A friend of mine with a 130i M has been struggling to get to the bottom of a strange throttle hesitation problem and had a tuner run diagnostics (pics up more than what most dealership machines can) and it turns out that the accelerator pedal module is fluctuating in terms of voltage at various throttle positions and causing this strange hesitation. Not sure if this relates to your car's problem...
