Hello, my wife’s vehicle is a Clio built in 2001 with 75 hp and has been hearing a strange sound for two days. It sounds like a grinding bearing. The box has a steering chain or? I would have typed on the timing belt but he didn’t… The noise is also in idle mode. As soon as you get some gas it hisses briefly (half a second). The noise can also be heard in driving mode in the vehicle. When I stand in front of the car it comes off Do you have any idea what that could be?
