The Renault K9K 768 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2007 and 2018. It features a cast iron block, aluminium head, and a single overhead camshaft (SOHC) with 12 valves. Common — rail direct injection and a fixed — geometry turbocharger deliver outputs ranging from 63 kW (85 PS) to 72 kW (98 PS), providing strong low — rpm torque for everyday drivability in compact vehicles.
Fitted to models such as the Clio III, Modus, and Twingo II, the K9K 768 wa…
Production years 2007–2010 meet Euro 4 standards; 2011–2018 models meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 768 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and compact city cars (2007-2018). 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 ownership costs.

The Renault K9K 768 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 Twingo-and from 2011 the introduction of a diesel particulate filter (DPF) for Euro 5 compliance, creating minor service part differences. All adaptations are documented in OEM technical bulletins.
The K9K 768'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 faults in cars with low annual mileage, while UK DVSA records show DPF warning lights as a common MOT advisory item for post-2011 models. Short trip cycles prevent the system from reaching optimal operating temperature, making periodic highway driving and correct oil specification critical.
Analysis derived from Renault technical bulletins (2007-2018) and UK DVSA failure statistics (2015-2023). 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 768 is generally robust with a simple design, but long-term reliability hinges on preventing EGR and DPF issues. Regular oil changes with the correct specification and avoiding constant short trips are crucial. Well-maintained examples can easily exceed 200,000 km without major problems.
The most frequent issues are EGR valve/cooler clogging, DPF regeneration failures (on Euro 5 models), turbo actuator faults, and injector seal leaks. These are well-documented in Renault service bulletins and are often linked to driving patterns and maintenance.
The K9K 768 was primarily used in the Renault Clio III (2007-2012), Renault Modus (2007-2012), and Renault Twingo II (2007-2014). It was also found in the Nissan Micra K13 (2010-2017) as the 1.5 dCi, under the Renault-Nissan alliance partnership.
Yes, the K9K 768 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 110-120 PS and torque to 220-240 Nm. The stock internals are generally strong enough for this level of tune, but supporting modifications like a better intercooler are recommended for longevity.
Excellent for its era. In a Renault Clio dCi 85, expect combined figures of around 4.5 L/100km (63 mpg UK). Real-world economy is typically 5.0-5.5 L/100km (51-56 mpg UK) in mixed driving, making it one of the most economical diesels of its time.
Yes. The K9K 768 is an interference engine. If the timing chain fails or jumps, the pistons will collide with the valves, causing catastrophic internal damage. Fortunately, the chain is very durable and rarely fails if basic maintenance is followed.
Renault specifies RN0700 or RN0710 specification oil, typically SAE 5W-30. For DPF-equipped models (2011+), a low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is mandatory to prevent DPF clogging. Always use a high-quality synthetic oil.
