Auxiliary water pump after shut off?

[Forumlurker24]

Before on my GTI whenever I turned it off I could hear some kind of motor pump running, figured it was just a Volkswagen thing. Now that I'm at a dealer I heard a few other turbo Ford's making the noise as well.

My question is, are f150s supposed to have this ? I have not heard the noise come from mine which makes me slightly concerned

I had the same on my Jetta. I don’t believe there is one on the 3.5.
