The Renault K9K 752 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2007 and 2018. It features a cast iron block, aluminium cylinder head, and a single overhead camshaft (SOHC) with 12 valves. Equipped with a fixed‑geometry turbocharger and common rail direct injection, it delivers 66 kW (90 PS) and 200 Nm of torque, offering strong low‑rpm pull for urban drivability.

Production years 2007–2009 meet Euro 4 standards; 2010–2018 models meet Euro 5 standards .
The Renault K9K 752 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and compact MPV applications (2007-2018). It combines a robust cast iron block with common‑rail direct injection to deliver accessible low‑end torque and frugal operation. Designed to meet Euro 4 and Euro 5 emissions standards, it prioritises cost‑effective ownership and urban efficiency.

The Renault K9K 752 was used across Renault's B/C platforms with transverse mounting. This engine received platform-specific adaptations-different engine mounts for the Kangoo versus the Clio-and from 2010 received an updated EGR system for Euro 5 compliance, though core mechanical components remained interchangeable. 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 752 is generally robust with a simple design. Its main weakness is the EGR system, which clogs easily on short trips. With regular longer drives to clean the system and adherence to service schedules using RN0710 oil, it can easily surpass 200,000 km without major issues.
The most frequent issues are EGR valve/cooler clogging, glow plug failures, and leaks from injector seals or fuel return lines. Turbo actuator problems and associated vacuum hose leaks are also common. These are well-documented in Renault service notes.
This 1.5L dCi 90 engine was used in the Clio III (2007-2012), Mégane III (2008-2015), and Kangoo (2007-2018). It was also fitted to the Nissan Micra K13 (2010-2017) as part of the Renault-Nissan alliance.
Aftermarket ECU tuning is common on the K9K-752 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. Expect 4.5-5.0 L/100km (56-52 mpg UK) on a combined cycle in a Clio or Mégane. Real-world figures are typically 5.0-5.5 L/100km (56-51 mpg UK), making it very economical for daily commuting.
Yes. The K9K 752 is an interference engine. If the timing chain were to fail (which is rare but possible), the pistons would collide with the valves, causing catastrophic engine damage. Regular oil changes help prevent chain wear.
Renault specifies RN0710 (5W-30) oil. This is critical for protecting the high-pressure fuel pump and maintaining the health of the emissions system. Using the correct oil significantly reduces the risk of EGR and DPF problems.
