It appears that operating trucks equipped with DPF are providing the same headaches that previous technologies provided in the early days of operation. However, the kind of problems differ this go around.
In talking with dealer service personnel, engine service personnel, and fleets the problems all seem to relate to education and not necessarily equipment failure. That is not to say there have not been component failures, but it appears that they have been minimal. Of course, it depends upon whom you talk when it come to the education issues. The common thread among all persons contacted points to the driver and his understanding of the lights and switches. It would be helpful to all concerned if we could hear from fleets going forward.
