Hi guys and girls,
I drive an A3 Audi 1.8t AGU 1997.
Yesterday whils stationary i noticed my temperature gauge sitting on halfway and slowly really slowly getting higher, i got a little worried so i switched off in case i damage anything, its the first time ive noticed this happen. Driving it sits on halfway and never goes any higher.
Theres more than enough coolant in the tank, and it has recently been serviced.
I was thinking it might be the thermostat but how can i really be sure?
Ive checked the history of the car and 3 years ago its had a temperature sensor and O rings replaced. As well as timing belt and water pump as well as the usual services.
Shall i sit it in stationairy mode again and see if it rises?
Any help would be much appreciated.
