A ‘15 ISX 15 CM 2350X101 with 160k ‘15 Pete 579. Truck is constantly going into a “sort of” regen. Just a 750 rpm idle, getting warm and poor mpg. No hot exhaust light or anything. Just had the DPF cleaned and has had two forced regens with everything well to the plus side on the dealer laptop except for that it said it was trying to regen on the first one. Everyone scratching their heads. Gonna be back to the dealer in a few days and have them install a new wiring harness around the DPF and remove and check the DEF doser and the fuel injector doser. Anybody have any input on what else could be the issue? Thanks!
