Hi guys 8 weeks ago I got in my S3 after a long drive (the morning after) and the attached video is what I was greeted with, which was lovely! YouTube - Broadcast Yourself. It's been at a VAG specialist for 6-7 weeks now and following has been changed: Oil pump Cam belt and tensioner 4 hydraulic lifters which seemed to be a bit loose It's still the same! I'm getting really desperate now and want my car back so just wondered if anyone had any ideas as to what it could be? I'm releuctant to take it to Audi for obvious reasons and don't want to drive it to another garage for risk of further damage. The oil spray bar is working and oil seems to be getting through fine so we're really stumped. Any comments appreciated. Many thanks. Chris.
