Hello all. I have a 310k with 2300 hrs. The machine will only regen to about 38% during a parked regen. The machine will kick itself out of regen saying unable to maintain high enough temperature. The engine temp itself its in the normal operating range of where it hovers during normal use before the parked regen was started. The soot level was at level 6 before we tried to perform a parked regen. The dpf was removed and cleaned thinking that it was clogged and preventing a proper regen cycle. The code for soot level to high has cleared but still left with the temperature issue. Possibly a bad egr valve preventing the needed temperature increase needed ? Any thoughts would be greatly appreciated.
