The Renault M9T 706 is a 2,298 cc, inline‑four turbo‑diesel engine produced between 2011 and 2018. It features a DOHC 16‑valve layout, common‑rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivered 120 kW (163 PS) and 360 Nm of torque, with strong low‑rpm pull suited to commercial and light‑duty applications.
Fitted to models such as the Master III, Trafic II, and Nissan NV300—particularly the dCi 165 variants—the M9T 706 was engineered for durability, load-carrying capability, and fleet-serviceability. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 5 standards across all production years.
One documented concern is premature wear of the dual‑mass flywheel (DMF), leading to driveline vibration and clutch shudder. This issue, highlighted in Renault Technical Note NTM‑10‑2014, is attributed to torsional stress in stop‑start urban delivery cycles. From 2015, revised DMF components with improved heat shielding were introduced across the M9T range to enhance service life.
All production years 2011–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/2012/7654).
The Renault M9T 706 is a 2,298 cc inline‑four turbo‑diesel engineered for light commercial vehicles and vans (2011–2018). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver robust low-end torque and fleet-ready reliability. Designed to meet Euro 5 emissions standards, it balances load-carrying performance with regulatory compliance and service interval practicality.

The M9T 706 provides strong low-end torque ideal for urban delivery and stop-start duty cycles but requires strict adherence to 20,000 km oil change intervals using RN0700/ACEA C3 oil to protect the Bosch CP3.4 fuel system and timing chain. Extended oil intervals increase risk of injector coking and chain wear. The dual-mass flywheel is prone to fatigue in high-torque, low-speed applications; post-2015 models feature reinforced components per Renault NTM‑10‑2014. DPF regeneration must complete uninterrupted—frequent short trips may trigger limp mode or require forced regeneration.
Oil Specs: Requires Renault RN0700 or ACEA C3 (5W-30) specification (Renault SIB NTM‑10‑2014). Not compatible with older ACEA B4 oils.
Emissions: Euro 5 certification applies to all 2011–2018 M9T 706 engines (VCA Type Approval #VCA/EMS/2012/7654). No Euro 6 variants exist for this code.
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (Renault PT‑2015).

ISO 1585: Road vehicles — Engine test code
The Renault M9T 706 was used across Renault's Master III and Trafic II platforms with longitudinal mounting and licensed to Nissan for the NV300. This engine received platform-specific adaptations—reinforced engine mounts in the Master and revised cooling ducts in the Trafic—and from 2015 the DMF upgrade improved driveline compatibility, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side engine block near the cylinder head flange (Renault TIS M9T‑ID‑01). The 7th VIN digit for Renault vehicles is '7' for M9T 706 applications. Pre-2015 units use a dual-mass flywheel with part number 7701490XXX; post-2015 revisions use 7701490YYY with improved heat shielding. Critical differentiation from M9T 720: M9T 706 has lower boost pressure (1.9 bar vs 2.2 bar) and unique injector calibration.
The M9T 706's primary reliability risk is dual-mass flywheel degradation, with elevated incidence in urban stop-start delivery use. Renault internal data from 2015 indicated over 18% of pre-2015 engines required DMF replacement before 100,000 km, while UK DVSA MOT records show DPF-related failures rising after 120,000 km in high-idle commercial fleets. Frequent short trips and incomplete regenerations accelerate both issues, making driving pattern and service discipline critical.
