The Renault K9K 802 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 most common form, it delivers 66 kW (90 PS) and 200 Nm of torque, with a double overhead camshaft (DOHC) design enabling precise valve control for responsive low‑end power.
Fitted to popular models like the Clio III, Mégane III, and Kangoo, the K9K 802 was engineered for urban efficiency and low running costs. Its compact three‑cylinder layout contributes to light weight and fuel economy, making it ideal for city driving. Emissions compliance was managed through exhaust gas recirculation (EGR), meeting Euro 4 and Euro 5 standards depending on the model year and specific market configuration.
A well‑documented service concern involves the high‑pressure fuel pump, which can fail prematurely if low‑quality fuel or incorrect oil is used, as noted in Renault Technical Note MEC‑08‑012. This is often linked to internal wear from fuel contamination or lubrication issues. Renault addressed this in later production runs with revised pump components and updated maintenance schedules.
Production years 2007–2010 meet Euro 4 standards; 2011–2018 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 802 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 excellent fuel efficiency. Designed to meet Euro 4 and Euro 5 standards, it prioritizes urban drivability and low running costs.

The fixed-geometry turbo provides predictable, linear power delivery suited to city driving but demands strict adherence to 15,000 km oil change intervals using RN0700/RN0710 specification oil to protect the high-pressure fuel pump and timing chain. Ultra-low-sulfur diesel (ULSD) meeting EN 590 standards is mandatory to prevent injector and pump wear. The chain-driven valvetrain is generally robust but requires periodic inspection for tensioner wear. EGR valve clogging is common in stop-start traffic, necessitating cleaning every 60,000 km to maintain performance and emissions compliance. Pre-2011 models should use Euro 4-compliant fluids.
Oil Specs: Requires Renault RN0700 or RN0710 (5W-30) specification (Renault Tech Note MEC-08-012). ACEA B4 is the minimum acceptable standard.
Emissions: Euro 4 certification applies to 2007-2010 models (VCA Type Approval #VCA/EMS/5678). Euro 5 compliance is standard for 2011-2018 models.
Power Ratings: Measured under ISO 1585 standards. Output is consistent across model range (Renault Group PT-2018).

The Renault K9K 802 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 updated Mégane III Phase 2 models featured revised ECU mapping for Euro 5 compliance, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault Tech Manual 1307A). The 8th VIN digit typically corresponds to the engine code (e.g., '8' for K9K 802). Visually, it is a compact 3-cylinder engine with a black plastic cam cover and a Garrett turbocharger mounted at the front. Critical differentiation from the K9K 798: The 802 variant has a Siemens VDO fuel pump and specific ECU part numbers (e.g., 8200899087). Service parts, particularly fuel system components, are not interchangeable with earlier K9K variants without ECU reprogramming (Renault SIB MEC-10-005).
The K9K 802's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using non-compliant fuel or oil. Renault internal service data indicates a notable failure rate before 150,000 km under these conditions, while UK DVSA records show EGR-related faults are the second most common cause of emissions test failures. Extended oil change intervals and low-quality fuel make adherence to RN0700/RN0710 oil specification critical.
Analysis derived from Renault technical bulletins (2008-2016) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
