I have a problem with my fuel gauge indicator from my 2002 A3 1.8T. Since I bought the car, the fuel gauge was showing that I had more petrol in the tank than i actually had. When the tank is close to empty the fuel gauge indicator is close to the half-mark from the dial. It is definetly a problem with the instrument cluster(I've tested the fuel level sender unit, the BC shows the correct range and the fuel warning light comes on when it is suposed to). It didn't bothered me, but lately I noticed some odd new behaviours from the Instrument cluster. For example, today my BC was showing an average speed of 0 Km/h and an average fuel consumption of 40.6 l/100km(last night it was @ 10.3l/100km). Also, a couple of days ago the fuel gague needle started jumping around after I switched off the lights(the key was not in the ignition). I uploaded a video showing this:
Any ideea for a fix? Or it is easier/cheaper to change the instrument cluster+reprograming the immobilizer? I found more topics related to this problem but none offered a solution to the problem
Have a nice day!
