Disadvantages, breakdowns and problems of the N54
The main problems of the engine are associated with the direct fuel injection system.
Injectors and high pressure fuel pumps may require replacement much earlier than 100 km of run
In engines before 2010, the low pressure valve often failed.
Not the biggest resource here is also a pair of Mitsubishi TD03-10TK3 turbines
A newfangled electric pump tends to fail at the most inopportune moment
