I've read lots about the fuel sender unit playing up in Audi's. Mine seems to work about 50% of the time. Sometimes not moving at all, sometime showing the wrong reading and sometimes showing the correct reading.
The thing that I'm confused about is that my range in the DIS and the fuel warning light always works correctly. Could this mean my gauge is faulty or does the calculation displayed on the DIS not come from the level given by the fuel sender unit?
Its a Tdi 130 if that makes any difference.
