1995 Volkswagen Passat Q&A
1995 Volkswagen Passat Question: How to replace coolant temp fuse.
I would check the Coolant Reservoir Level Sensor, which do go out and when they do, they can set the temp gauge light. VW calls it the Expansion Tank, it goes for about $60, but first try disconnecting the sensor ( it is a 2 wire connector on the bottle) and see if that turns off your light, then you will KNOW. - dandd
