ok, cars a '98 1.9tdi(ahu engine) a4. the temperature display on the dash appears to have stopped working, it's been like that for a couple of months the car runs absolutely fine, but the other day i used the car to jump start another one so left it running stationary for awhile, when i got back in it i noticed the dial was at 90 degrees and functioning. any ideas where to start looking for the problem?
