There have been numerous reports of DPFs resisting regeneration if they get too full, and requiring a manual forced regeneration. For the DPF to have filled up completely to the point where regeneration was impossible within only 65,000 miles suggests some major bad juju going on there. In addition, isn't there a Federal law requiring emissions stuff to warrantied up to 70 or 80 thousand miles or so? Or am I mistaken?
