The Renault K9K 718 is a 1,461 cc, inline‑four turbo‑diesel engine produced between 2007 and 2018. It features a single overhead camshaft (SOHC) design with 8 valves and common‑rail direct injection, delivering outputs around 66 kW (90 PS) and 200 Nm of torque. Its compact, lightweight architecture prioritises fuel efficiency and strong low‑end torque for urban and regional driving.
Fitted to popular models like the Clio III/IV, Captur, and Duster, the K9K 718 was engineered for economical, low‑maintenance motoring. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), allowing most units to meet Euro 4 standards, with later builds conforming to Euro 5 and Euro 6 depending on specific market regulations.
One documented service concern is premature failure of the high‑pressure fuel pump, particularly in higher‑mileage examples or those exposed to poor‑quality fuel. This issue, referenced in Renault Technical Note 4501 (superseded by 4501B for this variant), is often attributed to contaminant ingress or lubrication failure within the pump assembly. Renault addressed this by revising fuel filter specifications and recommending stricter fuel quality controls in subsequent service updates.
Production years 2007–2010 meet Euro 4 standards; 2011–2015 models meet Euro 5; 2016–2018 models meet Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/4567).
The Renault K9K 718 is a 1,461 cc inline‑four turbo‑diesel engine engineered for compact hatchbacks, crossovers, and SUVs (2007-2018). It combines common‑rail direct injection with a simple SOHC 8-valve layout to deliver strong low‑end torque and exceptional fuel economy. Designed to meet Euro 4 (and later Euro 5/Euro 6) standards, it balances everyday performance with low running costs.

The fixed-geometry turbo provides strong low-RPM torque ideal for city driving but demands strict adherence to 20,000 km oil change intervals and high-quality low-sulfur diesel to protect the common-rail system. Renault RN0700 (5W-40) oil is critical for its high-pressure fuel pump lubrication properties. The timing belt is an interference design; failure causes catastrophic damage, making the 120,000 km replacement interval mandatory. Fuel filter changes every 40,000 km are essential to prevent pump failure per Technical Note 4501B. Post-2015 models feature updated DPF regeneration strategies.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault Service Manual 70B). ACEA B3/B4 or equivalent diesel-specific oils are acceptable.
Emissions: Euro 4 certification applies to 2007-2010 models, Euro 5 to 2011-2015, and Euro 6 to 2016-2018 models (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Renault TIS Doc. K9K-07).

The Renault K9K 718 was used across Renault's B and crossover platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Duster and revised intake manifolds in the Clio IV-and from 2011 and 2016 the adoption of emissions hardware for Euro 5 and Euro 6 compliance, creating minor service part differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault TIS K9K-07). The 8th VIN digit typically indicates engine displacement ('5' for 1.5L). Pre-2011 engines have a silver cam cover; 2011-2015 units may have a grey cam cover; post-2016 units have a black cam cover indicating Euro 6 hardware. Critical differentiation from K9K 649: K9K 718 uses a higher-output calibration and often includes a DPF on post-2011 models.
The K9K 718's primary documented concern is high-pressure fuel pump failure, with elevated incidence in high-mileage or fuel-contaminated vehicles. Renault internal reports noted this issue across the production run, while owner feedback often cites EGR valve and DPF clogging as common emissions faults. Neglecting the 120,000 km timing belt interval is a critical risk, leading to total engine destruction.
