V40 D2 two litre - How can I tell if it's doing a DPF regen?

[rx6180]

I wondered if anyone can tell me whether or not my 2015 two litre D2 V40 runs the electric radiator fan when it is doing a DPF regen?

I used to have a C30 DRIVe with the Ford/PSA 1.6 engine. Whenever the car was trying to do a DPF regen, I could hear the electric radiator fan running, the Start-Stop would disable, and the 'Miles-To-Empty-Tank' readout would drop quite a bit, until the regen was over. The radiator fan would also run during a regen if I turned the car off, locked it and walked away.

The V40 is harder to decipher. To start with, if the radiator fan is running for any reason, it will stop as soon as the car is turned off. Also, the fan is near silent and cannot be heard at tickover from inside the car. The 'Miles-To-Empty-Tank' readout is a bit erratic, and seems to go up and down fairly randomly on journeys to work, and the Stop-Start regularly ceases to operate for a few days.

If I see the 'Miles-To-Empty-Tank' readout drop by a fair amount on the V40, coupled with the Stop-Start ceasing to operate, I've taken to checking if the electric fan under the bonnet is running with the engine ticking over - but most of the time, it is not.

If the radiator fan IS NOT running, can I take it that the car isn't trying to clean the DPF? Or can a two litre D2 be trying to clean the DPF without it turning on its radiator fan?
