    Might reach out to this guy, I follow him on Facebook and he appears to be a wizard on the Cascadia's, he fixes one's that no Freightliner's can figure out.

    I am no DD expert but this screams electrical to me. Maybe wiring related to the aftertreatment?

    I agree with @JB7. Get into a good Freightliner or DD shop and follow escalation process for repeat failures
