The Renault K9K 702 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2007 and 2018. It features a cast iron block, aluminium cylinder head, common rail direct injection, and a fixed‑geometry turbocharger. In standard European specification, it produced 66 kW (90 PS) and 200 Nm of torque, offering strong low‑rpm pull for its size.
Fitted to models such as the Clio III, Mégane III, and Kangoo, the K9K 702 was engineered for urban efficiency and low running cos…
Production years 2007–2010 meet Euro 4 standards; 2011–2018 models meet Euro 5 compliance (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 702 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and compact MPV applications (2007-2018). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver responsive low‑end torque and frugal consumption. Designed to meet Euro 4 and Euro 5 standards, it prioritises urban efficiency and low ownership costs.

The Renault K9K 702 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 the introduction of the DPF for Euro 5 compliance, creating minor software and hardware differences. All adaptations are documented in OEM technical bulletins.
The K9K 702'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, while UK DVSA records show DPF warning lights are a common MOT advisory item for high-mileage examples. Infrequent highway driving increases soot accumulation, making periodic long runs and correct oil specification critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 702 is generally robust with a simple design, but its longevity heavily depends on maintenance and usage. The main concerns are the EGR system and, on later models, the DPF. Regular oil changes, using the correct specification, and avoiding constant short trips are key to achieving high mileage without major issues.
The most frequent issues are EGR valve/cooler clogging, DPF problems on Euro 5 models, turbo actuator failure, and high-pressure fuel pump wear. These are well-documented in Renault service bulletins and often linked to driving conditions and maintenance intervals.
The 1.5 dCi 90 PS engine was widely used in the Clio III (2007-2012), Mégane III (2008-2015), and Kangoo II (2007-2018). It was also found in the Nissan Micra K13 (2010-2016) as part of the Renault-Nissan alliance. All are transverse, front-wheel-drive applications.
Yes, the K9K 702 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 110-115 PS and torque to 240-250 Nm. The standard internals are strong, but supporting modifications like a better intercooler are recommended for sustained performance. Always use a reputable tuner.
Excellent for its era. In a Renault Clio III, expect real-world figures of 4.5-5.0 L/100km (56-63 mpg UK) on a mixed run. Highway driving can yield under 4.0 L/100km (70+ mpg UK). City driving will be higher, around 5.5-6.5 L/100km (43-51 mpg UK), especially if DPF regenerations are frequent.
Yes. The K9K 702 is an interference engine. If the timing chain fails or jumps, the pistons will collide with the valves, causing catastrophic internal damage. While the chain is designed to last the engine's life, any unusual noises from the timing cover should be investigated immediately.
Renault mandates oil meeting the RN0720 specification, typically a 5W-30 synthetic low-SAPS (Low Ash) oil. This is critical for protecting the DPF (on applicable models) and the turbocharger. Using the wrong oil can lead to premature DPF blockage and increased engine wear.
