I have heard that this is an infamous rattle. I have started to get sick of it and cannot figure out how to solve the problem. Anyone have a quick fix?

My X5 is in for service at the dealer. I figured I could tell them to fix it while its there but the noise magically stopped right before I got there!

Thanks!
