Try getting the turbo cleaned out as it could just be sticky veins. Worked on my A3 a couple of weeks ago, doesn't go into limp mode anymore and now pulls like a train. Only cost me £110 so it's worth a try.

Thanks mike boy but only does it over 3000 rpm and the turbo whistling longer then normal.

Mine was doing it a 4000 rpm when accelarating hard. Turbo whistle is pretty standard with these engines. Could possibly be a boost leak if you think the whistle is more noticeable?

Replacing the turbo is your best bet. You don't have to buy brand new one - there are a lot of reputable companies who refurbish turbos.
