Reliability, common problems and owner reviews for the Honda Civic X 1.6 i-DTEC (diesel). Check this before you buy used.
The 1.6 i-DTEC (the well-regarded Honda 'Earth Dreams' diesel, also in the CR-V/HR-V) is the frugal long-distance Civic X choice — refined, genuinely economical and one of the better small modern diesels. Standard cautions apply: DPF clogging on short trips, EGR sooting, AdBlue/SCR on later cars, and injector attention at high mileage. It's a chain-driven engine with a sound reputation; the main thing that hurts it is short urban-only use that never lets the DPF regen. For a motorway commuter it's a dependable, low-thirst engine — buy on DPF and service history.
