Someone may be along to correct me, but I believe DPF regent is active between 70-90kph. At least that is what an indie garage told me while my car was hooked up. Certainly when I drive at that speed a regen is more noticeable with regards to a drop in mpg than if driving at 70mph and in a gear lower than normal.
