The 2020 X‑Trail diesel with an automatic gearbox is aimed at buyers who want relaxed long-distance driving and decent towing ability. Be aware diesel-specific items (DPF/EGR/turbo) are the usual attention points on this age of car, and Nissan often used CVT/Xtronic automatics across the range — confirm the exact gearbox type and service history on the car you’re looking at. Parts and dealer support are common in Ireland, so routine servicing is straightforward.

• DPF condition and evidence of successful regenerations — ask if the car has had regular longer runs rather than only short trips (look for heavy soot or frequent warning lights).
• Automatic gearbox service history and shift quality — drive for smooth, consistent shifts with no hesitation or jerking; check under the car for transmission fluid leaks.
• Turbo and EGR soot or boost-hose leaks — watch for blue/black smoke under acceleration and listen for whine or lag from the turbo.
• If the car is marketed as 4WD, test centre-differential/4WD engagement and listen for unusual noises from the transfer case or front/rear differentials.
• Underbody and rear suspension condition — check for corrosion, sagging springs or signs of towing/overload around the rear subframe and towbar area.
