Anyone know what I should be looking for when data logging with an X3 if P2196 (O2 sensor bank 1 sensor 1 rich) shows up again?
I've read up on the code and some say that when an O2 sensor fails it wouldn't be reading rich so it's not a simple sensor replacement. I do have an aftermarket tune and have reached out to the tuner for support. Just wondering if I can get some thoughts here.
