This is a video concerning repair on the engine rattle of death problem. Rumour it is for the dealers. I have come up empty in my search.

 

Well if it is for dealers only then you will not find it on line for a while as BMW/MINI are very very strict with letting that kind of stuff out to the public. If a tech lets it out then they will be fired. if the dealership knows the tech did such a thing and did not do all they can to prevent it then they could loose their franchise.
