I make lots of short journeys, how will this affect my DPF?

The particles are trapped on the walls of the DPF, stored and continually disposed of. We call this process 'regeneration'. The DPF system needs the car to be driven at a constant road speed so the regeneration process can be completed successfully. Lots of short journeys, and trips that involve stop/start traffic, may cause the regeneration cycle to be unsuccessful. A single, longer journey may be all that is required for regeneration to be successfully completed.

If your typical driving profile involves short trips in heavy traffic, you may wish to reconsider your choice of car, and may prefer to choose either an electric or hybrid model or one with a small petrol engine instead.
