OK, I just got my first BMW. It's a 1999 Black/Black 540. It's beautiful, and the power is awesome! One problem... sometimes when slowing down, 9/10 times, it's pulling into a parking lot, it will just cut off. What the heck is wrong with my car??? ANyone else have this problem or know what to do. I heard it could most likely be a sensor or computer problem. (i.e.: DME programming) - what is this?
