Problem With Brake Booster on a BMW 2003 745 Li

[SpeedWiz]

We have a 745 Li 2003
And we Found oil in the booster so we replaced the b ooster and the pump and tested the feed line. It has vacuum in the booster and it is holding it too. Still no power brakes! Can you please give any ideas if you know what the problem might be

Thank you!

on the vacuum pump is the nipple for the vacuum hose blocked off, or if 03 still uses that vacuum line from the left side, is it attached and not damaged somewhere? also is the one way check valve good?

you already replaced the vacuum pump, right? Def check the check-valve and make certain you bled the crap out of the system.

It is very easy to miss the master cylinder rod inside the booster. That'll make your brakes all messed up. If you've replaced the pump and hose and booster then I'd suspect bleeding or a misaligned rod. I've seen that happen too many times to count at work and from professional techs too! Of course I've never missed one....;)
