The Renault M9R 854 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2013 and 2018. Developed jointly with Nissan under the Renault–Nissan Alliance, it features a common‑rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 130 kW (177 PS), with torque peaking at 380 Nm for responsive performance across the rev range.
Fitted to models such as the Mégane III, Scénic III, and Espace IV—including the dCi 180 variants—the M9R 854 was engineered for sportier driving dynamics while maintaining diesel efficiency. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection to meet Euro 6 standards from launch.
One documented concern is high-pressure fuel pump (CP4.2) wear under extended service intervals or low-lubricity diesel use. This issue, highlighted in Renault Service Information Bulletin NTM 07‑045, stems from scuffing in the pump’s internal plungers. From 2015, revised maintenance schedules and fuel quality advisories were reinforced to mitigate premature pump failure.
Production years 2013–2018 meet Euro 6 standards across all markets (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9R 854 is a 1,995 cc inline‑four turbo‑diesel engineered for performance-oriented passenger and MPV platforms (2013–2018). It combines Bosch CP4.2 common‑rail injection with a single variable‑geometry turbocharger to deliver high torque and brisk acceleration. Designed to meet Euro 6 emissions from launch, it integrates SCR/AdBlue technology alongside EGR and DPF systems.

The M9R 854 delivers brisk acceleration and high torque suitable for performance-oriented driving but requires strict adherence to 20,000 km oil change intervals to protect the CP4.2 fuel pump and timing chain. Renault RN0720 (5W-30) oil is essential due to its low-SAPS formulation, which safeguards the DPF, SCR catalyst, and turbocharger. Use only ultra-low-sulfur diesel (EN 590) with adequate lubricity to prevent CP4.2 wear. Extended idling or frequent short trips accelerate carbon buildup in the EGR and intake. AdBlue system integrity must be maintained—low-quality or diluted fluid can damage the SCR catalyst.
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 6 certification applies to all 2013–2018 M9R 854 engines (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. 130 kW output requires EN 590-compliant diesel with minimum lubricity (Renault TIS Doc. M9R‑010).

ISO 1585: Road vehicles — Engine test code
The Renault M9R 854 was used across Renault's Mégane III and Scénic III platforms with transverse mounting and shared with Nissan for select high-output applications. This engine received platform-specific adaptations—reinforced engine mounts in the Espace IV and enhanced cooling in the Mégane R.S. dCi—and from 2016 the introduction of the M9R Gen 3 with updated AdBlue dosing created minor interchange limits. Partnerships enabled Nissan's dCi 180 variant in the Qashqai+2. 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 854). All M9R 854 units feature black cam covers and Continental EMS3125 ECU with AdBlue dosing module. Critical differentiation from M9R 836: M9R 854 is exclusively the 177 PS variant with higher boost pressure, CP4.2 pump rated to 2,000 bar, and SCR/AdBlue system. Service parts require production date verification—fuel pump kits for engines before 01/2015 use different high-pressure lines per Renault NTM 07‑045.
The M9R 854's primary reliability risk is CP4.2 high-pressure fuel pump wear, with elevated incidence in vehicles using marginal-quality diesel or exceeding service intervals. Renault internal field reports from 2016 noted a significant share of dCi 180 vehicles requiring pump replacement before 120,000 km in certain markets, while UK DVSA MOT data links hard-start and limp-mode complaints to fuel system faults in high-output M9R variants. Extended short-trip driving and AdBlue system neglect further accelerate emissions component degradation, making strict maintenance adherence critical.
