01 View BMW DiagramSee this part on the official exploded view→Regulating lambda probe — a genuine BMW part, number 11 78 1 742 050. The number stamped on the part is 11781742050; BMW's catalog files it under the short number 1742050. You will find it on our Engine shelf, under Exhaust gas control systems. It supersedes the older numbers 1433075 and 1742049, so a part carrying any of them is the same part.
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 16 diagrams, among them Lambda Probe Fixings (11_2181) and Exhaust manifold with catalyst (11_2283). BMW's catalog calls for two of these at each place it is fitted. It weighs about 102 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.
