I have a 2004 M3, and my headlight on the right side acts funny. Sometimes when I turn the car on it works, other times it does not. Sometimes I wiggle it, and or shut car on and off, which works sometimes. Do you think it is my switch inside of the car with just a loose connection?

Do you have the xenon lights??? If you do I had a similar problem. I took it in and they said it was some sort of actuator for the xenon. not sure exactly. Whatever activates the xenon to light up was going bad. Are you still under Warranty???

No I'm not under warranty anymore, but yeah they are the xenon lights, thanks for the info.
