Ive noticed it to sound like a loud fan.
Mostly present when in sport plus throttle setting. I think its the extra cooling on the radiators but goes away quite quickly after stopping at a light.
First i thought it was the turbos spinning down ( ball bearing turbos usually make this sound when spinning down).
If anyone knows what is causing this sound, id like to know..
