Clutch noise

[jd's]

Hi all,

my first post, joined today, I've got a B6, 57plate, 4motion 2ltr diesel, 140 sport estate, still under warranty, at the mo got rather an annoying noise between changing gears, sounds like big end problem, but eminates from the clutch, rev the engine when the clutch pedal is half way and the car in motion, and horrible noise can be heard, rev the engine when the clutch fully depressed, nothing, dealers say they cant find anything, need sum ammo to throw back at them, anyone got any ideas???
