    If it has an active emissions fault, it will not do a regen even if your have the software unless the fault is fixed.

    " OCCASIONALLY", IF I fill a Def Tank till It accidentally "pools" at the lid. A Def light will stay on for about 6 hours.Did it go out?

    Yes, I have had to do a Full DEF fill up and a few restart cycles and it reset itself… 100%… we’re all good!
