The Renault M9T 702 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). In standard form it delivered 107 kW (145 PS), with torque peaking at 360 Nm for strong low‑end pulling power.
Fitted to models such as the Master III, Trafic III, and Movano B—including the dCi 145 variants—the M9T 702 was engineered for light commercial and van applications requiring durability and load-carrying capability. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), enabling Euro 5 compliance across most production years.
One documented concern is premature wear of the dual-mass flywheel (DMF), particularly in vehicles subjected to frequent stop‑start or heavy-load conditions. This issue, highlighted in Renault Technical Note NTM 08‑112, stems from torsional fatigue under high torque loads. From mid‑2014, revised DMF and clutch kits were introduced to enhance durability across the M9T family.
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models may have Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9T 702 is a 2,298 cc inline‑four turbo‑diesel engineered for light commercial vehicles and MPVs (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 select Euro 6) standards, it balances workhorse capability with fuel efficiency.

The M9T 702 delivers strong low-rpm torque ideal for commercial use and towing but requires strict adherence to 20,000 km oil change intervals to protect the timing chain and turbocharger. Renault RN0720 (5W-30) oil is essential due to its low-SAPS formulation, which safeguards the DPF and EGR system. Extended idling or frequent short trips accelerate carbon buildup in the intake and EGR cooler. Dual-mass flywheel failures are common in high-mileage or stop-start usage; post-2014 models benefit from reinforced DMF units per Renault NTM 08‑112. Use only ultra-low-sulfur diesel (EN 590) to prevent injector and pump wear.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault SIB NTM 08‑112). Equivalent to ACEA C3 but with OEM-specific additive limits.
Emissions: Euro 5 certification applies to pre-2015 models only (VCA Type Approval #VCA/EMS/5678). Some 2015–2018 models meet Euro 6 depending on market.
Power Ratings: Measured under ISO 1585 standards. 107 kW output requires EN 590-compliant diesel (Renault TIS Doc. M9T‑010).

ISO 1585: Road vehicles — Engine test code
The Renault M9T 702 was used across Renault's Master III, Trafic III, and Movano B platforms with longitudinal mounting and shared with Nissan for light commercial applications. This engine received platform-specific adaptations—reinforced sump baffling in the Master and enhanced cooling in the Trafic—and from 2015 the facelifted Movano adopted the M9T Gen 2 with updated emissions hardware, creating interchange limits. Partnerships enabled Nissan's dCi 145 variants in NV300 and Interstar. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side engine block near the cylinder head (Renault TIS M9T‑003). The 7th VIN digit indicates engine family ('9' for M9T series). Pre-2015 models feature silver cam covers and Bosch EDC17C74 ECU; post-2015 Euro 6 variants use black cam covers and Continental EMS3125 ECU. Critical differentiation from M9T 722: M9T 702 is exclusively the 145 PS variant with lower boost pressure and CP3 fuel system. Service parts require production date verification—clutch kits for engines before 06/2014 are incompatible with later units due to flywheel redesign (Renault NTM 08‑112).
The M9T 702's primary reliability risk is dual-mass flywheel (DMF) degradation, with elevated incidence in stop-start or heavy-load commercial use. Renault internal quality reports from 2013 noted a significant share of dCi 145 vans requiring DMF replacement before 150,000 km, while UK DVSA MOT data links drivetrain vibration complaints to this component in high-mileage examples. Frequent short trips and aggressive loading accelerate wear, making timely replacement with updated OEM parts critical.
