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 eng…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 802 is generally robust with a simple chain-driven design, but its longevity heavily depends on using the correct RN0700/RN0710 oil and high-quality diesel fuel. The main weakness is the high-pressure fuel pump, which can fail prematurely if maintenance is neglected. With strict adherence to service schedules, these engines can reliably exceed 200,000 km.
The most frequent issues are high-pressure fuel pump failure, EGR valve/carbon buildup causing running problems, turbo actuator faults leading to boost issues, and glow plug/relay failures affecting cold starts. These are well-documented in Renault service bulletins and owner reports.
The K9K 802 was widely used in Renault's lineup from 2007-2018, powering the Clio III, Mégane III, and Kangoo II. It was also fitted to Dacia models like the Sandero I and Logan I during the same period, typically in the 86 or 90 PS variants.
Yes, the K9K 802 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 quite strong for moderate gains. However, pushing beyond this requires upgrades like a hybrid turbo and intercooler to ensure reliability.
Excellent for its era. In a Renault Clio III 1.5 dCi, expect real-world figures of around 5.0 L/100km (56 mpg UK) on a mixed run. Highway driving can see figures as low as 4.0 L/100km (70 mpg UK), while city driving might be closer to 6.0 L/100km (47 mpg UK).
Yes. The K9K 802 is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper oil changes.
Renault mandates oil meeting the RN0700 or RN0710 specification, typically a 5W-30 synthetic. Using ACEA B4-compliant oil is the absolute minimum. Never use generic or incorrect oil, as it is the primary cause of premature high-pressure fuel pump failure.
