So my 2004 A4 was parked in an outdoor garage for about a week. During this week it rained a bit. When I came back and drove it home, the warning light for the xenon headlight leveling sensor kept going on. (looks like a headlight with an exclamantion point in it) The lights seem to work fine, but this sensor keeps going off randomly.
Where is this sensor? And is it possibly that heavy rains could somehow have shorted something out?
I had to go to the dealer to get some new keys anyway, and mentioned this problem (which started yesterday). He seemed to not be able to find the problem--I thought that maybe the fixed it but halfway through the drive home, the warning came on again.
I have to go back to the dealer in a week or so, so I'll bring it up again. But it's annoying--anyone else have this problem?
