I own a 2005 X5 4.4. It has about 12k miles on it. About a month ago I noticed that if I came to a stop sign, stopped briefly, and then continued, that it would sometimes (4 times!) clunk as if the flywheel were catching up with the tranny, or something like that. So I took it in to my dealer, and he just called to say that the tranny needed to be re-programmed, and that the situation I described is not unusual.

hmmmmm!
