This is the Genuine BMW replacement rear (bank 2) turbo assembly for the N54 engine in the 2007-2010 335. This is a factory BMW rebuilt turbocharger and comes as a complete assembly, including the manifold to the engine and the wastegage. It's highly likely N54 turbos will have to be replaced before 100,000 miles. Signs of a failing turbo are high oil consumption and blue smoke from exhaust (not from a leak or failing CCV system) because the internal oil seals are no longer retaining oil. Without critical lubrication and cooling effects from oil, the turbo shafts and bearings are usually the first to wear and that requires a complete rebuild. You might also see increased turbo lag or failure to hold boost, which is usually a sign of a failing wastegate or some other internal issue. With any internal problems the turbos need to be replaced. BMW rebuilds turbos on an exchange basis so a core charge applies. A refund will be issued upon the return of your original rebuildable turbo.
