Hi, I own a A2 with heater blower which only will blow cold air.
It is a 2002/03, 1.4 TDi without air con. When I first got it I had to bleed the cooling system and found this solved the problem. However summer came and I stopped using the the blower on hot. Once winter came I found the same problem again, but this time it didn,t need bleeding.
Also duing the summer I took the car on a long trip on slow widing roads, where the car got hot and started to over heat. I was surprised that the cooling fan didn't cut in. Once the switch was brigded out the fan cut in. I fitted a new switch but have never had time to test it.
The engine gets to running temp. as normal but the heater still is cold. I feel that the thermostat is not working properly unless I rev the car at high revs.
Is this a common problem with this model, or even vehicles that don't do must milage per week.
Please help, as I don't really what to change the thermostat if I don't have to. Thanks.
