I started my L this morning and I had a really loud vibration sound that sounded like it came from the air filter so I tapped the gas and it quit. Then I heard another noise that sounded like a belt noise and I got out and popped the hood and listened and it sounded like it was coming from the belt that is attached to the supercharger. Has anyone had these noises and does anyone know what they could be and there cause? thanks in advance for any help.
