Isn't this the classic "bucking bronco" that happened with the E46? That car had a power button that was way too sensitive. It was worthless. The drive by wire throttle when on power and the car is cold is so sensitive that as you accelerate, your foot moves slightly back and lets off the gas. Damn thing is so sensititive, it is really hard to modulate. Just leave the power switch off when the car is cold.
