2009 IC FE Maxxforce DT Exhaust regeneration action "Bus 11AA" part 1

[@natehawkins2910]

So how do any particulates make it thru the DPF? A Cracked DPF? Or am I seeing DEF “steam” coming out (way too much DEF being injected) and it’s not smoke? Unburned fuel? Still don’t know how even that could make it thru an uncompromised DPF?

This bus doesn't have diesel exhaust fluid, it does the regen when the dpf gets full
