Audi A4 "left dipped headlight" problem




By dpodca on Dec 16, 2008

" "
The left headlight of my 2006 Audi A4 quattro has this annoying -- and
dangerous -- problem:
1. The left headlight flickers
2. It then turns itself off
3. The message "left dipped headlight" appears
4. The message is changed to a sign indicating that the lightbulb has
failed.

If I turn the light off (Note: We're talking about driving at night
here) and turn it back on again, the light will become normal again,
for about a few minutes and then the cycle repeats itself.

This problem is intermittent. It has been occurring a lot recently
with the cold weather. I can't tell for sure whether it is
temperature related.

My Audi dealer said that Audi knows about this problem but doesn't
know how to fix it -- changing the light bulb doesn't solve the
problem.

Has anyone encounter this problem and get Audi to fix it?

02 A4, and the temp recently dropped heavily here. I noticed that my left headlight is out and I'm getting the dipped message as well. I'll check this afternoon as I have heated parking. Will be interesting to see if it works when warm.

-   I have a question for all of you, Mine started doing the same thing tonight, I did notice that all of you are having the problem when it is cold out, it was raining here last night when my light went out. My question is do all of you have a H.I.D. lighting system?? -   mattmann88

-   I have the EXACT same problem. This is a perfect description of the issue.
I took my car to the dealer twice for this with no resolution. At first they said it was a bad or missing washer block that they had to special order. They replace that but it made no difference.

The problem seems to occur every time I leave the office parking lot in the evening > cold engine, acceleration, left turn, slight bump/vibrations in the road. Left headlight goes off, I turn the lights off then back on and it "fixes" the problem. For me, it does not seem to reappear until the next day. But it does happen (almost) every day. If I go particularly slow on the parking exit, I see the light flicker but it does not shut off.

It's certainly electrical/mechanical, it's reproducible, but so far, not fixable. It seems that cold weather amplifies the problem. When the car is warm, it never happens!

I look forward to a resolution.

I have the same issue on my 2002 A4. According to my Audi dealer mechanic, there is a sensor on the front suspension that controls the angle of the headlight. Replacing this may resolve the issue.
