Hi all,

I was on the motor way last week when my coolant warning light came on. Pulled over to check and the tank was almost empty. I only had a service in June, so thought that was odd. Topped it up and thought no more. Haven't used the car for a few days. Yesterday got in the car, started the engine and the light came on again. Checked the level and it was low again.

I've checked under the bonnet and can't see anything that looks untoward! However I've put some cardboard under the car and there is coolant leaking- i can see the pink colour.

Obviously i'm going to book it into the garage. But i'd like to know possible causes before I do.

The engine isn't overheating. The car only had 16,000 mile on it. Its on lease from Audi- but it's out of warranty.!!!!
