02 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW lambda Monitor sensor, part number 11 78 1 433 940. The number stamped on the part is 11781433940; BMW's catalog files it under the short number 1433940. You will find it on our Engine shelf, under Exhaust gas control systems.
It fits every E46 body style (320i, 323i, 325i, 328i and 330i, 1999–2006), with the M52 or M54 engines — and the European-market versions.
BMW draws it on 11 diagrams, among them Lambda Probe Fixings (11_2181) and Lambda Probe Fixings (11_2982). BMW's catalog calls for two of these at each place it is fitted. It weighs about 106 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.
