Help TDI Problems

[Gt Tdi Gemz]

Hi Guys and Gals.
New member so hello!!.
I purchased a GTTDI Months ago and it hasint been right from the get go i was driving it home taking my time and it was like it had lost all power the revs died and the needle started to drop but stuck at 60 pm.
Got it back to the garage whare i bought it ,and two new MAF'S later and its still drives like half the power and i dont dare take it over 70 mph.

I put my foot down to the dealer and told him it was going to got to my local vw dealer and it is now booked in to get its codes read on the computer in a few weeks.

In problems are , drives at half the power , idles at over 70 ,sometimes when i put my foot down it billows blue smoke ,

Ive been told that it could be the turbo,but ive also been told it could be the n75 valve??.

I would be really really gratfull if anyone could help my out and give me any other ideas of what it could be , Many Thanks

Hi your post doesnt make that much sense can you clear it up a bit, low power on these is usually one of the following ---bad maf, sticking vnt mechanism, leaky actuator, vacuum leak, kinked nipped/ vacuum pipe, boost leak (blown off or split pipe) or broken turbo. Blue smoke is normally associated with burning oil.
