The number stamped on the part is 51217227120; BMW's catalog files it under the short number 7227120. You will find it on our Interior Body shelf, under Other Body equipment parts. It supersedes the older number 7203917, so a part carrying that number is the same part.
BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.
BMW draws it on 3 diagrams, among them Radio remote control (41_1898) and Radio remote control (41_2028). It weighs about 10 g (under 0.1 lb). It also comes in BMW kits Set of keys with CAS control unit (0037274) and Set of keys with CAS control unit (0037275) and 10 more.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
