When you put your car into M Mode the circle with a M, lights up on the dash, my question is, how does one get the car into M Dynamic Mode? (MDM on the dash)
It's is configurable under M settings, basically where you can change the traction control setting to on/off or MDM, if you cannot find the option then you may not have an M-Dynamic model.
MDM refers to traction control. if you press the traction control button once, it will not engage MDM traction like a 1M.
with the I Drive, you can configure if you want MDM traction on, Traction off, or traction on, when u push "M".
