Just got a B7 tfsi Quattro,it's got a noise every time I press the clutch,only does it when driving along and only makes the noise when clutch is pressed,previous owner said they all do it ,garage has put a 12 month warranty on it,it's not the usual thrust bearing noise more of a whaaa that does increase with speed when clutch is pressed.looking for a few pointers as new to this brand ,thanks

 

Could be the clutch pilot bearing/bushing since it increases when you press the accelerator with the clutch engaged.
