / headlight assembly. I will try to post some pics on how to disconnect and get inside the headlights soon. Only thing is, it will be for my car 99' E39. But i'll show you what to look for in your car also. ( hopefully tonight ) It's night-time in NY. You will need to buy the adjusters if broken , which are plastic, and it would probably run you about $25. I'll help you research that further after you get back to me.
I spend at least 2 hours a day cleaning my car
