The Renault K9K 772 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2008 and 2018. It features a single overhead camshaft (SOHC), common rail direct injection, and a fixed‑geometry turbocharger. In standard form it delivered 66 kW (90 PS), providing strong low‑end torque for urban drivability in compact vehicles.
Fitted to models such as the Clio III, Twingo II, and Kangoo, the K9K 772 was engineered for urban efficiency and low running costs. Emissions…
Production years 2008–2010 meet Euro 4 standards; 2011–2018 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 772 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and light commercial vehicles (2008-2018). 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 prioritizes urban efficiency and low running costs.

The Renault K9K 772 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 2011 received DPF integration for Euro 5 compliance, creating minor ECU and exhaust system differences. All adaptations are documented in OEM technical bulletins.
The K9K 772's primary reliability risk is EGR system clogging, with elevated incidence in urban, short-trip driving. Renault internal data indicates a high frequency of EGR-related service visits for vehicles under 80,000 km in city environments, while UK DVSA records show a correlation between DPF warning lights and incomplete regeneration cycles in stop-start traffic. Regular highway driving and adherence to the RN0700 oil specification are critical mitigation factors.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 772 is generally robust with simple mechanics, but its longevity heavily depends on usage. Engines in vehicles used for long journeys are very reliable. Those in city cars face EGR and DPF issues. Using the correct RN0700 oil and addressing EGR warnings promptly is key to long-term health.
The most frequent issues are EGR valve/cooler clogging, DPF regeneration failures (on post-2011 models), turbo actuator problems, and glow plug/relay failures. These are well-documented in Renault service bulletins, particularly for vehicles with high urban mileage.
The K9K 772 1.5 dCi 90 engine was used in the Renault Clio III (2008-2012), Twingo II (2011-2014), and Kangoo (2008-2018). It was also fitted to the Dacia Sandero (2012-2016). Power output is consistently 90 PS across all applications.
Yes, modest power gains (up to 110-115 PS) are possible via ECU remapping. The engine and turbo can handle this increase. However, aggressive tuning is not recommended as it can overstress the fixed-geometry turbo and increase the risk of EGR/DPF problems. Supporting modifications are rarely needed for stage 1.
Excellent for its era. In a Renault Clio III, expect around 4.5 L/100km (63 mpg UK) on a combined cycle. Real-world figures vary: 5.5-6.0 L/100km (47-51 mpg UK) in city driving and 4.0-4.5 L/100km (63-70 mpg UK) on highways. DPF models may see slightly higher consumption if regeneration is frequent.
Yes. The K9K 772 is an interference engine. If the timing chain were to fail (a rare occurrence on this engine), 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 RN0700 specification oil, typically SAE 5W-30. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is critical for protecting the EGR system and, on later models, the DPF from clogging. Using the wrong oil will accelerate component failure.
