VW 1.8 Auxiliary water pump

[Bluestream]

This engine has an electric water pump to cool down the turbo after yhe engine is shut off. Is the auxiliary water pump to run every time the engine is shut off, or just after coolant reaches certain temps? I have jumped 12V to the pump and it runs, but I have never heard it run on its own.

What sensor turns it on, and any way to test it?

If I had my service manual still I'd tell ya for sure but....

I remember it being a set time no matter what I think. Like 10 mins regardless of temp. I could be wrong though.
