[A4] After-run pump, 30V

Verified that my car (2000 ATQ) does indeed have an after-run pump
(and module by the vacuum reservoir). I have the 8Z6 option for "hot
country," which appears to include a heavy-duty radiator, after-run
pump, and heavier cooling A/C.
Bentley seems to indicate that the pump, after MY 99, will run for 3
minutes if the vehicle is driven. I'm not sure if I've ever heard this
thing run. I got the car good and hot (oil temp at "11 o'clock") and
shut it off. No sounds from under the hood. Does it have to reach a
certain temperature and THEN it will run for 3 minutes? The coolant
temp always sits at "noon" (within a hair of it one way or the other
sometimes). Heat soak temperature readings, that is: me returning to
the car after it has sat for awhile, finds the needle barely past noon
(almost to the next mark).
Anyone have experience with an after-run pump? Any specs on what all is
included with the 8Z6 option?
