Hi,
Recently my DS4 2015 had the alert in the monitor regarding "fix the engine". I have used the OBD to check what is the error code and it says "P2200 deNox Sensor". Does anyone have any idea what is it? I tried to find videos regarding changing this component but no luck.

Welcome along!
Usually you would get an emissions error with this, and a count down to a non-start situation? The sensor is in the exhaust downstream of the SCR. It should unscrew from the exhaust, but they often seize in and then pull the threads out when you remove it. The part is not cheap, and you need a decent diag tool to reset the de-nox system afterwards.

I do not get any error regarding emission and never get a countdown(just when the adblue is running out). I didnt know that part is not cheap wow, I just did a research here and its expensive, I will probably will take the car to a dealer to take a closer look. Do you know this P2200 might be happening for other issue which the OBD is not aware?
Thank you.
