Nissan Qashqai
Renault-Nissan 1.5 dCi diesel engine — fitted in millions of vehicles. Fundamentally solid, but EGR valve and injectors are weak points.
Diesel duty done
110 hp diesel — low running costs, low fun level.
Engine Weaknesses 6
The K9K high-pressure pump can generate metal swarf that contaminates the entire fuel system. Pump, all four injectors, fuel lines, and tank must all be replaced.
Symptoms: Engine failure, starting difficulties, black smoke, metal particles visible in fuel filter.
The K9K timing belt can break prematurely if the injection pump is not correctly aligned. Misalignment causes the belt to fray at the edge and snap well before the replacement interval. Engine damage as it is an interference engine.
Symptoms: Belt noise, visible edge wear on timing belt, sudden engine shutdown
The K9K EGR valve clogs with soot deposits, especially during frequent short-trip driving. A stuck valve causes power loss and increased consumption.
Symptoms: Power loss, rough running, increased fuel consumption, check engine light with EGR fault code.
The K9K DPF does not regenerate sufficiently during frequent short-trip driving and clogs up. First problems often arise between 50,000 and 80,000 km.
Symptoms: DPF warning light, power loss, black smoke, regeneration cycles fail, vehicle enters limp mode.
The K9K charge air hose splits frequently, especially on older build years (FE0C version). Newer FE1C versions are more robust. The hose often tears at clamps or pinch points.
Symptoms: Sudden severe power loss, hissing noise under load, increased fuel consumption, check engine light.
The K9K camshaft sensor fails repeatedly from around 100,000 km. Sporadic starting problems and rough running are the result. Aftermarket sensors often last only a short time.
Symptoms: Sporadic starting problems, engine misfires, check engine light, occasional stalling
Vehicle Weaknesses 5
Tie rod ends and control arms wear above average on the Qashqai J10 facelift, just as on the pre-facelift. MOT testers flag these components regularly, especially from 80,000 km onwards.
Corrosion occurs particularly in the door shut faces beneath the door seals. On some production runs of the J10 facelift, factory sealing of the door hem flanges was missed, leading to early rust.
Brake discs and brake pads on the Qashqai J10 FL wear faster than on comparable vehicles. The MOT notes this regularly, especially on vehicles over 80,000 km.
Headlights, indicators and tail lights fail on the J10 facelift at an above-average rate. Defective bulbs and corroded sockets are common on older examples.
With age, door cards, dashboard and centre console develop rattles. Hard plastic quality is low and connections loosen over time.
