Electrical diagram

Hi, having a bit of a problem with my headlights, was driving last night and my dipped lights stopped working and only my sidelights were working also my full beams would only work on flash and not on perm.

So far i have checked the fuses in the fusebox in the engine bay and all the fuses look fine and seemed to be working, i then checked the voltage supply to the lights and the dipped lights were only receiving 7.8volts where as they should be at 12v.

If anyone has had this problem before on the same car, i would be more then glad to try the same thing on my car or also a wiring diagram would be really helpful too.

I also think it could be a relay but there is not a relay in the fusebox for the headlights unless it is placed somewhere else on the car.

Oh the car is an 89' Audi Coupe Quattro.

Thanks for your help.
