The Renault M9T 704 is a 2,298 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. Developed jointly with Nissan under the Renault–Nissan Alliance, it features a common‑rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). Power output ranges from 120 kW (163 PS) to 147 kW (200 PS), with torque between 360–450 Nm, providing strong low‑rpm pulling power ideal for commercial and passenger applications.

Production years 2010–2014 meet Euro 5 standards; 2015–2018 variants comply with Euro 6 .
The Renault M9T 704 is a 2,298 cc inline‑four turbo‑diesel engineered for light commercial and large passenger vehicles (2010–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver high torque at low rpm and robust performance under load. Designed to meet Euro 5 and Euro 6 emissions standards, it balances workhorse capability with regulatory compliance.

The Renault M9T 704 was used across Renault's Master III, Trafic III, Movano B, and Alaskan platforms with longitudinal mounting and co-developed with Nissan for shared applications. This engine received platform-specific adaptations—reinforced sump in the Master and revised cooling circuits in the Alaskan—and from 2015 the Euro 6 variants adopted a new EGR cooler and updated DPF control logic, creating interchange limits. Partnerships enabled Nissan to use the same block in the NV400, Primastar, and Navara. 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 M9T 704 offers strong torque and durability for commercial use, but early models (2010–2013) are prone to dual-mass flywheel and EGR issues. Later Euro 6 variants (2015+) improved reliability with updated components. Regular oil changes using RN0720 5W-30 and avoiding extended idling greatly extend engine life.
Top issues include dual-mass flywheel wear, EGR cooler clogging, high-pressure fuel pump (Denso HP3) failure, and turbo actuator sticking. These are well-documented in Renault service bulletins RNT/2012/05 and RNT/2013/02, especially in high-mileage or poorly maintained vehicles.
The M9T 704 powered the Master III, Trafic III, Movano B, and Alaskan from 2010–2018. It was also used by Nissan in the NV400, Primastar, and Navara under joint development. Power outputs range from 163 to 200 PS across both brands.
Aftermarket ECU tuning is common on the M9T-704 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.
In a Master III dCi 145, expect ~8.5 L/100km (urban) and ~6.2 L/100km (highway), or ~34 mpg UK combined. Real-world mixed driving typically returns 30–38 mpg (UK), depending on load, driving style, and maintenance condition.
Yes. The M9T series is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is generally durable with proper oil maintenance.
Renault specifies 5W-30 synthetic oil meeting RN0720 (low-SAPS) standard. This protects the DPF and turbo. Change every 20,000 km or 12 months—whichever comes first—to prevent sludge and fuel pump wear.
