2012 X5M Sport (50i) O2 Sensor issues
I have an issue going on with the O2 sensors in my wifes car. Started out with fault codes indicating a faulty O2 Sensor in bank 2. Ordered a new one and replaced it. I assumed this would fix the issue. Now I'm getting three recurring codes and still the foul smelling exhaust. The new O2 sensor (pre cat) Bank 2 is coated with carbon indicating rich conditions.
1.2C31 Oxygen Sensor before catalytic converter Trim Control.
2.2C2B Oxygen Sensor Before Catalytic Converter System Check.
3.2C2C Oxygen Sensor Before Catalytic Converter 2 System Check.
Relatively new to the X5 so my experience with them is limited. Is there a procedure for resetting values that I'm missing? Thanks I just realized I posted in the wrong section. My bad. FNG
