MY 2017 D2 Momentum edition (ie the "simple" shape exhaust system).

Every now and again after a short local trip, we stop the engine to hear the fan running full-tilt with an apparent smell of fuel about the car.

As there's no reason for the engine to be that hot, and no sign of fuel leaking, I suspect it is cooking the content of the particle filter, to clean it up. My old (MY 2010) D2 1.6L drivE only regenerated the DPF when the car was running at speed, so this would be new behavior.

Am I safe to say this is the regeneration cycle, so ignore it, or should I have the car checked over by the dealer to see if there's a problem?

With thanks for your thoughts.
