The Renault K9K 760 is a 1,461 cc, inline‑four turbo‑diesel engine produced between 2008 and 2015. It features a robust cast‑iron block, double overhead camshafts (DOHC), and a fixed‑geometry turbocharger, delivering outputs between 66 kW (90 PS) and 81 kW (110 PS) with torque figures of 200–240 Nm. Its simple, durable architecture prioritizes cost‑effective ownership and strong low‑end pull for urban drivability.
Fitted to popular models like the Clio III, Mégane II…
Production years 2008–2011 meet Euro 4 standards; 2012–2015 models typically meet Euro 5 compliance (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 760 is a 1,461 cc inline‑four turbo‑diesel engineered for supermini and compact MPV applications (2008-2015). It combines a fixed‑geometry turbocharger with a common‑rail fuel system to deliver strong low‑end torque and frugal fuel consumption. Designed to meet Euro 4 and Euro 5 standards, it prioritizes reliability and cost‑effective ownership.

The Renault K9K 760 was used across Renault's B/C platform vehicles with transverse mounting. This engine received platform-specific adaptations-different intake manifolds for the Clio versus the Kangoo-and from 2012 minor ECU and EGR revisions were implemented for Euro 5 compliance, though core mechanical parts remain largely interchangeable. All adaptations are documented in OEM technical bulletins.
The K9K 760's primary reliability risk is EGR system clogging, with elevated incidence in vehicles used for short urban journeys. Renault internal service data indicates a high frequency of EGR-related repairs before 100,000 km for city-driven vehicles, while UK DVSA MOT statistics show EGR faults as a leading cause of diesel particulate filter (DPF) warning lights. Inadequate warm-up cycles make preventative cleaning or using higher-quality fuel critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 760 is renowned for its mechanical robustness and longevity when properly maintained. Its main weakness is the EGR system, which clogs easily with short trips. Addressing EGR issues promptly and using the correct 5W-30 oil allows many examples to exceed 200,000 km without major problems.
The most frequent issues are EGR valve/cooler clogging, high-pressure fuel pump failure, turbo actuator sticking, and glow plug/module faults. These are well-documented in Renault service bulletins, with EGR problems being the most prevalent in urban use.
The K9K 760 was widely used in Renault's lineup from 2008-2015, powering the Clio III, Mégane III, Scénic III, and Kangoo. It was also fitted to the Dacia Duster (2010-2015) and Nissan Micra/Micra C+C (K13) in certain markets.
Yes, the K9K 760 responds well to ECU remapping. A Stage 1 remap can safely increase power to 95-100 kW (130-135 PS) and torque to 260-280 Nm. The bottom end is strong, but supporting modifications like a better intercooler are recommended for sustained high performance.
Excellent for its era. In a Clio III dCi 90, expect 4.5 L/100km (63 mpg UK) on a combined cycle. Real-world figures range from 50-65 mpg UK (4.2-5.6 L/100km) depending on model, driving style, and whether the EGR system is functioning correctly.
Yes. The K9K 760 is an interference engine. If the timing chain were to fail (though rare), the pistons would collide with the open valves, causing catastrophic internal damage. Fortunately, the chain is very durable with proper oil changes.
Renault mandates a 5W-30 synthetic oil meeting RN0700 or RN0710 specifications. Using the correct low-ash oil is vital for protecting the fuel pump, turbo, and preventing excessive soot buildup that clogs the EGR and DPF systems.
