Creaking noises from the rear edge of the roof opening panel area, only when the opening panel in the closed position, during vehicle torsional inputs. This bulletin is a potential addition to the Service Instruction originally included in Service Action K117 (now expired) as this particular concern will normally occur while driving with the roof opening panel closed over undulations in the road such as, but not exclusively: drain covers, traffic calming measures, and uneven road surfaces.
