Reliability, common problems and owner reviews for the Mitsubishi Lancer 1.8 DI-D (4N13). Check this before you buy used.
The 1.8 DI-D (4N13) is Mitsubishi's own aluminium-block diesel with variable valve timing — economical and torquey, but a relatively complex modern diesel whose condition depends heavily on use and servicing. Short-trip city cars suffer DPF clogging and EGR soot; injectors and the variable-valve gear want clean oil. On a high-mileage, well-serviced motorway example it's fine; an unknown-history urban car is a gamble.
