Steve Posted January 31, 2013 Share Posted January 31, 2013 Hi and welcome to the Audi Owners Club I would run the car for a few days and see if the guage moves. Quote Link to comment Share on other sites More sharing options...
maximinus Posted January 31, 2013 Author Share Posted January 31, 2013 gauge moves fine,but shows about 1/4 of a tank less than what is actually in it.also had plugs changed at the same time.starts and runs perfect. Quote Link to comment Share on other sites More sharing options...
Glen Posted February 4, 2013 Share Posted February 4, 2013 I would guess it's the sensor in the tank that's gone wrong. Sounds as though it's not detecting the right amount of fuel. Worth a further look anyway. Glen. Quote Link to comment Share on other sites More sharing options...
Tech Posted February 17, 2013 Share Posted February 17, 2013 It might be worth removing the fuse for the instrument cluster and leaving it out for half an hour (with the ignition off) then re-fitting it. I can't promise that will work, but its worth a try for nothing. Quote Link to comment Share on other sites More sharing options...
