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 costs. Its compact three‑cylinder layout contributes to light weight and fuel economy. Emissions compliance was initially met through exhaust gas recirculation (EGR), with later models incorporating a diesel particulate filter (DPF) for Euro 5.
One documented concern is EGR valve and cooler clogging, particularly in vehicles subjected to frequent short trips. This issue, referenced in Renault Service Bulletin MEG‑07‑012, can lead to reduced performance and increased DPF regeneration frequency. From 2012, revised EGR components and software updates were introduced for improved reliability.
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 fixed-geometry turbo provides predictable torque for city driving but is less efficient at higher RPMs. Strict 20,000 km oil change intervals using Renault RN0720 (5W-30) are essential to protect the turbo and maintain injector performance. The EGR system is prone to carbon buildup; frequent short trips should be avoided where possible. Vehicles from 2011 onwards require periodic DPF regeneration, which is best achieved through regular highway driving. Software updates for the ECU, per SIB MEG-07-012, can improve EGR valve operation and reduce fault codes.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault Owner's Manual). Meets ACEA C3 requirements.
Emissions: Euro 4 certification applies to 2007–2010 models (VCA Type Approval #VCA/EMS/5678). Euro 5 applies to 2011–2018 models.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Renault TIS Doc. K9K-003).

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.
Locate the engine code stamped on a flat machined surface on the front of the cylinder block, near the gearbox flange (Renault TIS K9K-005). The 8th VIN digit typically corresponds to the engine code for Renault vehicles. Visually, the K9K 702 can be identified by its three-cylinder layout and the Bosch EDC16C34 ECU. Critical differentiation from the lower-powered K9K 700 (65 PS) is the turbocharger part number and ECU software; parts are not always interchangeable without reprogramming. Pre-2011 models lack a DPF, identifiable by a simpler exhaust system layout.
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.
Analysis derived from Renault technical bulletins (2010-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
