The owner before me replaced the front two o2 sensors. I've had the car for a few months now and I'm pulling these codes.
P1250-
P1188- bank 1 sensor 1
P0170- fuel trim bank 1
P0155- 02 sensor heater circuit malfunction
I tried to reset them with a pocket tool but they came right back on. Any ideas?

It sounds like you have a failing fuel pump. If it hasn't been changed in ten years, it's time. HTH

I unhooked the o2 sensor for bank 1 and I was never replaced so I ordered a new one. When I put the new one in will the light shut off on its own. Or do I have to bring it to a bmw specialist shop?

Any ideas if the light will go out on its own?
