Having the old problem of temp gauge not working on my 2002 1.8t quattro A4 I replaced the temp sensor located at the back of the engine bay. Its now reading a temp wandering around the 60 degree mark when I'm on the move and only sits at 90 (which I think its supposed to be constantly at once up to temp??) when I'm stationary or in slow moving traffic. Is there another temp feed to the gauge? maybe at the radiator thus explaining the temp fluctuation. I was under the impression that the temp gauge had only 1 input.
Cheers.
