I've had this rattle for the past several months on my 2007 TLS. It comes and goes, but is most prevalent cruising at highway speeds. It sounds like it is either coming from underneath the drivers side dash or the center console but is difficult to tell.

The link to a video is below. I'm cruising at 75 mph here. Turn up your volume and you'll hear a rattle throughout the video. Has anybody else had this rattle and been able to rectify the culprit? I'd love some insight into how to correct.

I am always on the lookout for rattles and noises. Truth be told - sounds like something in a cupholder or elsewhere... could be way wrong

 

Not from the cup holder... I've been hearing this one for months!
