From what I've read this is a dynamic traction control failure. HTH. -Jim

I belive that is a fault in your ARS control module. Meaning your active sway bar control units. That fault can lead to many many issues. From alternator, to low battery charge. To steering angle sensors. I would check your powersteering fluid level and charge your battery if that doesn't fix it you will need to have the system looked at by a BMW specialist.
