Regulating lambda probe — a genuine BMW part, number 11 78 1 437 586. The number stamped on the part is 11781437586; BMW's catalog files it under the short number 1437586. 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 6 diagrams, among them Lambda Probe Fixings (11_2211) and Lambda Probe Fixings (11_2479). It weighs about 150 g (0.3 lb).

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