Perhaps BMW have not identified any particular issue yet. Even reading through this topic with the experiments and comments, it is still not evident if it is a mechanical component at fault, a specific specification, how the car is assembled, or simply a generated sound due to motion and speed. Is it airborne to the cabin, or a structural transmission? Can it be heard outside the car, via an open window, for example?
I still wonder at the scale of this noise problem. We are getting more tourings on the road as time moves forward, I wonder if we will see more users contributing to the topic, or more threads on the subject.
Joe's UK review on the M430i touring gets nothing but praise, for how quiet it is.
