I think N54 doesnt have that many issues in these production years anymore.
When this engine was new... 2007 or so it had issues... all the forum threads are from 2008- 2010 era. After that it kind of quiets down.
HPFP has had many revisions... last one is from 2011 to present day.
Injectors aswell are up to revision (index) 12 that came out in 2013...
ignition coils have changed over the years 3 times.

So a 2015-2016 car should have the latest injectors and high pressure fuelpump, better ingnition coils and so on from factory....

Im not saying it is bombproof... Things still can fail. But it is better.
