This could be faulty diverter valve my car was down on power replaced this and all was ok unlikely to need a new turbo just yet

Sounds like insufficient boost pressure to me. As others have said, replacing the DV is your first port of call!

I wouldn't have thought that there would be a fault code of the turbo has some sort of mechanical failure which meant it required replacement (although it might be smoking a bit).

Tell the technician to stop being lazy and check a few simple things rather than rely on the computer. :rolleyes:

A new DV is ~£40, ed30 it's easy to fit but for a standard gti it's a bit harder to get to but still doable with a good socket set.

I done mine myself  but will need it on ramps unless yours is a later car when they re-located it to a much easier place to get to, I'm sure there is a link to a guide on how to do it on here.  If you want a dealer to do it they will charge you just over a hundred quid this is what I was quoted before I done it myself.

........ a good independent VW garage should sort it for a lot less than a main dealer.
