This is a genuine BMW protection cap, part number 12 31 1 722 972. The number stamped on the part is 12311722972; BMW's catalog files it under the short number 1722972. You will find it on our Electrical shelf, under Alternator with motor and mounting.

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

BMW draws it on 13 diagrams, among them Alternator Parts 90a (12_0452) and Alternator, individual parts 115A (12_0453). It weighs about 10 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.
