Filler cap — a genuine BMW part, number 16 11 1 184 731. The number stamped on the part is 16111184731; BMW's catalog files it under the short number 1184731. You will find it on our Fuel System shelf, under Fuel tank with filler pipe. It supersedes the older number 1184373, so a part carrying that number is the same part.

It fits the E46 sedan, coupe, convertible and touring (320i, 323i, 325i, 328i, 330i and M3, 1999–2006), with the M52, M54 or S54 engines — and the European-market versions.

BMW draws it on 3 diagrams, among them Fuel tank (16_0325) and Fuel Tank/Attaching Parts (16_0372). It weighs about 100 g (0.2 lb).

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