Hi,
After just under 6 months of trouble free motoring that all changed a few days ago. Driving down the M6 after being stuck in stationary traffic, I got a coolant level warning with the coolant level on max, I was doing above average motorway speeds at the time.
I was gonna pull over, but noticed that as I was slowing down, the temp came back down to the middle so i carried on at a cautious 40-50 miles an hour. When I got to my destination, I checked the water and it took about half a jug. Thought thats what it was, so set off again to my new location. Got there no probs, but on the way home, the coolant level flashed again and the temp went to max. I was again doing normal motorway speed at the time. As I slowed right down, temp went back to middle.
Checked water level, and this time it took a full jug, and that was after around 70 miles of driving since I last topped it up.
Since then, the coolant level is on max, but I have only done local driving, taking it very easy, and even when the temp goes up to the middle, the heaters set on Hi are still only blowing lukewarm air, which I assume is part of the problem. I have checked for obvious water leaks from rad etc, but cannot see anything obvious.
The fan also appears to be kicking in.
I am hoping someone here can steer me in the right direction of what the possible culprits are before I take it down to the garage, because the last thing I need right now is a major car repair bill.
Any and help will be very gratefully received.
I should also add that the car is a B6 2.5 tdi audi a4 avant on a 02 plate and its not the AKE engine (Sorry I don't know the code)
