They also found that there is noticeable play in the LHS bush of the central steering rod, which does cause a rattle on rough surfaces. Surprising as the car has only 2,300 km. Not a safety issue.
It must be TADTS (They All Do That Sir), as my M3W's steering rack has some play in the LH side as well. I was told by a person that should know at the factory to put some more grease in and refit the rubber boot. I did, it made no difference. It has been the same for the last 12,000 miles without a problem or change.
