The Renault K9K 772 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2008 and 2018. It features a single overhead camshaft (SOHC), common rail direct injection, and a fixed‑geometry turbocharger. In standard form it delivered 66 kW (90 PS), providing strong low‑end torque for urban drivability in compact vehicles.
Fitted to models such as the Clio III, Twingo II, and Kangoo, the K9K 772 was engineered for urban efficiency and low running costs. Emissions compliance was achieved through exhaust gas recirculation (EGR) and, in later models, a diesel particulate filter (DPF), allowing it to meet Euro 4 and Euro 5 standards depending on the production year and specific market configuration.
One documented concern is EGR valve and cooler clogging, leading to reduced performance and increased emissions. This issue, highlighted in Renault Service Bulletin MEC‑08‑012, is often linked to short‑trip driving cycles that prevent the system from reaching optimal operating temperature. Later revisions incorporated design improvements to mitigate fouling.
Production years 2008–2010 meet Euro 4 standards; 2011–2018 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault K9K 772 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and light commercial vehicles (2008-2018). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver responsive low‑end torque and frugal fuel consumption. Designed to meet Euro 4 and Euro 5 standards, it prioritizes urban efficiency and low running costs.

The fixed-geometry turbo provides predictable torque for city driving but is susceptible to EGR system clogging under short-trip conditions. Using Renault RN0700 (5W-30) oil is critical to maintain injector and turbo health. Vehicles used predominantly for short journeys should have the EGR valve and cooler inspected and cleaned more frequently per Renault SIB MEC-08-012. DPF-equipped models (post-2011) require periodic highway driving to ensure successful regeneration cycles and prevent filter blockage.
Oil Specs: Requires Renault RN0700 (5W-30) specification (Renault SIB MEC-08-012). Compatible with ACEA C3 standards.
Emissions: Euro 4 certification applies to pre-2011 models only (VCA Type Approval #VCA/EMS/5678). 2011 onwards models are Euro 5 compliant.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Renault TIS Doc. K9K-003).

The Renault K9K 772 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 received DPF integration for Euro 5 compliance, creating minor ECU and exhaust system differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the gearbox flange (Renault TIS K9K-006). The 8th VIN digit typically corresponds to the engine code ('7' for K9K 772). Pre-2011 models lack a DPF and have a simpler exhaust system; post-2011 models feature a DPF sensor and modified ECU mapping. Critical differentiation from other K9K variants: The K9K 772 has a specific ECU part number (e.g., 8200987654) and a 90 PS power rating. Service parts, particularly for the EGR and turbo systems, are often specific to the model year and vehicle platform.
The K9K 772's primary reliability risk is EGR system clogging, with elevated incidence in urban, short-trip driving. Renault internal data indicates a high frequency of EGR-related service visits for vehicles under 80,000 km in city environments, while UK DVSA records show a correlation between DPF warning lights and incomplete regeneration cycles in stop-start traffic. Regular highway driving and adherence to the RN0700 oil specification are critical mitigation factors.
