What's Included

Genuine BMW part 07 12 9 904 831: ISA screw. The number stamped on the part is 07129904831; BMW's catalog files it under the short number 9904831. You will find it on our Supplies & Hardware shelf, under Group 12. It supersedes the older number 9903055, so a part carrying that number is the same part.

It fits every E46 body style (318d, 318td, 320d, 320td, 330d and M3, 1999–2005), with the M47N, M57, M57N or S54 engines.

BMW draws it on 45 diagrams, among them Cylinder head cover (11_2316) and Engine block mounting parts (11_3307). It weighs about 10 g (under 0.1 lb). It also comes in BMW kits Retrofit, coolbox individual seats (2186495) and Retrofit kit, socket (7684232) and 2 more.

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