I have a 2004 Audi A4 1.8T. My right front headlight went out. Replaced the bulb but nothing changed. The old bulb seems to be just fine too. Checked all fuses and they are all good. Please help. High beam which is a different bulb works just fine.

 

Mine is a 2001 Audi A4 1.8 and having the same issue. I think it is the ballast. I called dealer and they quoted me $716.00. So of course that's not happening. I'll be searching in the Junkyards and ebay for the part. Let me know if you find a better solution.
