Help locating O2 sensor post cat on Bank 2 on 2012 X5M

eurenn · 10-07-2023, 12:10 PM

All the searching I've done brings up results for the X5 but not the M model. And from what I can tell, it's definitely not the same.

I've already received the replacement sensor, but would anyone know exactly where it's located? I haven't been able to spot it under or over the car, without mindlessly taking things apart to find it yet.

So they're both located very close together. The primaries are right by the turbo, at the neck of the downpipes, before the catalytic converter. The secondaries are right at the cat.

Thanks TTV8M. Does the error/code indicate which one needs replaced? I know it's the post-cat sensors, but not sure which side.
