6.4 regen

Hi
I have an 08 f250. Just had ford install a new oem 6.4 engine. The problem is it regens every time I drive the truck. Have had it back to ford a couple of times. Installed new DPF but still regens constantly never stops. I have tried driving it for 50 or 60 miles on highway just never stops. Any idea's? Ford had none.

Are there any codes?

Prior to my truck becoming an off-road race truck, I monitored the re-generation. It seemed to follow a very consistent pattern as if it was comparing Exhaust Back Presure Sensor to the DPF Back Presure Sensor, you might consider replacing those two sensors.

Ideas, but I don't know how valid they are. Have you changed the sensors? Have you tried a reflash?

EGT probes??? If one of the kids went bad, that would send it into regen space. What does your truck idle at? As Copper said, without it throwing a code...........We're lost.
