04 View BMW DiagramSee this part on the official exploded view→Lock button — a genuine BMW part, number 51 21 8 399 243. The number stamped on the part is 51218399243; BMW's catalog files it under the short number 8399243. You will find it on our Interior Body shelf, under Other Body equipment parts. It supersedes the older number 0149217, so a part carrying that number is the same part.
It fits the E36 coupe, convertible and compact (318i, 318ti, 323i, 325i, 328i and M3, 1992–1999), with the M42, M43, M44, M50, M52 or S50 and other engines — and the European-market versions.
BMW draws it on 4 diagrams, among them Door lock front (41_0939) and Front Door Control/Door Lock (41_1062). 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.
