Hello, I have a 2016 galaxy auto 2.0. done about 110k. Last few days my car has been feeling like it will stall while decelarating. Especiallly coming to a halt. Also when accelerating from low speed the engine sounds like a low rumble flappy noise. Connected my cheap OBD reader to the car and the code above came up along with loads of other inactive archive codes.  Is this definitely a nox sensor issue or something like maf sensor / oxygen sensor?

    Is there any news on this at all on whether this worked? I have exactly the same P2000 code on the ford focus 1.5L non adblue diesel and changed NOx sensor, EGR, cleaned 02 Sensor (which did make the car run a lot better but the code is still there) and now out of ideas.

    Hi Matt,
