For last few months I have observed kit..kit..kit sound when I press the clutch completely down and hold it there with force. It happens when I press the clutch completely when in neutral. Sound stops even if I release the petal by even a few mm. Absolutely no sound of any kind after the gear is engaged or clutch is released. What may be the issue? Does it need immediate attention or can I live with it for some time (next scheduled service is in Jan-2016).
