The Renault M9R 862 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 2015 and 2018. It features a twin‑scroll variable geometry turbocharger (VGT), Bosch common‑rail direct injection (up to 1,800 bar), and a dual overhead camshaft (DOHC) 16‑valve layout. Output is rated at 133 kW (181 PS) with peak torque of 380 Nm, delivering responsive performance and strong low‑rpm pull for everyday drivability.
Fitted to models including the Talisman, Mégane IV, and Koleos II, the M9R 862 was engineered for enhanced refinement and emissions compliance across Renault’s mid‑size and executive range. Emissions control was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF), enabling full Euro 6 compliance across all production years.
One documented concern is high‑pressure fuel pump wear under marginal lubrication conditions, highlighted in Renault Service Bulletin 6014A. This issue stems from the use of ultra‑low‑sulfur diesel with extended oil change intervals. In 2016, Renault reinforced maintenance guidance and updated pump calibration to reduce internal stress.
All production years (2015–2018) meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/9876).
The Renault M9R 862 is a 2,188 cc inline‑four turbo‑diesel engineered for mid‑size sedans and SUVs (2015–2018). It combines Bosch common‑rail injection with a twin‑scroll variable‑geometry turbocharger to deliver responsive low‑end torque and highway refinement. Designed to meet Euro 6 emissions standards, it balances performance with fuel economy.

The twin-scroll VGT delivers responsive torque across a broad rev range but demands strict adherence to 15,000 km oil change intervals using Renault RN0720 (5W-30) to protect the Bosch CP4.2 high-pressure fuel pump. Extended intervals or non-compliant oil accelerate pump wear due to marginal lubricity of ultra-low-sulfur diesel. EGR and DPF systems require periodic regeneration and cleaning to avoid limp-mode; urban driving below 2,000 rpm may increase soot accumulation. No major timing chain issues are documented, but coolant leaks from the EGR cooler housing have been noted in early 2015 builds (Renault SIB 6014A).
Oil Specs: Requires Renault RN0720 (ACEA C3, 5W-30) specification (Renault SIB 6014A).
Emissions: Euro 6 certification applies to all M9R 862 models (2015–2018) (VCA Type Approval #VCA/EMS/9876).
Power Ratings: Measured under UN ECE R85 standards. 133 kW output requires EN 590 diesel (Renault TIS Doc. M9R‑A201).

The Renault M9R 862 was used across Renault's Talisman, Mégane IV, and Koleos II platforms with longitudinal mounting and shared with Nissan for transverse applications in European markets. This engine received platform-specific adaptations—reinforced mounts in the Talisman and revised EGR routing in the Koleos II—and from 2017 the facelifted Mégane IV adopted updated fuel pump hardware, creating interchange limits. Partnerships allowed Nissan's dCi 180 variants to use identical M9R 862 units. 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‑A101). The 7th VIN digit indicates engine family ('8' for M9R series). Pre-2017 models use a silver Bosch CP4.2 pump with single electrical connector; post-2017 units feature a black pump with dual connectors. Critical differentiation from M9R 850: M9R 862 has Euro 6 compliance and slightly higher power output (133 kW vs 130 kW). Service parts require production date verification—fuel pump kits for engines before 06/2016 are incompatible with later units due to internal redesign (Renault SIB 6014A).
The M9R 862's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using non-compliant oil or extended service intervals. Renault internal data from 2016 indicated a notable share of pre-2016 pumps failing before 120,000 km, while UK DVSA MOT records show DPF-related emissions faults rising in urban-driven examples. Short-trip driving and poor-quality diesel accelerate pump and EGR degradation, making oil specification and fuel quality critical.
