: Coolant circulation pump runs from startup on D2 S8?

Just recently, the Coolant circulation pump (I assume that is what it is, just f'ward of windscreen under heater air intake somewhere) has started to run from within about 5 seconds of starting my car, even with engine cold. Any ideas why. It runs continuously and until recently I have never heard it before. It is annoying on an otherwise v quiet car. What sensor triggers this?

Thanks
