The Renault K9K 732 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, offering a blend of compact size and strong low‑end pull for city and urban driving.
Fitted extensively to the Clio III, Twingo II, Modus, and Kangoo, the K9K 732 was engineered for fuel efficiency and low running costs in compact vehicles. Emissions compliance was met through exhaust gas recirculation (EGR) and, in later models, a diesel particulate filter (DPF), achieving Euro 4 and Euro 5 standards depending on the model year and market.
One documented concern is EGR valve and cooler clogging, leading to reduced performance and increased emissions. This issue, referenced in Renault Technical Note MEC 07‑01‑2012, is often linked to short‑trip driving cycles that prevent the system from reaching optimal cleaning temperatures. Later production runs incorporated revised EGR components for improved reliability.
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 732 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and light commercial vehicles (2007-2018). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver strong low‑rpm torque and frugal fuel consumption. Designed to meet Euro 4 and Euro 5 standards, it balances urban agility with operational economy.

The fixed-geometry turbo provides predictable, lag-free torque ideal for stop-start traffic but is susceptible to carbon buildup in the EGR system under short-trip conditions. Renault RN0700/RN0710 (5W-30) oil is mandatory to protect the high-pressure fuel pump and maintain chain lubrication. Vehicles used predominantly for short journeys require more frequent EGR and intake manifold cleaning to prevent performance loss and DPF regeneration issues. The timing chain is generally robust but should be inspected if unusual noise is detected. Bosch CP1 pump longevity is directly linked to fuel quality; only ultra-low-sulfur diesel (EN 590) should be used.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Service Manual 60R). These are low-SAPS oils designed for DPF compatibility.
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 SAE J1349 standards. Output is consistent across model range (Renault Group PT-2015).

The Renault K9K 732 was used across Renault's B/C-segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Kangoo and specific ECU calibrations for the Twingo-and from 2011 received updates for Euro 5 compliance, including a DPF on some variants. 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 Service Manual 60R). The 8th VIN digit often corresponds to the engine code (e.g., '7' for K9K 732). Pre-2011 models lack a DPF and have a simpler EGR cooler; post-2011 Euro 5 models feature a DPF canister under the vehicle. Critical differentiation from K9K 800: The K9K 732 has a 90 PS output and a specific Bosch EDC16C3 ECU. Service parts, particularly for the fuel system and EGR, require verification against the engine's production date and emissions standard.
The K9K 732's primary reliability risk is EGR system clogging, with elevated incidence in vehicles used for short urban trips. Renault internal data indicated a high rate of EGR-related faults in city-driven vehicles, while UK DVSA MOT statistics frequently cite emissions failures linked to this issue. Short journeys prevent the system from self-cleaning, making proactive maintenance critical.
Analysis derived from Renault technical bulletins (2007-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
