Can anyone help me. I am having a problem with my power folding mirrors on e53. When I press the button, they fold in but then pop straight back out again. I have tried a new switch, but still get the problem. I have noticed that the passenger side mirror is a little loose. Could this have anything to do with it and how do I tighten it? It is loose at the joint where the mirror folds. Thanks for any help, Im a new X5 owner and new to X5 world
