another e owner who had a similar noise in his car. He had traced it to the plastic casing around the base of the rear view mirror adjacent to the windscreen, he gave it a wiggle and it was OK.
Unfortunately my wiggling and moving the cover didn't make the buzzy rattle stop - at one point it seemed to make it worse. I even tried squeezing something between the cover and the windscreen, but that didn't make any difference.
Hoperfully I'm not speaking too soon, but I think I may have stopped my car's rattle - it's been rattle free for 5 days. Fingers crossed!
What I did to fix it (I think) was to press up on the cover, roughly in the middle, until I felt the cover making contact with something solid. After a brief application of pressure I released it. It has not rattled since. I hope it's not just a coincidence (it stopped rattling for a few days once before).
