Coupler mechanism right — a genuine BMW part, number 52 10 9 113 982. The number stamped on the part is 52109113982; BMW's catalog files it under the short number 9113982. You will find it on our Interior Body shelf, under Tail trim. It supersedes the older number 7000332, so a part carrying that number is the same part.
It fits the E46 convertible (323i, 325i, 330i and M3, 2000–2006), with the M52, M54 or S54 engines — and the European-market versions.
BMW draws it on 3 diagrams, among them Safety Belt Front Right (72_0386) and Safety belt front (72_0584). It weighs about 70 g (0.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
