Car heater not working - blowing cold
Hi,
Can anyone help. I had a problem with the temperature gauge not working on an Audi A4 1.8T 2002. I replaced the temperature sensor at the back of the engine but that didn't work so replaced the thermostat. Now the gauge works fine (dial points to 90) but the heater is blowing cold air. There is a leak from the pipe to the coolant flange (coolant flange has been replaced) but i'm toping that up until the pipe arives (o ring failure). When i first did the thermostat the heat was coming through fine but three days later I have just cold air. Is it likely to be an air lock? Thanks for any assistance!
