These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

It's not the rear seat backs or spoiler. Could it be the rear deck lid? It sounds like it is up high and more close to the inside. I don't believe it's the rear suspension....Any ideas, thanks.

POST 2Original post

SYMA Some time ago I had a knocking noise coming from the back. It turned out to be a loose speaker behind the grill.

POST 3 / ORIGINAL POSTEROriginal post

Thanks Scouser, I'll pop off the covers and check so I can eliminate that possibility. Do you know what is under the carpeted rear deck behind the back seats? I do not have the subwoofer there or anywhere actually. Thanks
