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 efficien…
Production years 2007–2010 meet Euro 4 standards; 2011–2018 models meet Euro 5 compliance depending on market .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 732 is generally robust with a simple design, but long-term reliability heavily depends on usage. Vehicles used for long journeys are typically trouble-free, while those used for short trips often face EGR and DPF issues. Regular oil changes and using the correct fuel are crucial for longevity.
The most frequent issues are EGR valve/clogging, glow plug failures, and leaks from injector seals or fuel return lines. Turbo actuator problems and DPF regeneration faults are also common, especially in urban-driven cars. These are well-documented in Renault service notes.
This 1.5L dCi engine was used in the Clio III, Twingo II, Modus, and Kangoo. It was also found in the Dacia Sandero and the Nissan Micra K13. Power output is typically 90 PS, making it a popular choice for compact, economical vehicles across these brands.
Aftermarket ECU tuning is common on the K9K-732 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Excellent for its era. In a Clio or Twingo, expect 4.5-5.0 L/100km (56-52 mpg UK) on a combined cycle. Highway driving can yield under 4.0 L/100km (70+ mpg UK). Real-world economy in city driving is lower, around 5.5-6.5 L/100km (51-43 mpg UK), especially if the EGR system is clogged.
Yes. The K9K 732 is an interference engine. If the timing chain were to fail or jump (though rare), the pistons would collide with the open valves, causing catastrophic internal engine damage. This underscores the importance of addressing any unusual engine noises promptly.
Renault mandates RN0700 or RN0710 specification oil, typically a 5W-30 synthetic. This low-SAPS oil is essential for protecting the DPF (on post-2011 models) and ensuring the longevity of the high-pressure fuel pump. Using the wrong oil can lead to DPF blockage and expensive repairs.
