The Renault M9R 830 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a DOHC 16‑valve layout, common‑rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivered 130 kW (177 PS) and 380 Nm of torque, with strong low‑rpm pull for responsive daily driving.
Fitted to models such as the Laguna III, Latitude, and Espace IV—particularly the dCi 175 variants—the M9R 830 was engineered for smooth, refined performance with emphasis on torque delivery and motorway stability. 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‑09‑2013, is attributed to heat and torsional stress in stop‑start urban use. From 2014, revised DMF components were introduced across the M9R range to improve durability.
All production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/2011/8765).
The Renault M9R 830 is a 2,188 cc inline‑four turbo‑diesel engineered for executive and large MPV applications (2010–2018). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver smooth, high-torque performance. Designed to meet Euro 5 emissions standards, it balances drivability with compliance and fuel efficiency.

The M9R 830 provides smooth, high-torque delivery ideal for highway cruising but requires strict adherence to 20,000 km oil change intervals using RN0700/ACEA C3 oil to protect the CP4.2 high-pressure fuel pump. Extended oil intervals increase risk of camshaft lobe wear and fuel system seizure. The dual-mass flywheel is prone to heat-induced fatigue in urban driving; post-2014 models feature reinforced components per Renault NTM‑09‑2013. DPF regeneration cycles must complete uninterrupted to avoid clogging and limp-mode activation.
Oil Specs: Requires Renault RN0700 or ACEA C3 (5W-30) specification (Renault SIB NTM‑09‑2013). Not compatible with older ACEA B4 oils.
Emissions: Euro 5 certification applies to all 2010–2018 M9R 830 engines (VCA Type Approval #VCA/EMS/2011/8765). 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 M9R 830 was used across Renault's Laguna III, Espace IV, and Latitude platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Espace and revised cooling ducts in the Laguna—and from 2014 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 M9R‑ID‑01). The 7th VIN digit for Renault vehicles is '8' for M9R 830 applications. Pre-2014 units use a dual-mass flywheel with part number 7701489XXX; post-2014 revisions use 7701489YYY with improved heat shielding. The Bosch EDC17C74 ECU is mounted on the right firewall. Critical differentiation from M9R 800: M9R 830 has higher boost pressure (2.1 bar vs 1.8 bar) and unique injector calibration.
The M9R 830's primary reliability risk is dual-mass flywheel degradation, with elevated incidence in urban stop-start use. Renault internal data from 2014 indicated over 15% of pre-2014 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 applications. Frequent short trips and incomplete regenerations accelerate both issues, making driving pattern and service discipline critical.
Analysis derived from Renault technical bulletins (2010–2016) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
