Probably you are hearing the pump for the brake servo.

The air pressure in the fuel tank is slowly equalizing? Exhaust pipe cooling down and contracting?

There's a battery cooling fan, but it shouldn't be running continuously. Could that be it? From your other post about the beep when you brake, it sounds like a very confused PHEV. Perhaps a software corruption?

Permanent sound from the back+ beep when braking suggests an air leak in the brake servo circuit to me.

Would that flag up any warnings on the instrument panel, jaapv? And why would it run when the car is switched off?

I wouldn't know - I'll happily yield to a better explanation.

Is this while you are plugged in and charging?

The On Board Charger (OBC), Dc-Dc Converter are all under the luggage floor at the back as well as rear electric motor/generator and Rear Motor Control Unit (RMCU).

It may not be any problem at all. It could just be the PHEV doing its job.
