    What I see most often is the aftertreatment doser injector gets plugged up enough it simply won't get hot enough to do a proper regen.

    We see some trucks with fuel pressure that is slightly too high. There is a grey area where the pressure is too high and the ECM will not allow a regen, but yet not set a code. There is also no diagnostics for fuel pressure too high and none of our books say at what pressure the regen is aborted at. Max fuel delivery pressure is 120 psi. Max allowable aftertreatment fuel pressure 1 is about 135 psi. Any higher on either and regen will not start.

My company truck is a 2012 (272k) and just come out the shop again lol (egr cooler, valve, ect.) just kinda wanting to pinpoint when they'll trade it in or whether I should get a frequent sleepers card for a motel chain cause its gonna break again lol

    There are several different warranty packages you can buy. If it had basic warranty I think that is only 3 years.
