I've just had the same van in for a different fault, excessive white grey smoke, diagnosed as faulty injectors.
it had no dtc's for dpf problem, dpf pressure was good low and soot loading was 150% on this.

Live data if it helps

Last regen was 1700km

rpm 2645
temp 83
maf 159 kg/h
boost 203kpa
rail pressure 113.20 mpa
dpf pressure 2kpa
dpf saturation 151%
vehicle speed 97 km/h

Hopefully you have all the info needed now
