This is a genuine BMW cap, part number 11 66 7 803 829. The number stamped on the part is 11667803829; BMW's catalog files it under the short number 7803829. You will find it on our Engine shelf, under Other Engine parts. It supersedes the older number 7786179, so a part carrying that number is the same part.

It fits every E46 body style (318d, 318td, 320d, 320td and 330d, 1998–2005), with the M47, M47N, M57 or M57N engines.

BMW draws it on 30 diagrams, among them Vacuum Pump with Tubes (11_2109) and Vacuum Pump with Tubes (11_2335).

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