I took my '05 automatic 645 in for its first service, and in addition to getting the oil changed, I went over a list of issues. One of them was, when accelerating from a complete stop, there will (often) be a hesitation. It is as if the car does not take all the gas I give it. It starts off, backs off, and then accelerates normally from there. It's a slight effect but noticeable just the same. When I described this to the service advisor, he recognized the description and said he thought it might be a "software problem". He'd check it, and if I didn't have the latest software, he'd upgrade me. Well, I did have the latest software, and so he didn't do anything. The only other thing he could do was to work directly with the engineers at BMW. I questioned him further about this, and I believe he said that all 545's, 645's, and
745's are subject to this.Has anybody else heard of this and gotten resolution on this.
