The Grandland X is a compact crossover built on PSA underpinnings; the diesel/manual pair is tuned for economy rather than sport. Diesel models have a DPF and EGR system that don’t like lots of short urban trips, and the manual means you should be mindful of clutch wear on high-mileage examples. Parts and dealer support are widely available in Ireland because Opel is mainstream, but check whether the particular car uses AdBlue/SCR or not as some diesel variants do.

• DPF behaviour — check for recent active regens and any persistent DPF warning messages (poor for short-trip use).
• EGR/intake carbon build-up — look for rough idling or loss of low-down power that suggests clogging.
• Clutch engagement and slipping — test from cold and on a hill for judder or weak bite (common wear item on manual diesels).
• Turbocharger smoke or lag — heavy blue/black smoke under acceleration or whistling can indicate turbo or oil-leak issues.
• Underbody and rear wheel-arch corrosion — check for salt-related rust in arches and around the trailing arms on Irish roads.
