My A2 Temp gauge fluctuates between the Centre and Cold. I have changed the thermostat and it seemed to work ok for a couple of months but then the problem returned. It may be as a result of the colder weather returning and seems to be affected by the Climate control being set to warm. (My feet are freezing at any setting below 24 degrees!) Any pointers please?
I don't think there is a problem to be honest, when you turn the A/C on your turning a fridge on so setting it to cold cools the engine even more because the fans are on constant same as a fridge effect now when you use the A/C for heat it works the engine harder and the temp gauge will rise because its creating heat and not cold if you understand that,
