Try a Revive treatment.
I've found it to be 90% successfull on sticky vane tdi's..

It does actually work
Do you drive it hard? Only time I've had sticky vanes was when my wife had the car for 14 months after we had our last child and she needed the bigger car. Tootling around doing 3k miles in 14 months without a good thrashing coked it up.
Used forte diesel turbo cleaner in half a tank of fuel and an hours thrashing blew it all out, fine again, re treated it a few weeks later and all clear. Since I have had the car back and give it at least one really good high revving hot thrashing once per week have kept it clear since. Having said that I have just recently cleaned up my egr valve and inlet manifold ( heavily clogged) and bit the bullet with the mr muscle treatment in the turbo.
All worth a try before changing the turbo. Ran sweet after the egr and inlet manifold clean.
Just had it remapped yesterday and it was running 159bhp stock on the before run!! Bet it was at 120 before the egr and inlet clean and the turbo me muscle.
All the best.

My TDI 110 started dropping into limp home mode at 3K revs a few years ago, I was mainly doing short runs in it at the time.
After doing a few months research of the possible cleaning options I managed to fix the problem at very little cost. Just some extra diesel and almost a speeding ticket.
I put the engine under heavy load above 3K revs a number of times and that seemed to do the trick. First I just tried running at high revs, in third on the motorway at 4K revs for 5 miles. This didn’t do much other than give me a headache.
I then tried increasing the load on the engine above 3k revs. This involved driving a few miles up a local dual carriageway warming the car up and checking for speed cameras then coming back the other way flat out, holding the loud peddle down for as long as you dare. Did this a few times over a few weeks and that stopped the over boost.
My job has changed and I do a motorway commute most days with a couple of steep hills. Once every week or two I floor it up the one of the hills and make sure the engine is pulling over 3K revs. Haven’t had the over boost come back, plus it can be fun.
I guess it depends how far gone your turbo is, but I would recommend trying to ‘self clean’ it first.
If that doesn’t work a £5 can of over cleaner maybe worth a go, there are few videos on Youtube showing this.
Personally I would try the water in the air inlet trick first, again videos on youtube about this. Partly because I’m getting too old to be crawling under cars and I also don’t fancy a snapped exhaust stud on a car that’s over ten years old.
If all those failed only then would I consider paying to have the turbo reconditioned.
