I believe not.
The reason is because BMW specifies the N55 spark plug change interval at 60,000 miles which falls outside the 50,000 mile maintenance plan.
Now it's possible an earlier N20/26 F30 would have a spark plug change included in the scheduled maintenance because those initial spark plugs were spec'd for a 30,000 mile service life. (Not sure). However, I believe a revised spark plug was introduced which increased the interval to 60,000 miles.
