Passive regeneration of the DPF is not bad at all. Well, besides the increased fuel consumption which would involve an active DPF regeneration, with all the environmental concerns surrounding the higher amount of fuel required, even if the ECM sets a leaner AFR in order to raise the EGTs and as a consequence the NOx emissions increase a bit, that ends up being not so awful at all.
