Well then the only things that come to mind are clogged cat, watsegate issue, clogged oil or water lines that cool the turbo.
The last part is what I would suspect most. If they replaced the turbo, then you'd have a brand new wastegate. If the cat was clogged you would probably have knock and a big loss of power. If the car runs normally and the turbo is not cooling the cooling lines to the turbo are not working correctly and probably clogged somehow. It does not neccesarily have to be in the lines themselves as well, it could be a coolant/oil passage in the engine itself. I don't know how coolant and oil are routed to the turbo in your particular car.
Let the dealer know. Good luck.
