This is a genuine BMW ISA screw, part number 07 12 9 903 401. The number stamped on the part is 07129903401; BMW's catalog files it under the short number 9903401. You will find it on our Supplies & Hardware shelf, under Group 12. It supersedes the older number 1717938, so a part carrying that number is the same part.

It fits every E36 body style (318i and 318ti, 1992–1999), with the M40, M42, M43 or M44 engines — and the European-market versions. It also fits the E46 sedan, coupe and touring (316i, 316i 1.6, 316i 1.9 and 318i, 1997–2001), with the M43 engine.

BMW draws it on 9 diagrams, among them Lubrication system/Oil pump with drive (11_0440) and Lubrication system/Oil pump with drive (11_0504). BMW's catalog calls for four of these at each place it is fitted.

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
