Are you saying that the DPF is cleared every time I give the car a good long blast!
I think the old MPG would suffer quite dramatically (which it isn't).
Surely, there must be some upper parameters within the Engine Management System which trigger an auto regeneration and I assume that if these are not met, then even a blast down the motorway would not necessarily achieve regeneration.
