The Renault M9R 828 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2006 and 2018. Developed jointly with Nissan, it features a common‑rail fuel system, variable geometry turbocharger (VGT), and double overhead camshafts (DOHC). Output ranges from 96 kW (130 PS) to 130 kW (177 PS), with torque between 320–380 Nm, providing strong low‑rpm pulling power for everyday drivability.
Fitted to models such as the Laguna III, Mégane III, Scénic III, and Espace IV—alongside Nissan equivalents like the Qashqai and X-Trail—the M9R 828 was engineered for refined performance and fuel efficiency. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), allowing Euro 4 compliance initially, with later variants meeting Euro 5 and Euro 6 standards.
One documented concern is dual-mass flywheel (DMF) degradation, which can cause driveline shudder or noise under load. This issue is referenced in Renault Service Bulletin RNT/2011/08 and is often accelerated by frequent short trips or aggressive driving. From 2014, Renault introduced a reinforced DMF design and updated clutch kits to address premature wear.
Production years 2006–2009 meet Euro 4 standards; 2010–2014 models meet Euro 5; 2015–2018 variants comply with Euro 6 (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9R 828 is a 1,995 cc inline‑four turbo‑diesel engineered for mid‑size and large passenger vehicles (2006–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and smooth highway cruising. Designed to meet Euro 4 through Euro 6 emissions standards, it balances performance with fuel economy.

The M9R 828 delivers smooth torque ideal for motorway cruising but requires strict adherence to 20,000 km or 12-month oil change intervals to protect the high-pressure fuel pump and turbo. Renault RN0720 (5W-30) oil is essential due to its low-SAPS formulation compatible with DPF systems. Short-trip driving accelerates DMF wear and carbon buildup in the EGR circuit. From 2014, updated flywheel and EGR cooler designs improved reliability. Bosch CP4.2 pumps demand ultra-low-sulfur diesel (EN 590) to prevent internal seizure.
Oil Specs: Requires Renault RN0720 (5W-30) low-SAPS oil (Renault SIB RNT/2011/08). Equivalent to ACEA C4.
Emissions: Euro 4 applies to 2006–2009 models; Euro 5 to 2010–2014; Euro 6 to 2015–2018 (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under UN ECE R85. Higher outputs (130 kW) require EN 590-compliant diesel (Renault TIS Doc. R26015).

The Renault M9R 828 was used across Renault's Laguna III, Mégane III, Scénic III, and Espace IV platforms with transverse mounting and co-developed with Nissan for shared applications. This engine received platform-specific adaptations—reinforced mounts in the Espace and revised intake manifolds in the Mégane R.S. dCi—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 Qashqai, X-Trail, and Primera. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Renault TIS R24890). The 7th VIN digit indicates engine family ('8' for M9R series). Early Euro 4 engines have silver valve covers; Euro 5/6 units use black. Critical differentiation from M9R Gen 2: M9R 828 uses Bosch EDC16C39 or EDC17C49 ECU with round OBD port; later M9R Gen 2 (846) uses Denso ECU. Service parts require production date verification—flywheel and clutch kits for pre-2014 engines are incompatible with post-2014 Euro 6 variants due to DMF redesign (Renault SIB RNT/2011/08).
The M9R 828's primary reliability risk is dual-mass flywheel (DMF) failure, with elevated incidence in stop-start urban use and short-trip driving. Renault internal service data (2013) indicated up to 30% of pre-2014 engines required DMF replacement before 150,000 km, while UK DVSA MOT records show EGR-related emissions faults as a common failure mode in high-mileage examples. Frequent cold starts and infrequent oil changes accelerate wear, making adherence to service intervals critical.
