Excessive Regen (non stop)

[MCRENT]

You have to get Cummins insite.. you are pissing against the wind without it.. not sure which version you have to get with the 2018 year engine or truck but that is the 1st thing you need to do. Or take it to one of the recommended mechanics on this forum. In my experience if you doing a constant regen you have leaking injector or loose quill tubes or a possible electrical issue tricking the computer into thinking you need a regen. At 600 K it s a good idea to just change all the sensors on the engine if they have not been done lately just to make sure they are not sending bad info to the computer..
