Ok i have an '02 A4 1.8T quattro that has headlight washers. I have tried everything and i am positive that it is not spraying. The windshield one works fine so i know that its not a fuse or anything. It seems like i have to fill up the reservoir alot but the tank is kinda small. Does anyone know where I should start to fix this?

 

They only come on with the headlights on. I sure hope you knew that.....
Buy an owners manual if you don't know the options on your car, audi's are quite complex.

 

And the tank is 4.7 quarts which is the biggest reservoir i've seen on any car. You can only see a part of it, it goes about a foot lower than what you can see.

 

there are two seperate motors for the washer system.... just cause the windshield works doesn't the headlights will to
