With my scanguage monitoring my spot load I can tell you on Highway at 60ish and above my diesel spot load slowly drops.

I think that "slowly" is the key word. My highway forays are short enough where the passive process can't get hold and sustain its efforts.Passive regen is not a myth. However, it only happens if DPF temp is 650F or higher. And, I ONLY see this happen if I'm driving on an interstate at higher speeds or if I'm towing a trailer. In those conditions where DPF temp is kept high, you can watch soot load decrease slowly as you drive.
How quick in your case?I think that "slowly" is the key word. My highway forays are short enough where the passive process can't get hold and sustain its efforts.
Actually, I'm shocked at how quickly the active regen clears the soot.
