Hi there, been reading the forum for a while this is my first post. Iv got an S3 (99 APY) Iv noticed theres been a lot of smoke coming from the exhaust the past couple of days so i checked the filler cap today and came across this yellowish stuff on it (iv put a pic up ...hope it works) iv searched the forum and looks like it could be the head gasket? any ideas? Cheers Kev
