Has anybody had or heard of problems with water getting into the oil an a 2.0 TFSI Audi S3 engine? I have just been to check my oil and coolant levels etc and there was mayonnaise type cream on the back of the oil cap. Only a bit admittedly but very worrying. Anyone had any similar issues? I wouldn't have thought the head gasket would be an issue on a car with 33k miles on the clock.
