Radiator Fan running
Is it normal for the radiator fan (I assume it is the radiator fan) to run after turning off your car? I have a 2015 A8L 4.0T. Now if I restart the car and turn it back off the fan stops.

Yes, my S8 after runs the fans commonly, even on a moderate day. D3 W12 only did when it got quite hot. Glad it does given the amount of heat under hood at shutdown. Those of us with D3 W12's saw a number of parts get pretty heat soaked over the years underhood, especially toward the back.

Happens on my S8+ pretty much every time I turn the car off, unless I have barely driven the car. It was also a surprise for me initially, coming from a V8 M3 which pretty much never did it.

It has a lot to do with the fact the turbos are under a plastic cover on top of the engine. There is a temp sensor under there and if it thinks it might get hot enough to melt the plastic cover it runs the fans.
