Even my punto (5500 Km) is making a tak(click) sound as mentioned by madhavnarayanan. But it never happened when car is cold and it is very occasional. Let me explain it in detail. Case 1 After covering a good distance (say 20-25km) when i change gear while completing pressing clutch and releasing gas pedal. It makes click sound. (But it is not always) Case 2 If i remove my feet from gas pedal (suddenly), it makes click sound, same with the case of sudden acceleration.
