Hello, I hope someone can help me here. My Smart 451 EZ 12/2011, ~40tKm, 61hp mhd squeaks or chirps since recently. The noise changes with the speed and (in my impression) also with the load. I could not locate it 100% yet, but I am quite sure that it comes from the rear right, so from the engine. I looked under the car and took photos of the two belts, which can be seen without disassembly of parts (unfortunately I have no ramp or pit to be able to look at the thing better). I noticed that the pulley that goes up doesn’t seem to sit right (easy overstanding outwards I can feel) and is also slightly frayed on the outside. Can someone here make a statement from the pictures, whether something is not ok and thus the cause for the noise can be? I don’t have the car yet very long and also guarantee, however, the dealer is a little further away. In this respect I would like to help myself or know a good way to do it in the room?
