more than likely your jeep was going through a regen when you happened to shut it offI have a 2020 3.0 diesel Rubi. I installed the Tazer mini no problem last night. I have only adjusted the tire pressure so far, but today after a short drive I noticed the cooling fan at a higher rev & a smell of a heated engine that I have not noticed before. I Checked afterwards and made sure I had not changed any other settings and none were changed.
I’m not sure if anyone else has run into this with the diesel or not, so I’m looking for a reason for the elevated cooling fan rev/noise.
