DPF cleaning on a 2017 Peterbilt with a Paccar Mx-13

[@PaulyP420]

I'm dealing with what I think is dpf filter issues on my 17' 337 paccar px-7 new egr. New outlet nox sensor. Had fault code spm4364 fmi 31. Ran fine for couple weeks after and then red stop engine light came on and now have dpf fault codes

How long did it take you from start to finish to complete this task?

Maybe about 1 hour - 1 1/2 hours of my time. DPF baking comes back the next day. And computer work with forced regen about an hour.

Dumbest fn thing I have ever experienced. A highly corrosive fluid being sprayed into and engine and components. Thanks EPA.
