This is the J11-generation Qashqai (common in Ireland) and many 2016 diesels use Renault-sourced diesel engines with a manual gearbox — mechanically simple but fitted with a DPF and EGR. Expect good parts availability and strong demand on the used market, but watch for DPF/EGR/turbo carbon issues if the car has been used for short urban trips; also check clutch condition on a 10‑year-old manual. AWD was an optional extra on some models, so confirm drive layout if you need traction.

• DPF and EGR behaviour: look for frequent regeneration events, heavy smoke on acceleration or the dash DPF warning (clogging is common if mostly short trips).
• Turbo condition: test for boost build-up, unusual whistle, rattles or oil leaks from turbo/intercooler pipes under load.
• Clutch feel and judder: check for slipping, a high biting point or judder signs (dual‑mass flywheel symptoms can be costly to fix).
• Manual gearbox operation: ensure gears select cleanly (no notchy synchro in 2nd/3rd) and listen for bearings or grind under load.
• Underbody and rear wheelarch seams: inspect for corrosion around sills, rear arches and suspension mounting points and check for worn suspension bushes/knocks.
