Fellow 6.7 owners, In April, DW & I purchased a 2015 F250 with the 6.7 diesel. Gotta say I love how it tows our trailer. Goes down the road like it is not even back there. My question is about...
I don't have that particular vehicle, but the one I do have that has a DPF, does the same thing. The regen is triggered by a sensor that measures the back pressure of the DPF, which increases as it fills with soot. When the computer sees the DPF is getting full, it regenerates. You have no control over it. And once a tank of fuel is about right. Maybe twice.
