This is a genuine BMW O-ring, part number 11 43 1 740 045. You will find it under Engine (Oil filling, oil dipstick). It supersedes the older number 23 21 1 202 752, so a part carrying that number is the same part.

BMW draws it on 41 drawings, among them two Oil Pan/Oil Level Indicator drawings. It also comes in BMW kits Gasket Set Engine Block Asbesto Free (11 11 0 150 905) and Gasket Set Engine Block Asbesto Free (11 11 1 432 478) and 2 more.
