Sunroof rattle when sun shade open

[Bruno_s4]

I know we have discussed various rattles in our cars (especially as they get older) but I can't seem to track down a big one for me.
When I drive with the sunroof sun shade open I get a pretty steady buzzing rattle from my music.
But when the shade is closed the rattle is gone.
Has anyone else experienced this and repaired it?

Thx

I have a S5 with different sunroof, but it used to have the same issue (rattle when opened). Dealer replaced the sunroof guide under warranty. Would've cost around $1500 if out of warranty.

Does the sunroof/sunshade also rattle when the sunshade is open and you do not have your music on? With the sunroof open, can you access any of the sunroof's track's mounting screws from the top to see if they can be tightened? I don't have an aftermarket sub and generally don't listen to music that loud so have not experienced that rattle or buzzing. Although I put my 2-year old Michelin PSS summers back on over the weekend and can definitely hear them humming a bit - maybe I need to turn the music on louder!
