It basically happens very sporadically, after getting into the car the car makes a grinding noise for about a second or so. Sometimes this happens several times a day, sometimes only a few times per week. But it is always after getting into the car, whether it be locked or unlocked, and happens typically 5-10 seconds after opening the door and always before pushing the start button. I had the dealer look at it and they claimed to have heard the sound and replaced some module, but the problem is still there. Mine is a 2018 540i M-sport.
