The 1.9 dCi (F9Q — the Renault-sourced common-rail diesel shared across the Mégane/Laguna/Scénic, and the same family that wears Suzuki's DDiS badge on the Grand Vitara) is the economical long-distance Primera. It's a proven high-mileage engine but carries the F9Q cautions: injector wear (the classic dCi item), turbo and EGR attention, swirl-flap and the timing belt (do it on schedule). With clean fuel, on-time belt and a healthy injector set it's a dependable 250k-capable unit; buy on belt and injector history.
