      Just use the part# on realoem for a 325i. I had the same issue on my M42 and ordered from FCPEuro. It looks different than original but works no problem.

          Called the local BMW Dealer, no supersesion information. Looks like a straight hookup, got some vacuum hose, worked no problem without the check valve.

            You should still get a check valve. It is there to hold vacuum in the booster if the engine dies. It is there for safety.

              The same check valve was used in at least the E28, E30 and E36, and a cursory check shows them to be quite available. You really should have one, especially for an emergency situation where you wouldn't want a sudden change in pedal effort.
