Hi guys! I've been scouring the web looking for some answers to the problems I'm having with the turbo on my S3. I found a couple of articles, which led me to this forum. So I signed up. The turbo would always cut out intermittently, usually in 3rd gear. The turbo would kick in and the car would surge off, so I'd have to lift off because I knew it would knock the turbo out if I didn't. But recently, it's got worse until now it's just not working at all. I was on the M42 t'other day and it kicked in briefly while going through 6th, but instead of the whistle, I got a screach and then it cut out again. I've had this noise before, which is usually a prelude to the turbo cutting out. I've never had a turbo-driven car before, so I've no idea what's going on. I read about the MAF being a possible culprit, but I'm a total bird when it comes to cars, so I've no idea what that means! What I don't want is to be forking out for a new turbo. So any advice would be great!
