Here's one I haven't seen on here.... I am using the edge CTS to monitor the systems. If my truck starts to regen at an inappropriate time ( like pulling into the driveway or into work) and I shut it down, I have noticed that the numbers on the CTS start counting down when I take off later in the day. The numbers will go down to about .85 then start going back up like it had done a complete regen. It only takes about 100 miles and will do a complete regen after this happens.
Any thoughts on this?

 

Sounds normal to me. After you shut down, the residual heat from the regen will continue to turn the soot to ash til it gets too low to do anything.

 

Stupid me, I never even thought of that. Thanks for the help.

 

On your shut down let it idle a few minutes. One to get the fuel out of the motor and secondly to max the heat in the dpf so the next regen is farther apart.
