Dpf needs cleaning, maintenance code

[tree98]

If your numbers are good (lower than 3) I wouldn't worry about it at all.If not you could spray it out with water if you know for SURE your gonna demandate it. The water will wash away the rare metals and basically ruin the dpf but it will clean it out enough that you should be able to reset it and run it for now. Just remember if you do this and then decide not to demandate, you'll be buying a dpf.
