    Someone found a shop in Ohio that could take the One box apart and replace the SCR filters if they go bad. You could try Max Mileage made by Pittsburgh Power is a fuel additive that lowers the soot burning off temp in the DPF to some like 750F. It might help clean out soot by burning more off. The DPF filter could be full at around 500k.

    They also have thing called Diesel Force cleaning. It a foam they pump thru engine and emissions system and it supposed to clean out the soot. You can Google it. I remember Pittsburgh Power says it was like $2500 Other place beside Pittsburgh Power do the Diesel Force cleaning.
