Guys I have an '09 6.7, pulling a 30 ft 5er, have full deletes, CAT and DPF are removed but stock Muffler is still in place. While towing to Glacier I received an error of "DPF Full" See Dealer. It happened about 3 times in a period of 60 miles. I finally got to a rest area and reran the Smarty JR to Tow and cleared DTCs although there were none recorded. I didn't have any code problems the rest of the trip. The Truck was coming up on 20k... any ideas.

Ghost in the machine. Mine does this about every 2000 to 2500 miles. Clear it with the Smarty and dont worry about it.

 

Thanks Blake, I thought it was something like that as there didn't seem to be any problem associated with it.
