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
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
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
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 the exact, same problem. At least I know I shouldn't take it in to have them 'replace' the bulb. My dealer said that they 'flashed' the chip but that didn't seem to fix the problem. Happens in the cold, and after a few times of switching on and off it seems to stay put. Wondering what the best way to elevate this seemingly 'common' problem to Audi??
Hi,I dont know if your Audi has the same problems as SAAB and VW but they suffer from what is called a dry joint on the circuit board inside the headlamp control relay,what happens is as the board heats up it causes expansion/contraction on the bad solder joint causing all sorts of component failures headlamps just being one of them,remove the relay and open it and on close inspection you will find the (dry joint/s) if your handy with a soldering iron a fraction of the price of some of these relays,you can re-melt the solder on the bad joints to cure the problem.

I had the sane issue with my headlight and they switched the headlight from right to left to see if it was the bulb or the control unit. It turned out it was the bulb and they replaced it.... luckily under waranty. I didn't see a date to your post but mine was done in June 2009 and my dealer was aware of the issue.
AUDI A4- 2005. There is a technical service bulletin for this exact problem. take it to the dealer when this issue has happened while driving. During a daytime drive when cold see if you cant get the light to fail while circling your dealer. As soon as you pull into the service drive do not turn the car off do not flip the switch. I am an Audi Technician for a dealer in Birmingham alabama. Personally this is not my favorite repair to perform; What audi states is that if the bulb flickers the bulb should be replaced; if one side fails the bulb should be swapped left to right if the fault continues with the bulb the bulb is at fault; if the bulb is swapped and the bulb fails again on the same side it is the module. NOW: I currently am working on a 05 A4 that both bulbs both modules have been replaced and Audi has no clue what to advise on a repair. THIS IS AN ISSUE if it has happened to you ask if there is a TSB for this issue or try to find it for yourself.
