Lock — a genuine BMW part, number 51 71 8 227 694. The number stamped on the part is 51718227694; BMW's catalog files it under the short number 8227694. You will find it on our Interior Body shelf, under Other Body equipment parts. It supersedes the older number 1960704, so a part carrying that number is the same part.
It fits the E36 sedan (318i, 320i, 325i and 328i, 1992–1998), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.
BMW draws it on the Body-Side Frame (41_0806) diagram. BMW's catalog calls for four of these at each place it is fitted. It weighs about 9 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.
