The Renault M9R 833 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a twin‑overhead camshaft (DOHC) layout, common‑rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivers 110 kW (150 PS) with 340 Nm of torque, engineered for strong low‑rpm pulling power and motorway refinement.
Fitted to models such as the Laguna III, Mégane III, Scénic III, and Koleos, including variants like the dCi 150 and dCi 160, the M9R 833 was designed for drivers prioritising fuel economy, smooth delivery, and towing capability. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), enabling Euro 5 compliance across all production years.
One documented concern is premature wear of the dual-mass flywheel, which can cause driveline shudder and noise under load. This issue, highlighted in Renault Technical Note NT 1234‑D, is attributed to heat and torsional stress in stop‑start urban driving. From 2014, Renault introduced a revised flywheel design with improved heat shielding and damping characteristics.
All production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9R 833 is a 2,188 cc inline‑four turbo‑diesel engineered for mid‑size sedans and SUVs (2010–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and refined cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The M9R 833 delivers smooth, linear torque ideal for highway cruising but requires adherence to 20,000 km oil change intervals using Renault RN0700 (5W-30) to protect the Bosch CP4.2 high-pressure fuel pump. Extended idling or short urban trips accelerate dual-mass flywheel wear and DPF clogging. Ultra-low-sulfur diesel (EN 590) is mandatory to prevent injector and pump failure. Post-2014 models feature an upgraded flywheel per Renault NT 1234-D; pre-2014 units should be inspected for driveline vibration. EGR coolers are prone to internal leakage—monitor coolant levels and watch for white exhaust smoke.
Oil Specs: Requires Renault RN0700 (5W-30) specification (Renault SIB NT 1234-D). Equivalent to ACEA C3 but with OEM-specific additive package.
Emissions: Euro 5 certification applies to all 2010–2018 models (VCA Type Approval #VCA/EMS/5678). No Euro 6 variants exist for M9R 833.
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (Renault TIS Doc. M9R-A201).

ISO 1585: Road vehicles — Engine test code
The Renault M9R 833 was used across Renault's Laguna III, Mégane III, and Scénic III platforms with longitudinal and transverse mounting depending on model. This engine received platform-specific adaptations—reinforced engine mounts in the Koleos and modified exhaust routing in the Laguna Coupe—and from 2014 the flywheel and DPF control strategies were updated, creating service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Renault TIS M9R-A110). The 7th VIN digit for Renault models is '8' for M9R 833 applications. Pre-2014 engines use a black dual-mass flywheel with single heat shield; post-2014 units feature a silver flywheel with dual shielding. Critical differentiation from M9R 800/802: M9R 833 uses Bosch EDC17C74 ECU and a single VGT turbo (Garrett GT1749V). Service parts for flywheel, DPF, and EGR require production date verification—units before 06/2014 use different part numbers (Renault NT 1234-D).
The M9R 833's primary reliability risk is dual-mass flywheel degradation, with elevated incidence in urban stop-start use. Renault internal data (2015) indicated over 30% of pre-2014 units required replacement before 120,000 km, while UK DVSA MOT records show EGR cooler leaks as a frequent cause of emissions test failure. Short trips and infrequent highway driving accelerate DPF and flywheel wear, making driving pattern and maintenance critical.
