If not mistaken, auxiliary cooling fans remain on after vehicle shut down for a period of time depending on the engine temperature, so to cool down the turbos. Maybe the car is taking a quick temp check to ensure the fans don't need to be turned on again? What's crazy is that these cars these days with BMW Assist and the like are never really 'shut off' when parked.
