We drive on the same side of the road as the UK, and my F11 Msport 535i does the same pull to the left. BMW have done the alignment and it came within specs. They rotated the strut and still no result.
I believe that the people who drive on the other side of the road experience the pull to the right and according to that posting on this forum, the problem was solved by some software update. Problem is my BMW dealer does not seem to be aware of that solution.
