driver side headlight dipped

[mms77]

Hello,
My 2003 Audi A4 has a dipped head light. I don't think it is the bulb because it is on most the time. It turns on and off every few minutes after i start the car for a while then will just stay on or off. If it is off I can turn my headlights back off and on and it come back on again. All other lights work fine it is just my low beam driver side light that is doing this. Any thoughts on what I can do to fix it? The Audi dealer on the phone was telling me it could be a module which could cost up to 1k to fix.
Thanks for any help!
