Yes, my neighbour works nights and she says she does not hear it, but I am pretty sure people three streets away do…

I've just fitted one of these controllers as mine were stuck open all the time, probably a vac leak in the tube that runs all the way from the engine to the back of the car.
This unit has a built in vacuum pump so does away with that tube, and tbf it works brilliantly, how long for is anyone's guess
I just need to find an ignition live feed in the boot area now as the 12v aux socket there appears to be live all the time and I don't want the unit constantly powered up when the car is parked.
