I’ve baked filters, replaced doser, egr valve, dpf pressure sensor, egr pressure sensor, Nox and throttle valve. We ran a running diagnostics pulling a load, temps good and 0% ash. Soot levels drops nicely but go back up within an hour of driving. Thinking it might be over fueling? Kicked light for excessive regens as well. Anybody have ideas? Bad injector maybe? 2013 Cummins ISX15

some more detail on the history of truck? .. miles, year, make, model? etc.

2013 would imply an ISX CM2350?


also, when the cans were baked out, were they also de-ashed and flow tested, etc?. Did anyone do a maintenance reset procedure with insite when the cans were done to reset the ash and soot level counters inside the ecm too?

anyone check the decomp tube and DEF injector, etc?... ref: http://rawze.com/forums/showthread.php?t...07#pid1807

Any oil consumption? -- coolant consumption?

what is the avg. fuel mileage according to the pump and not the dash?

anyone do oil sampling to see how sooty the oil was getting?
