I've had an incredibly loud intermittent noise in my early F30 335i and after hours of diagnosis by BMW's support engineer, it turned out to be a plastic grease-stop cap that became loose and ended up inside the driveshaft! Driveshaft had to be replaced!
No, I’m afraid it has been separate stones. The dealer took out the second one from the front offside and showed it to me. It was a round rock about 1/2” in diameter.. Thanks for your input anyway.
