I was fixing the same issue today by putting in new fixing bow in while the old one was missing. I think 3 screws which hold the actuator in place are pretty rusted and 2 of them where broken so the whole assembly was loose. I put it in and the rattle is gone but I think It will come back soon. Does anyone know what kind of screws they are so I can get them and put them on. BMW needs to make these parts with good quality stuff I think. Pretty much all the bolts, nuts and screws are badly rusted below my f30.
