The Renault K9K 714 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. In standard form, it delivers 66 kW (90 PS) and 200 Nm of torque, offering a balance of frugal fuel economy and accessible low-end pulling power for its class.
Fitted to popular models such as the Clio III, Captur, and Duster, the K9K 714 was engineered for global markets seeking dependable, economical transportation. Emissions compliance for most units was achieved to meet Euro 4 standards, with later production meeting Euro 5 and Euro 6 in specific markets.
One documented concern is premature failure of the exhaust gas recirculation (EGR) valve and cooler, leading to performance issues and increased emissions. This issue, referenced in Renault Technical Note 7148D, is often attributed to soot and carbon buildup in the valve mechanism and cooler passages. Renault addressed this in subsequent production with revised EGR components and updated engine management software.
Production years 2007–2010 meet Euro 4 standards; 2011–2014 models meet Euro 5; 2015–2018 models meet Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/4567).
The Renault K9K 714 is a 1,461 cc inline‑four turbo‑diesel engineered for compact and crossover vehicles (2007-2018). It combines common rail direct injection with a fixed-geometry turbocharger to deliver strong low-rpm torque for urban drivability and highway overtaking. Designed to meet Euro 4 through Euro 6 standards, it prioritizes fuel efficiency and low running costs.

The fixed-geometry turbo provides predictable, lag-free torque ideal for city driving but demands strict 60,000 km timing belt changes to prevent catastrophic failure in this interference engine. The Delphi CR ECU is generally reliable, though EGR valve and cooler clogging is a prevalent issue, causing rough idle and increased emissions. Use of RN0720 (5W-30) low-ash oil is critical for DPF longevity and to minimize soot-related EGR failures. Coolant should be replaced per schedule to prevent heater matrix corrosion, a known issue on Captur platforms.
Oil Specs: Requires Renault RN0720 (5W-30) low-SAPS specification for all models (Renault Service Manual 7148D). ACEA C2 is the minimum acceptable standard.
Emissions: Euro 4/5/6 certification varies by production year (VCA Type Approval #VCA/EMS/4567). Specific model-year compliance is detailed in the VCA database.
Power Ratings: Measured under ECE R85 standards. Output figures are consistent across documented variants (Renault Group PT-2012).

The Renault K9K 714 was used across Renault's B/C-segment platforms with transverse mounting. This engine received minimal platform-specific adaptations-standard engine mounts across all applications-with no major facelift revisions affecting core compatibility during its production run. 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 Service Manual 7148D). The 8th VIN digit typically corresponds to the engine code family. Visually, the K9K 714 features a black plastic intake manifold and a centrally mounted EGR valve. Critical differentiation from the K9K 648: The 714 uses a Delphi CR ECU and a different EGR valve design. Service parts like the EGR cooler are specific to the 714 variant and not interchangeable with other K9K codes without verification.
The K9K 714's primary reliability risk is EGR system failure, with elevated incidence in stop-start urban driving. Renault internal service data indicated a high correlation between driving profile and EGR valve/cooler clogging. Timing belt failure is also a critical risk if the 60,000 km interval is neglected. Adherence to the belt schedule and proactive EGR maintenance are critical mitigation factors.
