Funny mine just started to do the same thing this week, and if I'm not mistaking yours and mine got built around the same time (June). I have about 2,000 miles on mine and up to last week there was no rattle at all....2k5GTC said:
I'd be also curious to find out if othrs have the same issue.
BTW, I did a test this morning and it seems that if I leave my driver's window slighltly open it's not doing it as much, but I need to confirm this !
