Have the car scanned. Could be a few things, so a scan and error codes will put you on the right track

Failed DV
Failed n75

Where are you based? Get the car to a dealer or a VW Indie to diagnose

Had a similar problem on my son's car.
Was a fuel pressure issue. Not sure exactly what.
Preshen from CPi(Ex I think) in Edenvale sorted it out.

P0033 turbocharger bypass valve contol circuit

this means the DV is not working. IE there is an electrical stuff up. so no matter that it is the latest type - either the plug is stuffed or a wire or the unit as it sees an electrical issue.

Gents problem is sorted, believe it or not it was a fuse causing all these problems

What Fuse we talking about here?
I have a G5 Gti and many others, it will be good to know if I ever have a problem like this in future.

In the engine bay fuse panel, number F9 its a 10amp fuse its for engine management which controls the turbo wastegate solenoid and more
