Precat sensor pn?

Craze · 02-22-2021, 07:57 PM

I want to change my precat sens on 2012 m5 f10
Bmw told me pn 11787576673
But esc tuning says 11787614322

Does anyone know what difference is? Thanks

The first part number is correct for precat sensors. OE is Bosch 17187. I looked up the second number and it's a postcat sensor for the 550i.

Thanks so much! I ordered and u are correct

Wonder why ecs and turner page is wrong?
Ive replaced them as preventative maintenance, i have driven my f10 in a month as i just got an f430, man it pulls so hard (tuned and catless ess)

Idk, the ecs catalog seems like a mess for our cars. I got confused too when I was looking for O2 sensors so just went to realoem.

F430's are such beautiful cars enjoy!

I got both pre/post cat sets of sensors from fcpeuro, they have the right stuff.
