It may happen that the root cause is not one single item.

As mentioned before, I pick it up more with my right ear; but I have the impression that it comes from the rear while others seem to pick it up more from the front of the car.

If the cause are the bigger brakes, why is this not present in the car? It may happen that the resonance is created by the wind flowing in the bottom of the car, possibly pushed harder from the brakes and respective protection plates.

What drives me nuts is why the heck so many fantastic engineers in Germany are not able to discover the cause. The only explanation, mentioned before by someone is that this is not (yet) labelled as a major issue.

Meantime my car is still at dealership and no news whatsoever...
