Most 2017 Capturs with diesel use Renault’s small dCi engines paired with a manual gearbox — economical on long runs but they don’t like lots of short trips because the diesel particulate filter and EGR can clog. Clutch wear and turbo hose condition are common items on higher-mileage cars; parts and servicing are widely available through main dealers and independent garages in Ireland.

• DPF and EGR condition — ask if the car has had motorway runs and check for recent DPF regenerations or warning lights (diesels used only for short urban trips often clog).
• Clutch feel and gearbox synchros — test from cold and under load for slipping, catch point, or crunching between gears.
• Turbo and intake hoses — listen for whistle/lag and check for oil-in-let or smoke under hard acceleration (signs of turbo wear or leaks).
• Underbody, rear arches and suspension bushes — check for corrosion and worn rear bushes, especially given Irish salt and age.
• Fuel-filter/recent service history — confirm fuel-filter changes and timing of major diesel services (fuel filters are a common maintenance item).
