Subaru Forester 2010: "Garra Garra" noise

As we promised when you first contacted us regarding this problem we got in touch with Subaru and asked for an opinion on the noise on your car. We understand that they had a technical rep drive your car and talk to you about the problem, which the company says is “normal”. They have also agreed to change the clutch, despite the belief that it’s unlikely to fix the problem. It seems from what we have been told that the noise is a harmonic problem in the drivetrain and can’t easily be fixed by swapping parts.
