I would not be surprised if someone who knows a lawyer would start a class action law suit against BMW to repay all of those who had to pay for the vacuum pump replacement. Anyone know or is a lawyer who can give advice on this matter?

There is a check valve, it is suppose to allow the vacuum to be stored in the booster when there is no vacuum, ie when the car is not running. It allows you one to two stops if the motor quits running. When the check valve does not work the vacuum does not stay in the booster when the car is off. That's why there is a hard pedal.
The Vacuum pump naturally has some oil (engine) in it. If the check valve is bad, some of this oil can get into the booster.
From what I understand some of the check valves do not work well with the oil and because of that it may not be working like a it should anymore.

I am not involved in this problem, and I understand your frustration.
If you had the recall done and the vac pump is not changed who would be responsible for future brake failure or other liability? And would they fix the recalled item again??
It would be like if the ABS system failed and they called back cars for fluid changes, and BTW your ABS is broken.

If indeed they are saying the oil is going into the booster because of the vacuum pump and new check valve will not cure this issue then yes the recall should be including the pump, but replacing the pump will do no good as the pump uses oil to help it seal and replacing it with one of the same design will not change things.

Thanks Allen. I'm gonna come off like a terrible fence-sitter here, but I kinda hope to hear a few guys fought and won a no-charge vac pump to set a precedent. That said, I need to get an alignment also in the next week and it will probably come first so my car will probably not go in for the recall til the week of the 22nd.
