Genuine BMW part 34 33 1 156 703: Check valve support. The number stamped on the part is 34331156703; BMW's catalog files it under the short number 1156703. You will find it on our Brakes shelf, under Other Brakes parts. BMW has since replaced it with 1156579.

It fits the E36 sedan, coupe, convertible and touring (318i, 320i, 323i, 325i and 328i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.

BMW draws it on 15 diagrams, among them Vacuum control - engine (11_4344) and Power brake unit depression (34_0299). It weighs about 14 g (under 0.1 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
