fuel gague not working 2.3e audi coupe any ideas

Answer
Stu,
  I'm a PARTS PROFESSIONAL, NOT a Tech but will offer this for your pondering. A fuel gauge is nothing more than an OHM meter. There are 3 things that can affect it's operation, the gauge itself, the wire going from the tank sender to the gauge or the tank sender. When the tank gets low on gas, I would drop the tank and disconnect the wire going to the gauge. With the key "ON", I'd gently "strike" the wire to a clean ground (the frame or body of the car). Have someone watch the gauge on the dash, the needle should move. IF it does, replace the tank sender. IF it doesn't, run a wire from the gauge to a ground and "strike" that wire to see if the needle moves. If it does, replace the wire from the sender to the gauge. IF it doesn't, replace the gauge.
  I'm sorry but this is the best a Parts Professional can do. I can't think of anything else. I hope this helps. Good luck....
