Mine rattles from above the centre console, behind the side panel on the rear drivers side, front drivers side vent. It's been in today, and the dealer has "fixed" them all by refitting some of the panels and putting foam behind others. I drove out of the dealership, and within 100 yards I could tell they were all still rattling.
It's been in on three previous occasions for other things (ABS/ESP/SERV lights and engine mount), and every time I've mentioned the rattles. On every previous occasion they've said they couldn't hear any. This time they've just said they've fixed them! Hmmm.... I'd put my CD player on really loud to drown out the rattles, but the CD in there won't eject, and they'll only send it off for repair...... They won't replace it... I don't really relish the thought of having no CD/Radio for several weeks.
Fantastic!
