This is a genuine BMW protection cap, part number 34 31 1 238 040. The number stamped on the part is 34311238040; BMW's catalog files it under the short number 1238040. You will find it on our Brakes shelf, under Foot, brake master cylinder.

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

BMW draws it on the Rear Wheel Brake, Brake Master Cylinder (34_0615) diagram. It weighs about 8 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.
