Looks like you're about to spend $15,000 on a new one box head to Pennsylvania and get that thing deleted

 

FL has a miles counter now for servicing the dpf.

Kind of like cars having miles counter for oil changes.

Call around for dealer pricing to have it serviced. Not all of them have the machine. Vegas WAS one of them. I don't know if they have one now but 3 years ago they were sending them out to a local shop. They wanted 3 times more money then Salt Lake who has a machine.

 

People are pressure washing them now with success. You have to have it cleaned and perform a forced regen. May be time to replace nox sensors too and clean the doser while it’s down.
