Trunk lid stopper — a genuine BMW part, number 51 24 8 230 139. The number stamped on the part is 51248230139; BMW's catalog files it under the short number 8230139. You will find it on our Interior Body shelf, under Other Body equipment parts.
It fits the E46 sedan, coupe and convertible (320i, 323i, 325i, 328i and 330i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.
BMW draws it on 2 diagrams, among them Trunk Lid/Closing System (41_1368) and Hardtop (54_0330). 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.
