Hi
@marjon,
Thanks for taking the time to reply.
I don't see how the driver is at fault when the car is driven on a motorway for over an hour, yet passive regeneration does nothing to the increasing soot level.
Here, I present three more examples of my car not being able to perform an effective passive generation despite me driving at speeds above 70 mph.
Drive #1:

Drive #2 (the soot level slightly dips halfway through, thanks to the exhaust gas temperature spiking above 500ºC), but only the active regeneration at the end of the trip clears the soot.

Drive #3 (continuously driving at 80 mph, yet not a single dip in the soot level, despite the continuous passive regeneration):

How else is a car supposed to be driven, if not for over an hour at speeds above 70 mph? The DPF is clearly unable to do its job, thanks to the car's faulty design. Land Rover mounted the DPF way too far from the engine, and thus, the hot exhaust gas cools down just too much as it enters the DPF.
