Genuine BMW part 54 21 7 004 655: Centering pin. The number stamped on the part is 54217004655; BMW's catalog files it under the short number 7004655. You will find it on our Exterior Body shelf, under Other Sliding Roof / Folding Top parts. BMW has since replaced it with 8204405.
It fits the E36 convertible (318i, 323i, 325i, 328i and M3, 1994–1999), with the M42, M43, M44, M50, M52 or S50 and other engines — and the European-market versions. It also 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 2 diagrams, among them Hardtop Parts (54_0184) and Hardtop Parts (54_0258). BMW's catalog calls for two of these at each place it is fitted.
