What Robin said: don't rev it when it's a-knocking, just let it settle on its own (30 seconds to 2 minutes) and report it to your dealer.
Also, try this: when you know the engine will go dead-cold (6+ hours), when you are parked slowly rev the engine to 3K, hold it there half a sec, then shut off power. I and a SAE engineer are convinced the root cause is with the S's variable oil delivery system*, and this shut-down technique seems to mitigate that nasty and scary rattle.
*justacoopers and justaclubmans dont have this feature, and they dont rattle.
