Pinpoint Test C : The Roof Opening Panel Rattles: Notes

Normal Operation and Fault Conditions 

When the roof opening panel glass is completely closed, it is flush with the roof panel. All components should be secured correctly. The roof opening panel system is made up of many components that require specific torque specifications and correct installation in order to avoid any NVH concerns. Over time, components may become loose or damaged, fasteners may become loose, sound insulating material may wear out and foreign material may collect in the roof opening panel frame. It is possible that one or more of these conditions may lead to a rattle concern in the roof opening panel system.
