It's a problem with the N63 motor, which appeared in 6 series cars prior to 2013, and there seemed to be a cluster of this problem early in the 2013 builds, but it is an almost non-existent problem from 2014 on. Avoid the N63 motor like the plague - it is a POS, but the N63TU motor is a ultra-reliable beast so far!
This guy should replace his plugs and coils and give the car a chance. Whatever BMW did to update their coils seems to have eliminated the problem.
