I can honestly say I haven't seen anything like this before, so I'm reaching out here for help as my first post. Just bought an audi a6 c5 2.4 quattro automatic 99 modell. It's in great condition, done only 151.000 KM, the headlights nor the turn signals are working, but parkers are working okay, fog lights doesn't work either, interior lights work fine.

Now my question comes, do i replace the starter switch? or do anyone of you think it might be a fire that caused this? The thing is when I use my light horn by turning the highbeam switch towards me. The lights come on, but if i want constant highbeam i can't do that cause it doesn't activate, low beams never works. I was maybe thinking the switch itself might be damaged? Maybe a relay? Thanks for good help in advance.
