Driving around in the city with all the traffic stops/starts and slow momentums my 2019 XF gets to temperature (on the digital gauge) and stays there, but within 10 minutes of dual carriageway or motorway speed the temperature dial drops down to the 'blue' on the dial and just hovers there. Also noticed the stop/start is not kicking in. How is one supposed to clear out the DPF if the temperature isn't correct.
Otherwise all things relative, car purring like the cat it is 👌
Any pointers really welcome, thanks.
