I have an 04 a4 I replaced the H7 pass. light and went to try it out now niether driver or pass. headlights work.
So I went out bought 2 new lights replaced both and still niether work. However the high beams work. I also get a right dipped headlight on the center mess. display.
The right driving light is also out but the left is 0k.

Is there an alternate fuse box because the one on the drivers side didn't have any blown fuses. The owners manual said locatio0n 19, 20 are headlight fuses but there was nothing in those slots.

Any help would be appreciated.
Thanks Floyd

 

It may be the switch itself. You have a B6 chassis car, and I'm not sure about their switches, but on our B5 cars the headlight switch (aka combination switch) is notorious for failure in this way - you can pull back on the stalk to get high beams, but you can't turn the lights on with the switch. Are you able to use high beams by turning the lights on and then toggling to the high beam position, or just get the highs by pulling back on the stalk?

 

I could put the high beams on either way pull back and push the stalk foward.
I measured the voltage out of the switch today the brown wire has power and the purple wire also has power when the switch is in the headlight position.

 

Did you ever figure this out? I am having the same exact problem with a 2001 A4 quattro
