TT 225 2000 Turbo Problem

I'm experiencing severe turbo lag with a massive boost at about 4500rpm. Power delivery was smooth throughout the rev range until I hit about 60K miles. Dealer replaced Turbo Recirculation Valve at the last service but, if anything, this has made the problem worse. Dealer reckons the Air Mass Meter also needs replaced but I don't have faith in their ability to diagnose TT faults and don't want to waste money getting perfectly good parts replaced again. Has anyone else experienced this problem ?

Turbo lag is usually associated with the DV/BPV which is sounds like the dealer already replaced. It's possible that the valve that controls the BPV could be malfunctioning as well.

Another possibility would be a boost leak in the intake somewhere.

We have a 2001 TT turbo that the warranty is about to run out on and it seems to burn a lot of oil (about 1 qt. per thousand) and there is a lot of black soot in tailpipe, but I don't see any smoke coming out. Any ideas about what might be the problem or that the dealer should fix?

This really does sound like an air mass meter fault and it doesnt need to log a fault as it can still be within the parameters but at the very highest point. This has been the case in several occasions.
Good luck
