I've got a loose small bolt or something rolling around inside what sounds like my door sill area. It moves only 2-3 inches back and forth each time I accelerate and decelerate and sounds as though it's coming from the back side of the door sill closest to the side scoops. I've removed the under trays and checked under the car to see and found nothing. I've thoroughly checked inside the side scoop area by the intake, inside the car, inside the door, under the seats, etc. It's definitely coming from the door sill area. I was going to remove the door sill which is adhered with the foam tape from the factory to see if I can access a small compartment that a bolt my be in. For the guys that removed their door sills, is there access down inside the door sill compartment once the sill is off? I don't want to remove it if it's just a solid area. This is getting on my nerves.
