Did they say what had caused the DPF failure?
so, does it inject more diesel fuel to run the engine a little hotter during a regen?
it depends on the year of the diesel vehicle how often they will go thru a timed regen versus.I’m getting like 13 hours between each regen on my new DPF. I don’t know if that’s normal or not. I never measured it before on the previous DPF. People say 24 hours between each regen but I’ve never seen that number and my manual doesn’t mention anything and on Cummins website they don’t publicly publish regen times other than generic 12-24 hour for some of the first generation of DPF’s.
13 hours and 500 something miles for me. In the past month i put over 2,500 miles on my 6.7 so I do a lot of highway driving with 3-4 minutes of idle for cool down when climbing the mountain.

FWIW there shouldn't be any way anything happening in the Adblue system ( aka SCR Selective Catalytic Reduction) that would effect the DPF simply because the Adblue system is after the DPF...Keep a close eye on things, usually a DPF failure is caused by another issue like a faulty sensor or an over dosing adblue injector etc.
It may be worth getting a genuine Mopar air filter fitted just in case the issue is not resolved. You don’t want to end up with a big bill all for the sake of an air filter.

That’s good. Plenty of the small diesel euro stuff has them after the cat and before the DPF so if you have an issue that makes the system overdose with adblue then you get a DPF core that’s completely ruined. I’ve seen it build up like a mountain off the DPF towards the injector it’s nuts.SCR is after the DPF so it should have no effect on it.
I think you have the parts confused.That’s good.

Are you thinking of the DOC?That’s good.

OK, so the Europeans figured out how to put 2 devices in one box. Funny thing is it still doesn't apply in this case.
I quite happy to admit it doesn’t apply in this case as I said above with my “that’s good” in response to youOK, so the Europeans figured out how to put 2 devices in one box. Funny thing is it still doesn't apply in this case.
