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…
Production years 2008–2010 meet Euro 4 standards; 2011–2015 models meet Euro 5 compliance depending on market .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 764 is generally robust mechanically, with its timing chain designed for the engine's lifespan. Its main weakness is the EGR system, prone to clogging on short trips. With proactive EGR maintenance and regular oil changes using RN0700 spec oil, it can be a dependable long-term engine.
The most frequent issues are EGR valve/cooler failure, turbo actuator faults, and glow plug/module problems. Oil leaks from the rocker cover gasket are also common as the engine ages. These are well-documented in Renault service bulletins like 14B007.
The K9K 764 (90 PS dCi) was primarily used in the Renault Clio III (2008-2012), Twingo II (2008-2014), and Modus (2008-2012). It was also fitted to the Nissan Micra K13 (2010-2015) as part of the Renault-Nissan alliance.
Aftermarket ECU tuning is common on the K9K-764 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Excellent for its era. In a Clio III dCi 90, expect combined figures of ~4.5 L/100km (63 mpg UK). Real-world economy is typically 50-60 mpg UK, depending on driving style. Its strength is low-speed, urban fuel efficiency.
Yes. The K9K 764 is an interference engine. If the timing chain were to fail (though rare), the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable.
Renault mandates the use of RN0700 specification oil, typically a 5W-30 synthetic. Using the correct oil is vital for protecting the turbocharger, maintaining chain lubrication, and ensuring the DPF (on later models) functions correctly.
