njsign, John from j- you are both right
John from j - I feel that hesitation you are talking about..it is a drag. Thanks for the info...will consider that FW.
In this case, it is a hesitation as in IT WONT GO! Feels like severe spark retardation or fuel starvation. Apply more throttle and it barely comes above idle. If you had to avoid traffic, you would have to get out and push it.
I think we are talking DSC Nazis here. BMW has a software quirk!
My theory: At such big slip angles (yaw) the yaw sensor inputs totally overwhelm the system and it just shuts everything down.
