So I recently signed up to Audi-sport, spent hours reading through threads, and plenty of arguments, and went and found myself an S3 8L. Just like to thank everyone for all the great information posted in these threads, it's really helped. So she had a few problems, I serviced her (the full kaboosh, haldex and all, thanks to another good thread) changed the turbo gasket, put a 007 in and now she's running like a dream. Just waiting on some koni shocks, H&R springs, Forge tie bars and poly bushes. But I was sat in her the other day, she was idling, I was twiddling my thumbs and out of curiosity I tapped the throttle, and after leaving some baby gravy in my boxers I noticed that the revs stay put for a few seconds before dropping back to idle speed, like Pavarotti holding a note. Again I've siffted through a lot of threads and am stuck between N75 valve, clutch switch or MAF could anybody please point me in the right direction.
