So my 2022 JCW Convertible has developed a rattle. Mini service claims to have driven it and wasn't able to reproduce the issue. I find it difficult to believe they drove it because it's impossible to not hear. It sounds like a metallic, but I cant pinpoint it. I thought it was the speaker, but they claim to have taken the pillar and speaker apart and everything was tight.

Does anyone have any ideas?

 

Some rattles I've silenced: Loose instrument pod bolts, iPhone holder rattling, convertible roof 'hook' needing adjustment (connector on the side rail that locks to the windshield header), clamp for a garage door opener loose on the sun visor (a near identical sound), door lock cap loose, rear convertible trunk clamps not tightened, metal cup/ item in the cupholder or armrest, rear seats not fully locked in position, and passenger seatbelt loose and vibrating against the side of the car. To me, this sounds like it's coming from above in the windshield header, visor area, or convertible top, not the A-pillar.
