Low battery and when attempting to start car ran battery further down. Date and time went to default settings and fuel gauge registered empty. Charged battery. Fuel gauge still showing nothing. Picked up answer from Audiworld post. Removed fuse 15 (instrument cluster) & 28 (fuel pump), turned on ignition or to start the car - might not start, but mine did), put fuses back in. Fuel gauge now correct.

There is no reset for the fuel gauge. The sending unit in the fuel tank has probably failed.

There is no reset button for the fuel gauge. Something is either wrong with the gauge or the sending unit in the tank.

There is no resetting a fuel guage. It either works or it doesn't.
The fuel cap has no effect on the fuel gauge and there is no "reset" for this. More than likely the problem is with fuel sending unit in the tank. A less likely cause is incorrect levels of additives in fuel, this can cause the gauge to flucuate erratically.

Fuel gauge not working on Audi 80 1986. I've tested the wires (with a test pencil) that lead to the sender unit and there is no power. I can't find a fuse for this circuit either.
