The Renault M9R 824 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2008 and 2018. Developed jointly with Nissan and used across Renault’s premium and commercial vehicle lines, it features a common‑rail fuel system, variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 96 kW (130 PS), with higher-output variants reaching 110 kW (150 PS) and torque figures of 320–360 Nm.
Fitted to models such as the Laguna III, Mégane III, Scénic III, and Espace IV, including the popular dCi 130 and dCi 150 trims, the M9R 824 was engineered for smooth torque delivery, refined cruising, and strong fuel economy. 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), often manifesting as drivetrain shudder or clunking under load. This issue, highlighted in Renault Technical Note NTM 08‑112, is attributed to heat and torsional stress in stop‑start urban use. From 2014, revised DMF designs were introduced alongside updated clutch kits to improve durability.
Production years 2008–2014 meet Euro 5 standards; 2015–2018 models may have Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9R 824 is a 1,995 cc inline‑four turbo‑diesel engineered for mid‑size passenger and MPV platforms (2008–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver smooth low‑end torque and efficient highway cruising. Designed to meet Euro 5 (and select Euro 6) standards, it balances performance with economy.

The M9R 824 delivers smooth, linear torque ideal for both city and motorway driving but requires strict adherence to 20,000 km oil change intervals to protect the high-pressure CP4.2 fuel pump and timing chain. 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 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. 110 kW output requires EN 590-compliant diesel (Renault TIS Doc. M9R‑010).

ISO 1585: Road vehicles — Engine test code
The Renault M9R 824 was used across Renault's Laguna III, Mégane III, and Espace IV platforms with transverse mounting and shared with Nissan for longitudinal applications in European and global markets. This engine received platform-specific adaptations—reinforced engine mounts in the Espace and revised intake manifolds in the Scénic—and from 2015 the facelifted Mégane IV adopted the M9R Gen 3 with updated emissions hardware, creating interchange limits. Partnerships enabled Nissan's dCi 130/150 variants in Qashqai and X-Trail. 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 M9R‑003). The 7th VIN digit indicates engine family ('8' for M9R 824). 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 M9R 800: M9R 824 has higher-pressure CP4.2 pump and larger intercooler. 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 M9R 824's primary reliability risk is dual-mass flywheel (DMF) degradation, with elevated incidence in urban stop-start use. Renault internal quality reports from 2013 noted a significant share of dCi 130/150 vehicles 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 driving accelerate wear, making timely replacement with updated OEM parts critical.
