DPF differential Pressure problems

[joed2323]

Has the dpf filter/do ever been removed? Inspected or cleaned?

Alot of times just changing that sensor doesn't help. Its definitely worth a shot.

Ive had dpf filters cleaned before and I swear the dealership doesnt do a good job cleaning them.

This one truck had numerous differential pressure codes, we had the dpf and doc cleaned and still the same codes. Finally I.said f it and replaced the filter with a brand new dpf, haven't had problems since.

Im not sure why getting the dpf filter doesn't always work. But starting to think just replacing it with a new filter is the way to go instead of constant nagging diff psi codes.

Maybe someone with more knowledge can explain why getting the filter cleaned by a dealership doesnt always work
