The problem in this case is that the bearing bearings or the Damper pulley may fail . Remember, therefore, to stretch the belt to limit the risks or to swap it if it is too short. If after checking all thoses possibilities, you still detect a belt noises, read our article about timing belt noises on Renault Trafic which could maybe help you.
