Reinforcement, supporting bearing — a genuine BMW part, number 51 71 7 036 781. The number stamped on the part is 51717036781; BMW's catalog files it under the short number 7036781. You will find it on our Interior Body shelf, under Other Body equipment parts. It supersedes the older number 4287198, so a part carrying that number is the same part.
It fits the E46 sedan, coupe, convertible and touring (320i, 323i, 325i, 328i and 330i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.
BMW draws it on 4 diagrams, among them Guide Support/Spring Pad/Attaching Parts (31_0408) and Front Body Bracket Left (41_1091). It weighs about 340 g (0.7 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
