Electrical problem
2003 Audi A6 6 cyl All Wheel Drive Manual
----------------------------------------------------------------
My driver side head light is out. Tested the bulb, works fine. Tested the voltage on both sides, it's at about 5 volts. What else can be wrong here?

Hi rdxwkpr,

Check the headlight fuses, one could be blown.

But if I have the same voltage how could a fuse be out? I will check that out.

Thanks

Hi rdxwkpr,

Each side uses separate individual fuses and both circuit are interlinked so when 1 fuse blows, power is now shared by both with one side in reverse flow thus 5 v is present and not 12 v.
