Need some Guidance Recently bought a 2015 A6 premium plus. 4 cyl. Excellent shape. 100000 miles.
A headlight burnt out a few months after on passenger side while my wife and I were on vacation. All other headlights, turn signals and DRLs were still working. I took a off wether cap to replace HID bulb I left cap off for a few days while car seat in garage until I got the new bulb. By accident my wife drove car in the rain. Obviously water got into that headlight assembly. I let it dry out for a few days. I figured DRL would stop working and it did. The problem I have now is all the lights on passenger side except the yellow turn signal will not work. And the DRL on the driver's side also went out. I've replace passenger side bulb, and pass ballast to no avail.
I'm pulling my hair out trying to figure out what the problem is. Is the whole assembly done? Why did drivers side DRL go out also. ?
Lost.
