Sometimes when I turn my ignition on without starting the engine I hear a sort of electrical motor type sound that runs and runs. I can do the same thing another time and it isn’t running. This is in a cold car that hasn’t been run.
Sound eminates from front drivers side and can be heard through the wheel arch.

Could be the air suspension pump and/or self levelling, but in my experience that does stop fairly quickly.
My bet is on fuel pump.
Agreed, my Twinair does it too as soon as it's unlocked, a bit annoying if its not going to be driven.
