Author Topic: Oxygen Sensor help: Prod date & NGK?? (Read 2895 times)

I went in to my local parts store to get an o2 for my Touring, and naturally I have no VIN for the car that the m42 was in. So, he tells me that production date 08/1990 is the date at which the part #'s differ and that there are (2) different parts/part#'s.....I looked on realoem and found that there are (2) different parts no matter which build date I choose, be it before or after Aug 1990. They only differ on length, 800mm or 940mm.

And I ask him if it's a Bosch and he says 'No, NGK was OE for BMW'.....anyone have any input??

Only thing I can help is check the block for the VIN decal. You might get lucky.

Where would it usually be located?

Most of those sensors were the same. I've used an M20 325i "universal" with no problems. It came with the OEM plug and a longer lead, as you described. You could also use most any four wire pre-cat sensor from what I've heard. Both NTK and Bosch produce similar sensors licensed under a Bosch patent in Bosch boxes with BMW part numbers.

I'd seriously consider a WBO2 like the $200 Innovate unit instead of the pricey OEM BMW part.

OTOH, I found this (Ford Econovan V8 sensors):

Not sure what you'd use to x-ref in Europe, perhaps a mid-90s Mondeo?

The sticker is by the flywheel housing on the engine block on the intake side of engine.

If you do decide to go the LC-1 route, let me know. I have been running one since ~2005 and getting it working properly is actually sort of complicated. It took me years to get every annoying little issue worked out.

the bosch number for the oe fit o2 sen sor is 13 109, if you use a universal make sure you seal the connections VERY well!
