One of the additional underlying issues which helps to make this problem the perfect storm is the pulley design. BMW has 2 smooth pulleys in tandem which really helps the belt slide off when it gets even a little oil on. I plan to call bmwna and see where that call goes I don't expect anything to happen but if anyone has any recommendations let me know. I would further like to clarify this issue identifies at least 2 complete design flaws. 1) the two non lipped pulleys in tandem which allows the belt to slide off 2) the ability for the belt to get pulled up into the engine.
