Hi All,

I have been having a problem for sometime with my Audi S3.
When accelerating past 29000/30000 revs (just before the turbo kicks in) It sometimes stutters pretty bad then kicks in and goes. I have just had a brand new engine fitted (Piston took the bore out) and the problem is still here with the new engine. It seems to be getting worse. I have replaced the MAF (Genuine part) and it seemed to resolve it for a day then it came back as bad as ever. It does not do it all the time so I very much doubt its a problem with the turbo. I even took it to a garage and they put it on the diagnostics machine. It came back with no fault codes. Running out of ideas and would appreciate some input.

Thanks for your time
