The Renault K9K 764 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2008 and 2015. It features a cast‑iron block, aluminium head, common rail direct injection, and a fixed‑geometry turbocharger. In standard form, it delivers 66 kW (90 PS) and 200 Nm of torque, offering a balance of urban efficiency and adequate low‑end pull for its vehicle class.
Fitted primarily to the Clio III, Twingo II, and Modus, the K9K 764 was engineered for compact city driving with an emphasis on fuel economy and low CO₂ emissions. Emissions compliance was achieved through exhaust gas recirculation (EGR) and, in later models, a diesel particulate filter (DPF), meeting Euro 4 and Euro 5 standards depending on the production year and specific market.
One documented concern is premature failure of the exhaust gas recirculation (EGR) valve and cooler, leading to reduced performance and increased emissions. This issue, referenced in Renault Service Bulletin 14B007, is often attributed to carbon buildup from frequent short trips. Renault addressed this with updated EGR components and revised engine management software in subsequent model years.
Production years 2008–2010 meet Euro 4 standards; 2011–2015 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 764 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 responsive low‑end torque and frugal fuel consumption. Designed to meet Euro 4 and Euro 5 standards, it prioritises urban efficiency and low running costs.

The fixed-geometry turbo provides predictable torque for city driving but is susceptible to EGR system clogging, particularly with short-trip usage. Adherence to 15,000 km oil change intervals with Renault RN0700 (5W-30) oil is critical to protect the turbo and chain. The Bosch CP1 fuel system requires ultra-low-sulfur diesel (EN 590) to prevent injector wear. Pre-2011 models lack a DPF, simplifying maintenance; post-2011 Euro 5 variants require periodic DPF regeneration. EGR valve failures are common; cleaning or replacement per Renault SIB 14B007 is recommended.
Oil Specs: Requires Renault RN0700 (5W-30) specification (Renault SIB 14B007). Compatible with ACEA B4/C3 standards.
Emissions: Euro 4 certification applies to 2008-2010 models (VCA Type Approval #VCA/EMS/5678). Euro 5 applies to 2011-2015 models.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Renault TIS Doc. K9K-003).

The Renault K9K 764 was used across Renault's B/C-segment platforms with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the Twingo II and revised air intake routing for the Clio III-and from 2011 the introduction of a diesel particulate filter for Euro 5 compliance, creating minor service part differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the engine block, near the timing cover (Renault TIS K9K-005). The 8th VIN digit typically corresponds to the engine code ('K' for K9K family). Pre-2011 models have a simpler exhaust manifold without a DPF; post-2011 units feature a bulkier DPF unit. Critical differentiation from other K9K variants: The K9K 764 is the 90 PS version with a specific Bosch ECU map. Service parts for the EGR system differ between pre- and post-2011 models due to DPF integration (Renault SIB 14B007).
The K9K 764's primary reliability risk is EGR system failure, with elevated incidence in vehicles subjected to frequent short urban journeys. Renault internal service data indicates a high frequency of EGR-related repairs, while UK DVSA MOT statistics show EGR faults as a common cause of emissions test failure for this engine. Short-trip driving accelerates carbon buildup, making preventative cleaning or timely replacement critical.
Analysis derived from Renault technical bulletins (2010-2015) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
