It's clear that the pump will cost you to have it changed if it's defective. I am curious how many have had the recall completed and NOT need the vacuum pump changed?

I went in for that recall and the dealer tried to get me to replace the pump but I had read a lot of information about it on this and other forums and elected not to replace. No leaks, no problems.

I would like to explain what is going on with all of this as there is some misconception about the failure.
Failure 1 : Cover & Pump housing seals : This is an annoyance only and does not cause the brake booster failure. Both seals available from BMP Designs for $17, that and 1/2 labor and that issue is fixed.
Failure 2 (The Big Failure) : The Pump's larger port has a diaphragm check valve built into the body of the pump. Over time the diaphragm fails. Because the brake booster is always under vacuum after the engine shut off, it pulls oil out of the pump body, passed the failed diaphragm (check valve) and into the brake booster. This causes the failure.
BMW came up with a secondary check valve built into a new hose assembly as a backup as they new the pumps would still fail. Also they wouldn't have to replace the pumps under their dime, just the actual failed components.
This is typical for any car manufacturer. For those that want to sue car manufacturers, good luck. I hope you have a billion in the bank and 500 lawyers. Because that is what they have. Sorry to say...
Hope this helps explain the situation.

E-60 (N62) engine, Vacuum Pump Replacement DIY
Hi There,
Here is a complete DIY video on repairing this vacuum pump leak. That thing costs $400 new and if you have to pay someone to replace it, good luck if you get by with less than paying $800 smackaroos! It looks pretty easy. I followed these instructions two years ago and have had no problem since!

Just an FYI, this is only the superficial repair. Its for the external leaks only and doesn't address the main failure. In short you can replace the seals and the updated vacuum line and that should help, but once the pump check valve fails you take a risk.

you can always put in an external check valve on the line to the booster.
