Issue
The aftertreatment diesel particulate filter (DPF) design was changed. Because of this physical
design change, service locations questioned if the aftertreatment DPF had a manufacturing
defect and were unsure if the aftertreatment DPF should be used. This document displays the
physical difference between both the new and previous aftertreatment DPF designs.
