Hello, I recently developed a noise under my '07 DB9 w/ almost 18k miles. It almost sounds like an extended "shushing" noise you would make w/ your mouth. It only seems to happen at idle and goes away when any throttle is applied. When it drops back down to idle, it will come back for 10-15 seconds, then disappear. I've only recorded the noise while in park. A/C and radio are off. I recorded this audio when the the car was almost at temp (sorry, I can't attach .flac files):

The engine fan kicks in at the 29 second mark, so that's not it. The microphone was placed under the driver's side door sill. The noise is not coming from the top of the engine.

Any help would be great!

Thanks.

 

Let me know if you figure it out. If it's coming from behind the front wheels then it sounds like the same noise my 07 makes during cooler months. It stops when the car warms up and doesn't happen as much in the summer.

 

Keep driving it. It will do one of 3 things.....get better.....stay the same........get worse at which point it will be easier to diagnose. This has served me well for decades.

 

I get this noise too on my 06 DB9. AM of Beverly Hills, who did the PPI when I bought the car and Robbie at Peninsula Motorsports who looks after my car now all say it's nothing to be concerned about.
