This is a major issue for any future M5 buyer who expects to use it as an everyday car. Still can't identify if this is an outrageous "constructive specialty" of the car or just my problem. Here's an example of roads surfaces that make this sound loud enough to notice, it can be heard even from outside. The sound appears when the wheel falls into a pothole/railway/cobblestone taller than 3 cm in height.

Yep. Mine is definitely getting worse. Really sounds like a steel bar rolling around in the boot of the car. Hoping once I do the 2000k service I will be able to open up the exhaust flaps to drown out the sound ....
