My 2009 320 CDI CLS gives me P2A00 error code meaning a voltage reading from the oxygen (O2) sensor is outside of normal parameters.
My car only has 1 sensor behind the Cat and no DPF. I have replaced the sensor with a new one but still get the error after resetting it. The car seems to drive fine.
The connection is clean and all wiring looks good.
Is there something else I'm missing that could be tripping the error?
