This is a genuine BMW brake master cylinder o-ring, part number 34 31 1 165 092. The number stamped on the part is 34311165092; BMW's catalog files it under the short number 1165092. You will find it on our Brakes shelf, under Foot, brake master cylinder. It supersedes the older number 0309195, 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 30 diagrams, among them Power brake unit depression (34_1137) and Power brake unit depression (34_1138).

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