Genuine BMW Part

Photos coming soon

This is a genuine BMW expansion tank, part number 34 33 1 157 394. The number stamped on the part is 34331157394; BMW's catalog files it under the short number 1157394. You will find it on our Brakes shelf, under Other Brakes parts. BMW has since replaced it with 1156990.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

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