I have a 1997 A4 Avant 1.9TDi. In recent months, neither the oil temp or water temp gauges work properly, barely getting above zero on a long run.
Does anyone know if these are linked? I once had a Cavalier (I know . . ) that had several gauges controlled by the same Voltage Regulator behind the dash.
I believe the actual running temperatures are normal, as I don't see any poor performance or clues to high (or low) temperatures. Any ideas?
cheers, Zulu.
