The Renault K9K 800 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2007 and 2018. It features a cast‑iron block, aluminium head, common‑rail direct injection, and a fixed‑geometry turbocharger. In its 64 kW (87 PS) form, it delivers peak torque of 200 Nm, providing adequate low‑end pull for urban driving and light loads.
Fitted to models like the Clio III, Mégane III, and Kangoo, the K9K 800 was engineered for cost‑effective, reliable urban mobility and…
Production years 2007–2010 meet Euro 4 standards; 2011–2018 models meet Euro 5 standards .
The Renault K9K 800 is a 1,461 cc inline‑three turbo‑diesel engineered for superminis and light vans (2007-2018). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver adequate low‑end torque for city driving. Designed to meet Euro 4 and Euro 5 standards, it prioritizes fuel economy and compact packaging.

The Renault K9K 800 was used across Renault's B/C-segment platforms with transverse mounting. This engine received platform-specific adaptations-different intake manifolds for the Clio versus the Kangoo-and from 2011 the Euro 5 models incorporated a DPF, creating minor parts 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 800 is generally robust mechanically, with a durable timing chain and bottom end. Its main weakness is the EGR system, prone to clogging with short trips. Euro 5 models add DPF complexity. With preventative maintenance, regular oil changes (5W-30 RN0700), and occasional longer drives, it can be very reliable for high mileages.
The most frequent issues are EGR valve/cooler clogging, DPF regeneration problems (on Euro 5 models), turbo actuator failure, and glow plug/relay faults. These are well-documented in Renault service bulletins, particularly for vehicles used in urban environments with low annual mileage.
This 1.5L dCi engine was widely used in Renault's smaller cars and vans. Key models include the Clio III (2007-2012), Mégane III (2008-2015), and Kangoo (2007-2018). It was also used by Nissan in the Micra K13 (2010-2017) as part of the Renault-Nissan alliance.
Aftermarket ECU tuning is common on the K9K-800 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, expect around 4.5 L/100km (63 mpg UK) on a combined cycle. Real-world figures vary: 5.0-5.5 L/100km (51-43 mpg UK) in city driving and 4.0-4.2 L/100km (71-67 mpg UK) on the highway. The Kangoo, being heavier, will return slightly less.
Yes. The K9K 800 is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal damage. Fortunately, the chain is very durable and rarely fails if oil is changed regularly.
Renault mandates the use of RN0700 specification oil, typically a 5W-30 synthetic. This is crucial for protecting the turbocharger, fuel injectors, and emissions systems. Using the correct oil helps prevent EGR and DPF issues and ensures the timing chain remains well-lubricated.
