Unfortunately, no.

It has hardly ever seen 4000 rpm at all, as there's really no point to it with these engines.
It may flow faster, but using more fuel means more new soot as well.
Some 350km / 220 miles later, first regeneration has occured.
That's way too early - it should be 1.5 to twice that distance.
