Just lately I have been getting a lot of condensation on the inside of the A3 - to the point were I had ice on the inside when it was really cold a couple of weeks back. I have spoke to the garage and they suggested it could be the air-con until I told them that I didn't have air-con.
There are no obviously leaks (when there is heavy rain there are no damp patches on the inside).
Is this just a common problem with A3s?
Any help appreciated.
