The number stamped on the part is 11787503123; BMW's catalog files it under the short number 7503123. You will find it on our Engine shelf, under Exhaust gas control systems. BMW has since replaced it with 7570482.
It fits every E46 body style (320i, 323i, 325i, 328i and 330i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.
BMW draws it on 17 diagrams, among them Lambda Probe Fixings (11_2181) and Air Pump F Vacuum Control (11_2203). It weighs about 10 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
