Audi A4 "right dipped headlight" problem, was Audi A4 "left dippedheadlight" problem

I took my A4 to the dealer and two things were done:
- the code (presumably software version) for the light were checked
and it was correct
- the igniter was changed
And the result?
- the problem with the left headlight disappeared
- the same problem begins to occur on the right headlight !

Has anybody seen this weird problem? Can the left headlight circuitry
somehow interact with the right one?

Or did the shop simply swap the igniters?

sounds more like it...........while backcharging Audi for a new one.

Yes, I have the same problem on the left headlight and have found if I
cycle the headlight switch the headlight will light up again and most
times will remain on.

However it is extremely annoying and it is dangerous. I was going to
take it in to the Dealer to have it addressed but wasn't sure just
exactly what they would charge me for something like this. I understand
if you need to replace the whole headlight assembly it is incredibly
expensive.

I sure hope that I don't run into the same problem that you are
experiencing. I believe that there may be some electrical gremlins in
these vehicles that should not be there. I also have the airbag light go
off and on when I am driving. This is quite disconcerting for my wife. I
have had both Porsches and BMW's before and have never experienced these
kinds of problems.

Overall I love the car but these gremlins are getting the better of
me.:evil:
