Is this sound coming when you are at the end of travel of clutch, while releasing it in first gear? because lately me too having the same problem. This sound comes only when the car is moved from stand still, in first gear. Also when the clutch is kept half pressed when the car starts to move and then release fully after the car moves, this sound cannot be heard. Will it be an issue with the clutch? I have clocked almost 67K+ and my car is now >5 yrs old. Anyway planning to take it the service center as my regular check up is pending too. will post an update on the problem.
