I think my temperature sensor has gone also, I'm getting intermittent read out on the guage. When standing in traffic it seems to work (rising and dropping as the fans cut-in). However, when on a normal journey it does'nt work at all. Is this the sensor? If so where can I locate it on the engine + approx price.
P.S. Has anyone had problems with pinking or such type symptons?
Model: Audi 80 16v 1992 (think might be ACE engine)
it may be the temp senser--but theres a relay/chip/voltage regulator in the dash--its an electrical bit that controls the fuel and coolant guage-when it is faulty it gives inaccurate readings--i have the part number somewhere--in fact i am sure i have read all about it somewhere else on the forum have a search about you may find it
Depending upon the engine type I think there are two or even three temperature sensors for the water. With the KE fuel injection one is used by the ECU to modify the mixture, another is used to start the fans and the third is used as a feed to the instrument panel.
I have located the ECU one on my 1993 80 16V, it is on the back of the block facing the bulkhead, a bit tricky to get to.
The fan one is usually located in the radiator core somewhere and the one feeding the instruments I have not located yet.
