Here's a new/old problem. Had this clutch squeak when the car was new. The noise just sounds like a mouse squeak, and only happens when you let the clutch out with the gears engaged. There is no noise if you release the clutch with the car in neutral. It was fixed by re-routing the clutch cable or something like that. It's curious that the noise has resurface now the car is nearly 3 and with only <2 months of warranty left to run. I'll get the dealers to check the noise, when the car goes in next week for replacement of the boot catch trim.
