01 View BMW DiagramSee this part on the official exploded view→Genuine BMW part 11 15 7 840 446: Oil separator. The number stamped on the part is 11157840446; BMW's catalog files it under the short number 7840446. You will find it on our Engine shelf, under Crankcase ventilation. It supersedes the older number 7830948, so a part carrying that number is the same part.
It fits the E46 coupe and convertible (M3, 2001–2006), with the S54 engine.
BMW draws it on 5 diagrams, among them Crankcase-Ventilation/oil separator (11_2996) and Crankcase-Ventilation/oil separator (11_2999). It weighs about 140 g (0.3 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
