But now BMW can't even get it nor do they show a price for it. My question is why did BMW see the need for this. Why was it needed. And why did they stop making it. Just wondering if anyone out there knows anything about this pump and what its intended purpose was since it did not come on the car factory.I have been working on the M for a while now trying to solve my vanos issue, and engine codes. So far no good. We are still working on a couple of things to improve the failure points of the units before i proceed farther. Just stumpled upon this and wondered. Thanks!
