Hi, I’ve noticed a funny rattaling noise coming from my car when I drive without my foot on the accelator or just after I change gears. I can’t hear the noise with my windows up. It doesn’t effect the drive just annoying to listen to. It’s a Fiat Punto Evo 2010. Does anyone know what this noise could be? I’ve taken it to a couple of garages and they can’t diagnose it. Very strange
