Mine sounds worse on overrun and sounds like gearbox whine. I’ve changed my gearbox oil twice before I noticed that turning off the AC stops the noise.

I posted a thread regarding AC noise, I finally fixed it and car has been silent ever since. New silencer pipe and correct gas and oil amount was final cure. The noise it made would have you thinking the compressor bearings were about to come say hello.
