Clutch Noise

Hi all,

I have brand new 2006 Honda Accord (Euro in Australia) with 3500 Km.
Perfect car but...

The clutch rattles most of the time and is at its worst at around
3000rpm when under engine braking i.e. down a hill. Noise dissapears
completley when I push in the clutch. Sounds like a metalic rattle,
with normal driving it's annoying when engine braking it's clearly
audible over the radio.

Anyone heard of noisy clutches? Dealer seems to think it's the torsion
springs within the clutch plate but won't comit (nor will Honda) to fix
it. So I'm stuck with a brand new car, everyone agreeing there is a
noise but no-one will fix it. They say wait until 10,000K sevice and
see if it gets worse.

Any ideas? Could it be something else?
