The ventilation system makes a few weird noises when shutting down, also the cooling fans can still run when switched off. Apart from that some of the newer cars have weird noises when the infotainment shuts down but can’t recall that on my 8V.

Cooling fan (depending coolant temp)
Electric water pump
stepper motor range adaptation for throttle body or part of PCV (can’t recall which)

All Perfectly normal.

Enjoy the new car.
