Strange noise from dash at exactly 60mph

[royp4]

I have a 2003 996 carrera cabrio. Recently it has developed a rattle or possibly a warning buzzer at exactly 60 mph. Could this be related to the limiter setting? Any help would be greatly appreciated. Thank you in advance

No, but it very well could be the "speed gong" associated with the on board computer.

I have disabled the activation option but to no avail. I'm at a loss. Any suggestions welcome. Thank you.

Driving wind can also make such a noise, tape the seems from the front trunk to the other body parts with duck tape, the seals around the front windshield, the seams from the convertible top to the windshield(s) etc., do test drives to locate the noise. Of course, it would be easier to use an ultrasonic device if possible.

Thank you so much RFM. I was so convinced that the noise was coming from the speakers that I didn't consider any other possible solutions. As you so kindly suggested, it was wind noise from windshield gasket. Gasket replaced and noise gone. Again I thank you much.

You can also look for a shop with a system called an “electronic ear”, which uses six separate noise sensors mounted at various parts of the car that can quickly triangulate an isolate the location of the sound.  We have successfully use this system to locate very hard to locate sound sources.

Glad that it is resolved
