RC,
I don't hear the noise at all. The clutch "chatter" is a severe vibration that shakes the entire car at low speeds while the clutch is being slowly let out. It's unmistakeable but not present when cold or if you rev it up a bit while letting out the clutch. I'm sure it will be fixed and hope it's a fluke and not something a lot of 997's will experience; not an rms issue or cayenne turbo lurch problem (main reason I parted with the suv).
