    So um yeah, I've had this truck for about a month and today I get our favorite stop engine, limp home debate mode codes blah blah blah....
    it's under warranty thankfully but not my downtime....lol
    Anyhow question is is what type of damage is done to engine if any if you don't stop the motor, like just by idoiling it?

    I’ve idled 24 hrs with a stop engine. You may be able to get a forced regen done and another 3 to 6 hrs out of it to get home. Sometimes more. Depends on your situation.

    Basically your system isn’t regenning and that’s why the red light.

    What exactly does the screen say? Is your def gauge working as it should? Last year when I lost that def sensor in the tank my gauge went to empty and it said scr fault on the screen. It threatened a derate but I drove it 3 more hours to the shop and it ran normal.
