I assume that the noises you hear are high pitched electronic noises? There will be some clicking noises as well. The throttle body will stay partially open to aid in starting until the car "goes to sleep". I mean when the CAN bus shuts down. You will also notice these sounds in the morning when you unlock or open your door.
As for the noise you hear after the engine shut off, that's most likely the secondary coolant pump that keeps circulating coolant until a certain temp is reached. This prolongs turbo life.
Hope this helps

what about when I stop or when I turn off my S3 there is strong metal clunking sound (very short in its nature and happens very infrequently, like twice or three times a minute and then stops)? Most my previous cars had similar noises but there were more frequent and less louder.
