Genuine BMW part 51 21 8 177 670: Protection cap. The number stamped on the part is 51218177670; BMW's catalog files it under the short number 8177670. You will find it on our Interior Body shelf, under Other Body equipment parts.

It fits every E46 body style (320i, 323i and 325i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.

BMW draws it on 36 diagrams, among them Front Door-Hinge/Door Brake (41_1101) and Rear door, hinge/door brake (41_1102). BMW's catalog calls for two of these at each place it is fitted.

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