See http://www.sjmautotechnik.com/cooling.html#after  IME, with an 87C
thermostat installed, it runs after  most shutdowns (up to 10 minutes after
shutdown) here in sunny N.E. in the summer time. Almost never in the winter.
If you have a 80C thermostat, it may not come on except on the hottest days.
Note that it takes a while after shutdown for the pump and fan to come on.

I shorted the switch and the fan came on.  But, I have never heard it
startup after shutdown in over 6 years.  What temperature does the engine
have to reach before it turns on.  My temp rarely gets above the 4th line
on the water temp gauge on my 1993 S4.
