Changed loads of these beefy when i worked at vw best bet is to get a recon one from somewhere like midland turbo they are the exact same units as supplied by vag but half the price and come with a two year warranty iirc. Also if the shaft has snapped the chances are the exhaust is full of oil along with the intercooler.My advise is to remove the intercooler and all boost hoses jet wash them all because if you leave them fit the new turbo and start it up they run on there own oil and the engine will go kaboom.As for the exhaust if its full of oil replace it.
