What's Included

This is a genuine BMW O-ring, part number 11 43 1 740 045. The number stamped on the part is 11431740045; BMW's catalog files it under the short number 1740045. You will find it on our Engine shelf, under Oil filling, oil dipstick. It supersedes the older number 1202752, so a part carrying that number is the same part.

It fits every E36 body style (320i, 323i, 328i and M3, 1992–1999), with the M52 or S52 engines — and the European-market versions. It also fits every E46 body style (320i, 323i, 325i and 328i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.

BMW draws it on 41 diagrams, among them Oil Pan/Oil Level Indicator (11_2187) and Oil Pan/Oil Level Indicator (11_3403). It also comes in BMW kits Gasket Set Engine Block Asbesto Free (0150905) and Gasket Set Engine Block Asbesto Free (1432478) 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.
