This is an OEM replacement rear (bank 2) turbo assembly for the N54 engine in the 2007-2012 740 and X6 35i. This is a new turbo from Mitsubishi, not a rebuilt unit. Mitsubishi is the original supplier to BMW for the N54 turbos. This is a complete assembly, including the manifold to the engine and the wastegate. 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. This is a new turbo - No core charge.

O-Rings are used to seal various items and without them, you might experience a leak in your vehicle. When doing any sort of work on your air conditioning system, be sure to use new O-Rings to ensure a proper seal. Getting the correct O-Rings can be a chore, but ECS Tuning has made it easy.
