The Renault M9R 832 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2006 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 96 kW (130 PS), with higher-output variants reaching 130 kW (177 PS) and torque figures between 320–380 Nm.
Fitted to models such as the Laguna III, Mégane III, Scénic III, and Koleos, the M9R 832 was engineered for a balance of fuel economy, low-end torque, and long-distance refinement. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), allowing pre-2011 units to meet Euro 4 standards, with later builds achieving Euro 5 and Euro 6 depending on market.
One documented concern is premature wear of the dual-mass flywheel and clutch assembly, highlighted in Renault Service Bulletin RSB‑12‑045. This issue is often linked to thermal cycling and torque spikes during gear changes. From 2012, Renault introduced revised flywheel materials and updated clutch kits to mitigate failure rates.
Production years 2006–2010 meet Euro 4 standards; 2011–2014 models meet Euro 5; 2015–2018 variants meet Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9R 832 is a 1,995 cc inline‑four turbo‑diesel engineered for mid‑size and SUV platforms (2006–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 4 through Euro 6 standards (depending on model year), it balances everyday performance with economy.

The M9R 832 delivers smooth torque delivery ideal for motorway cruising but requires strict adherence to 15,000 km oil change intervals using Renault RN0720 (5W‑30 ACEA C3) to protect the high-pressure fuel system and turbo bearings. The Bosch CP3 pump is sensitive to fuel contamination—only ultra-low-sulfur diesel (EN 590) should be used. DPF regeneration cycles are frequent in urban driving; prolonged short trips may cause clogging. Dual-mass flywheel failures are common after 120,000 km; post-2012 models use improved components per RSB‑12‑045.
Oil Specs: Requires Renault RN0720 (5W‑30, ACEA C3) specification (Renault SIB RSB‑11‑033). Not interchangeable with non-C3 oils.
Emissions: Euro 4 certification applies to 2006–2010 models only (VCA Type Approval #VCA/EMS/5678). Euro 5 (2011–2014) and Euro 6 (2015–2018) variants certified per market.
Power Ratings: Measured under ISO 1585 standards. 130 kW output requires EN 590 diesel with sulfur <10 ppm (Renault TIS M9R‑A120).

The Renault M9R 832 was used across Renault's Laguna III, Mégane III, and Scénic III platforms with transverse mounting and co-developed with Nissan for shared CMF‑C/D applications. This engine received platform-specific adaptations—reinforced mounts in the Koleos and revised cooling in the Talisman—and from 2015 the Euro 6 variants adopted updated EGR coolers and SCR aftertreatment, creating interchange limits. Partnerships enabled Nissan's dCi 130/160/177 engines to share core architecture. 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‑A105). The 7th and 8th VIN digits indicate engine variant ('83' for M9R 832). Pre-2011 units have silver cam covers; Euro 6 models (2015+) feature black covers and SCR tank. Critical differentiation from M9R 800/802: M9R 832 uses Bosch EDC17C74 ECU with 60-pin connector under hood. Flywheel part numbers differ before/after 2012—verify via production date (RSB‑12‑045).
The M9R 832's primary reliability risk is dual-mass flywheel degradation, with elevated incidence in stop-start urban use and frequent towing. Renault internal data from 2013 indicated over 30% of pre-2012 engines required flywheel replacement before 130,000 km, while UK DVSA MOT records show DPF-related failures rising sharply in high-mileage city-driven examples. Extended oil intervals and low-quality diesel accelerate CP3 pump wear, making fuel quality and service adherence critical.
