In order for a dpf to operate correctly it has to regenerate this is done by the pcm recognizing when the soot load goes above a set threshold. when this happens fuel is injected into the exaust system on the engine side of the dpf this superheats the dpf and burns out the unwanted ash and soot certain peramiters have to be met in order for this to take place or a forced regen can be carried out via ids. if your van is doing a lot of idleing or slow low rpm driveing the exaust stream can not gain enough temperature to keep the dpf clean, on the filter you will find sensors (the number varies could be 2 could be 3 ) and the 2 differential pressure sensor pipes the sensor wires are known to break at the harness connector where they join the main loom also the fuel injector/atomizer that sprays fuel into the exaust is known to fail both electricly and the fuel delivery- it can block so no fuel is sprayed into the exaust stream get the codes checked to see if the conditions are met to allow a regen to occur also a good blast up the road can raise the ex temp up enough to keep the dpf in good order
