Annoying clattering noise

[falanger]

So far the service dept has been unable to duplicate the noise, even after keeping my car several days, since it comes and goes randomly. In fact it took me forever to catch it on video.

Has anyone ever experienced anything like this, or have ANY idea what could be causing it?

Can you hear it emanating from inside the circular vents? Have you tried the difference with the vents fully closed? It sounds like something shifts and barely contacts a fan blade.

i guess merlin is right, sounds like a cable or any other object have contact with the fan blades while they rotating.

Yes, I thought can as well.
