When it goes away is done or should be drive around the block and let it complete the cycle? Should I take on highway and drive it? I going fill up the tank today because we are leaving for the Caribbean and won't be back to the end of the month and just going to sit while we are gone.
This is normal in the 6.7 PSD. The DPF cleaning can be either "active regeneration" by injecting diesel fuel into the DPF to increase temperature or by "passive regeneration" which is simply the sensors taking note that the DPF temperature from normal operation (usually towing) has increased to the level required for regeneration. You will get the pop-up on the display with either regen. No big deal. It's normal. The powertrain control module keeps track of all of this. A manual regen would only be required in the most unusual circumstances (too much easy driving for too long as an example).
DEF is injected into the SCR portion of the exhaust system and not associated with DPF regen.
Modern diesels are made to be driven... not abused but not driven by granny going to the store either. Towing is the best action you can do for your truck... no matter if a Ford, Cummins, or a Duramax.
Take your truck out to the interstate once and a while and give it a little "gas". You are doing it (and yourself) a favor! Today's diesels especially with items like the variable vane turbos on them can actually become clogged with soot if you don't put it to work now and then. Big money and I mean BIG money on turbo replacement.
