headlight goes on and off of A6 2.7T 2001 what needs to be done? thanks!
check socket to bulb you do this behind headlight,hood open.
Yes, you may need to have this checked out, I know mom's '04 Audi has HID headlamps, which I am slightly unfamiliar with the operation of, but I know they react differently than regular lamps and have their own sets of problems.
Check the connection to the bulb. Personally, I would replace the bulb also.
