@dbs600: I'm pretty sure the aux water pump shuts down when you turn all (4 zones) of the climate controls off (when the display is turned off and all functions are shut down). I'll check it tomorrow morning when I drive the car again and post if it's different, but I'm pretty sure that's how it works...
