Another IMS bearing thread

He charges $1400 to do this on cars with Tiptronic, which includes all parts

The part he is center punching is the only thing holding the oil pump drive key from falling into the IMS shaft during operation. I see these failures occur without the assistance of a center punch.

It helps to understand the anatomy of the patient before performing the surgical procedure.
