Reliability, common problems and owner reviews for the Mitsubishi ASX 1.8 DI-D (4N13). Check this before you buy used.
The 1.8 DI-D (4N13) — Mitsubishi's own aluminium-block VVT diesel, economical and willing, but a complex modern diesel whose health is all about use and servicing. City/short-trip cars clog DPFs and soot up EGRs; injectors and valve gear want clean oil. A documented high-mileage motorway example is fine; an unknown urban one is a risk. Diesel only pays for high annual mileage.
