I asked my dealer yesterday if it could be the steering rack, but he said they tested that? However, I doubt they tried a different rack on mine, but who knows..
Btw, the dealer kept my car and gave me a 630i GT M-Sport as a loaner until my own car is fixed. Brand new (11/19 - 1.200 km so far). Drives fantastic :-D |

I guess it depends on what part of the rack is causing this. Some parts may be the same. Why should the eletric hydraulic motor be different for example? I can understand that the design of the rack may be different due to yours being FWD as well. I guess we'll find out at some point

Talked to my dealer today and they are waiting for respond from BMW, and regarding to them, they are not very hopeful. They think that it’s probably something that I have to live with😟 If so I’m going to make them to take the car back and I will choose an other brand!

If it is the rack, I'd expect it to change sound as you move the steering wheel a few degrees each way, at various driving speeds, and require changeable torque, to assist the movement. |

Any grinding sound, steering related, should be pretty obvious to any decent technician. I'm also sure some of you guys with the issue would sense if it is steering rack related. Vibrations should also change with steering loading, possibly also feel any changes thought the steering wheel, as well as the body. Also see my previous post. |

BTW, has anyone had a BMW 'field' engineer visit their dealer, to examine any of the problem vehicles? |

My dealer seems to lost interest in this. They have been told from BMW that they don’t have any solution and that they should give the car back to me. I refused that at first but since it is a company car, leased by an outsourced company I didn’t had any choice. I will probably let the leasing company make a reclaim. It’s really a shame how BMW take care of their customers!

I'm not sure, if a BMW engineer has been at the dealership (might have?), but I know the dealer is sending sound recordings/findings to BMW.

Since there are g21 with m-chassi that don't have this sound, so could the culprit be something else.
The car I know is silent has the same equipments as mine except m-sport brakes. I have driven a couple of G20s with m-sport brakes, and they were all silent, but they all had 19" wheels. Can culprit be the combination of 18" (or 17") and m-sport brakes? Is it only these cars that have this sound? Have anyone experience of a silent g21 with sport brakes and 17" or 18" ? |

I could buy into the theory, that the bigger M-breakes, combined with 17" or 18" wheels could create a resonance, maybe due to some compressed air, in the wheel arches which gets better on smooth and fresh asphalt. <Glaede> - do you know if our BMW dealer has tried with 19" wheels?
