Hi,
What are the accurate part numbers of all the Z4M lambda sensors? (front & rear)

Thanks!

Back:
11781406621
11781406622

Front:
11787540167.(X2)

Am I correct?

The rears are unlikely to need replacement, so just focus on the two pre-cat ones. Instead of paying for BMW markup, do a search for Bosch part number 0258017092. Basically the same thing but much cheaper.

I have had to replace 2 of mines so far. One was pre cat and the other post. Best bet for OP is to decode the fault code via an OBDII scanner and see which sensor needs changing.

Thank you!
But my part numbers as I wrote earlier are correct?

I've used this part for my first and second time replacing the fronts.

Don't remember which one's which. I leave that as an exercise for the student.
