The only sensible way forward is to get a list of fault codes from the onboard diagnostic system and take it from there. You could either go to a VW dealer, or if you are technically minded you could buy a £15 interface cable, download some free "VAG diagnostic software" and run it on a portable computer.
There are lots of possible reasons for the problem and guessing will not really help. If these suggestions turn out to be sound, please give my reply a "Fixya!"rating, If they do not, please hold off rating and add a comment with more details so I can try to help you further. Cheers, D

Look for a leak on the pressure side of the turbo. I dont think the turbo is bad or else it wouldnt make the wooshing noise. You need to put the engine under a load to build turbo boost. Just giving it throttle in neutral wont work. Block the drive wheels up off the ground SECURLEY and put it in gear up to about 35 mph and ride the brake and give it throttle to find out where the leak is and repair from there

SOURCE: lack of power
Turbo failure is never normally intermittant so I doubt it is a turbo fault.
The wastegate relys on a signal from the ECU via the MAFS.
Mass Air Flow Sensors are very common to fail on VW TDi and this also fits in with your symptoms.
