TaosX5- the intermittant reaction you got is probably correct. If ya start the car the lights do their self-check. If they move down a bit and then back.up, yer fine. Tweak the vertical adj whenever you want to change the aim. If the system none responsive, then you should have gotten a fault Msg. The bmw fault message for most things involving self-level and similar type systems is "$$$$$$$$"

Well, anyway if they don't get through the little self-check, then you are still back to "grab a Phillips and put 'em where you want 'em." You know, old school like.
