I've had my 2001 A3 110TDi almost 2 weeks now and am very happy with it but have one or two faults to deal with. Firstly it was empty of fuel when i collected it so i filled her up and reset the trip meter. The gauge didn't go around to full but wasn't to worried about that. However i have done around 200 miles (mostly short town journies) since and the needle was on the red - i was shocked as that's probably worse than my straight 6 BMW i'm getting rid of due to fuel costs!! However i went to fill up and only managed to get about 20 litres in so it's doing ~ 44mpg in town so very good! After filling up, the gauge is still stuck in the red, the temp gauge also basically hardly moves but sometimes if i stop the car when hot and restart it will flick around to 90deg (but not very often). So are the two connected and is there a common fault on these before i start poking around in the wrong place?!
