Well, you could always fix it the same way many have fixed it on the E53, like I posted above. Same concept of a tailgate, same rubber bumpers, same issues. There are more threads on the E53 because it has been around longer, more of them are out of warranty, etc.

Some owners had the latch replaced on '07 models under warranty to solve tailgate rattles.

Others found that the plastic flap on the inside rattles. You can find it the same way, riding in the back and seeing what changes the noise when you touch various panels. Description here.

And finally, you can always search for 'tailgate rattle', that works just as well in the E70 forum as it does in the E53 forum.
