Hey Guys, I was hoping to resurrect this thread. Was there any resolution to this? My wife and I bought an 04 X3 about 3 months ago and when I drive it, I notice a similar issue. It mostly happens in the 30-40 mph range, and strangely seems like it happens when I am coasting/decelerating downhill. When I describe the issue as "jerking" what I am feeling is a slight jerking, but I also see the RPMs fluctuate really quickly within 100-200 rpms of what it is coasting it..... so if it was coasting at 1000RPM, I see the needle go from 900 - 1100 really quickly a few times.
Any ideas whats going on?
Other than that the car drives great and it doesnt feel like the transmission is "broken". It is just "acting funny"
