Hi,

I am troubleshooting a headlight problem on a '99 A4 Quattro. It appear that one of my headlights if functional on and the other one is not (on the drivers side). I have replaced the bulbs and the fuses for both headlights with no resolve.

I have experienced near zero problems with the A4, but to have a very low mileage. Any further troubleshooting tips would be appreciated. I have been unable to find this problem anywhere on the audi forums.

Thanks!

 

check the ground wires and if power is getting to the unit
