The Renault K9K 710 is a 1,461 cc, inline‑four turbo‑diesel engine produced between 2005 and 2010. It features a single overhead camshaft (SOHC) layout with 8 valves and common — rail direct injection. In standard form, it delivered 63 kW (86 PS) and 200 Nm of torque, providing strong low — end pulling power for urban and highway use.
Fitted to models such as the Clio III, Mégane II, and Kangoo, the K9K 710 was engineered for fuel — efficient, low — maintenance motoring with respo…
All production years (2005–2010) meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/6780).
The Renault K9K 710 is a 1,461 cc inline‑four turbo‑diesel engineered for compact hatchbacks and vans (2005-2010). It combines common-rail direct injection with a SOHC 8‑valve head to deliver strong low-end torque and efficient cruising. Designed to meet Euro 4 standards, it balances everyday performance with economy.

The Renault K9K 710 was used across Renault's B/C‑segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Kangoo and revised exhaust manifolds for the Mégane II-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
The K9K 710's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel or extended service intervals. Renault internal service data indicated a notable number of pump replacements under warranty, while owner reports frequently cite EGR valve clogging as a secondary concern. Adherence to correct oil specification and service intervals is critical for long-term engine health.
Analysis derived from Renault technical bulletins (2005-2010) and owner-reported failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 710 is generally robust with a simple, belt-driven design. Its main weakness is the high-pressure fuel pump, which can fail prematurely if poor-quality fuel is used or service intervals are extended. With strict adherence to oil changes using RN0700 5W-40 and timely replacement of the fuel filter and EGR valve, it can easily surpass 250,000 km. It is renowned for its torquey performance and fuel efficiency.
The most frequent issues are high-pressure fuel pump failure, EGR valve clogging, and glow plug failure. A less common but notable issue is the turbocharger actuator failing, leading to loss of boost. The timing belt is critical and must be replaced at 120,000 km to prevent engine damage.
The K9K 710 1.5 dCi diesel engine was used in the Renault Clio III (2005-2010), Mégane II (2005-2008), Scénic II (2005-2009), and Kangoo (2005-2010). It was also found in some Nissan and Dacia models like the Micra and Logan during overlapping production periods.
Yes, modestly. A simple ECU remap can yield an extra 15-20 kW and 50 Nm of torque. More significant power increases require a hybrid turbo and upgraded injectors. The bottom end is strong, but the standard clutch and flywheel are limiting factors and will need upgrading for serious tuning.
Real-world fuel economy is excellent. Expect around 5.0 L/100km (56 mpg UK) in mixed driving for a Clio III. In a heavier Mégane II, figures are around 5.5 L/100km (51 mpg UK). Highway cruising can return 4.2 L/100km (67 mpg UK).
Yes. The K9K 710 is an interference engine. If the timing belt were to fail, the pistons would collide with the valves, causing severe internal engine damage. This is why the 120,000 km replacement interval is non-negotiable.
Renault specifies a 5W-40 synthetic oil meeting the RN0700 standard. Using this specific oil is crucial for protecting the turbocharger and fuel injectors. Change intervals should not exceed 20,000 km or 12 months.
