I'm no more certain what the result of the sound is but either valve clatter or direct injectors appears to be the general forum consensus.
For me the exact clatter kicks in a few minutes after starting up the car. Prior to then it hums pretty quietly.

When cold AVCS is disabled. Once it crosses the temperature threshold it enables AVCS and you will hear a distinct change in the sound of the engine. The time this takes varies depending on how long the car was sitting before cranking. If you stand in front of the car long enough you will hear it switch and it's very noticable. It goes from sounding like crap to really crappy.
