Verso 2,2D from 2008 – Short distances

Hello! My parents drive your car mentioned above, since they drive less and less long distance with it, we had now already 2x the case that the DPF was clogged and the car was no longer mobile. cost now already 2x 140 Euro to burn the manually free. I wonder if it still makes sense to keep the car, or rather to switch over to Verso or Verso-S with petrol, because the benziner the short distance is still more important. What would you suggest? there is no possibility To shut down the DPF somehow, to program out? Make the car in your eyes still meaningful? Is the 140hp diesel. Danke for a few opinions. lg
