You need to take the snorkel from the MAF sensor to the turbo off when the engine is cold and do two things, first make sure the turbo shaft spins freely without touching the side or catching. Then wiggle the shaft in and out and from side to side, there should be no in out movement and up to 2mm of side to side movement at the end of the shaft.

Make sure you refit the snorkel carefully to avoid crimping the rubber grommet and re-atatch the engine breather pipe
