The Renault K9K 800 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2007 and 2018. It features a cast‑iron block, aluminium head, common‑rail direct injection, and a fixed‑geometry turbocharger. In its 64 kW (87 PS) form, it delivers peak torque of 200 Nm, providing adequate low‑end pull for urban driving and light loads.
Fitted to models like the Clio III, Mégane III, and Kangoo, the K9K 800 was engineered for cost‑effective, reliable urban mobility and light commercial use. Emissions compliance was initially met through exhaust gas recirculation (EGR), with later models incorporating a diesel particulate filter (DPF) to achieve Euro 5 standards.
A documented concern involves EGR valve and cooler clogging, particularly in vehicles subjected to frequent short trips, as noted in Renault Technical Note EM‑5512. This leads to reduced performance and increased emissions. From 2011, Renault introduced revised EGR components and software calibrations to mitigate the issue.
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 800 is a 1,461 cc inline‑three turbo‑diesel engineered for superminis and light vans (2007-2018). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver adequate low‑end torque for city driving. Designed to meet Euro 4 and Euro 5 standards, it prioritizes fuel economy and compact packaging.

The fixed-geometry turbo provides predictable, if modest, performance suited to city driving but is sensitive to EGR system health. Using Renault RN0700 (5W-30) oil is critical to maintain injector and turbo longevity. Vehicles used primarily for short trips are prone to EGR and DPF clogging; regular highway runs are recommended to facilitate passive regeneration. The timing chain is generally robust but requires inspection if unusual noise is detected. Software updates for the ECU are available to optimize EGR function per Renault Technical Note EM-5512.
Oil Specs: Requires Renault RN0700 (5W-30) specification (Renault SIB EM-5512). Compatible with ACEA B4.
Emissions: Euro 4 certification applies to 2007–2010 models; Euro 5 applies to 2011–2018 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Renault TIS Doc. K9K-003).

The Renault K9K 800 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 Kangoo-and from 2011 the Euro 5 models incorporated a DPF, creating minor parts differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the fuel filter (Renault TIS K9K-005). The 8th VIN digit often corresponds to the engine variant ('K' for K9K series). Pre-2011 models lack a DPF and have a simpler exhaust manifold; post-2011 Euro 5 models have a bulkier exhaust system with a DPF canister. Critical differentiation from higher-powered K9K variants: The K9K 800 has a single-mass flywheel and a lower-output Bosch EDC16C34 ECU. Service parts, particularly for the emissions system, are not always interchangeable between pre- and post-2011 models (Renault SIB EM-5512).
The K9K 800's primary reliability risk is EGR system clogging, with elevated incidence in vehicles used for short urban journeys. Renault internal data indicated a high service rate for EGR cleaning/replacement in city-based Kangoo vans, while UK DVSA records show a correlation between low annual mileage and emissions-related MOT failures. Infrequent DPF regeneration cycles make preventative maintenance critical.
Analysis derived from Renault technical bulletins (2010-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
