Unplug the MAF (in the air inlet trunking). If it is no worse with it unplugged, replace it. Other than that? Get the codes read with VAG-COM.
just had a mas air unit as i was told that was the problem but no change but cheers anyway
In that case, get a code reader (preferably VAG_COM) on it, and look here:

Did you check the vacuum hose which goes to the turbo? I had the same problem, the hose was damaged by a mounting bolt of the turbo. If not then maybe the variable nozzel (VNT) inside the turbo is stucked. If it is stucked I suggest you to let it cleaned before replacing it. You'll find alot of information on the internet about it.
