The Renault K9K 706 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2008 and 2015. It features a cast‑iron block, aluminium cylinder head, common rail direct injection, and a fixed‑geometry turbocharger. In standard form it delivered 66 kW (90 PS) and 200 Nm of torque, offering a blend of compact size and adequate low‑end pull for urban driving.
Fitted primarily to the Renault Clio III, Twingo II, and Modus, as well as the Nissan Micra K13 and Dacia Sandero I, the K9K 706 was engineered for compact city cars prioritising fuel economy and manoeuvrability. Emissions compliance was met through exhaust gas recirculation (EGR) and an oxidation catalyst, achieving Euro 4 standards.
One documented concern is premature failure of the dual‑mass flywheel (DMF), leading to drivetrain vibration and noise. This issue, referenced in Renault Technical Note MEC‑08‑012, is often linked to material fatigue under high torque loads. Later production runs saw revisions to the DMF design to improve durability.
Production years 2008–2015 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 706 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and city car applications (2008-2015). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver adequate low‑rpm torque and compact packaging. Designed to meet Euro 4 standards, it balances urban efficiency with basic performance.

The fixed-geometry turbo provides predictable low-RPM torque suitable for city driving but lacks the flexibility of a VGT. Strict adherence to 15,000 km oil change intervals using RN0700 (5W-30) oil is critical to protect the turbo and timing chain. The Bosch CP1 fuel pump requires ultra-low-sulfur diesel (ULSD) to prevent premature wear. The dual-mass flywheel is a known wear item; symptoms include clutch judder and drivetrain vibration, requiring replacement as a unit with the clutch kit per Renault Technical Note MEC-08-012. EGR systems benefit from periodic cleaning to maintain performance.
Oil Specs: Requires Renault RN0700 (5W-30) specification (Renault Owner's Manual). Equivalent to ACEA B4.
Emissions: Euro 4 certification applies to all 2008–2015 K9K 706 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output consistent across specified model range (Renault TIS Doc. K9K-003).

The Renault K9K 706 was used across Renault's B/C-segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Modus and specific ECU calibrations for the Twingo-creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the alternator (Renault TIS K9K-005). The 8th VIN digit typically indicates engine displacement ('6' for 1.5L dCi). Visually, the K9K 706 can be identified by its three-cylinder configuration and the 'dCi 90' badge on the rear of compatible vehicles. Critical differentiation from other K9K variants: The K9K 706 uses a specific ECU part number (e.g., 8200777777) and a fixed-geometry turbo. Service parts, particularly the flywheel and clutch, require matching the exact engine code due to variations across model years and platforms.
The K9K 706's primary reliability risk is dual-mass flywheel (DMF) failure, with elevated incidence in vehicles subjected to frequent stop-start driving or hill starts. Renault internal service data indicated a high replacement rate for this component, while owner reports frequently cite clutch judder as the first symptom. Urban driving cycles increase stress on the drivetrain, making proactive replacement at the first sign of trouble critical.
Analysis derived from Renault technical bulletins (2008-2015) and owner-reported failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
