I searched the forum but could not find a similar issue so thought I would open a new thread.

I have a 96 A6 Quattro, 74,000 miles.

High temp warning light comes on after running the car for a while.

Temp gauge seems to be working but does not indicate overheating it maxes out a hair above normal operating temperature.

Fans not turning on but they do work when the AC is turned on.

The OBD II system says temp is normal but occasionally I get spike to high temperature which I believe is the real temp and why the high temp warning light is on.

Trying to diagnose this and was thinking either the coolant temp sensor G62 or the eletronic thermoswitch F76.

Anyone have any thoughts on which one? or both? or something else.
Thanks

1. Wrong forum - your car is a C4.
2. Replace the coolant temp sensor. C4, C5, whatever. They are all garbage.

yeh... realized I was in the wrong spot after the fact.

So what do you mean they are all garbage. The model, the sensors? what?

Pleases enlighten

Coolant temp sensors tend to fail alot on our cars.

Hey thanks!

I have been picking that up also from my searches.

Seems like it is an inexpensive place to start.
