Headlight Range Control Defective - 2004 A4 with Xenons
Is this likely a level sensor or headlight motor problem? Is there some way I can diagnose it with the VAG-COM so that we don't buy the wrong parts to fix it? Is it possible to correct this by simply running the realignment process or is that a waste of time?
I'm going to dig into it this weekend, so any tips will be most appreciated.
