The Renault M9R 868 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 2019 and 2023. It features a DOHC 16‑valve layout, Bosch common‑rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivered 177 kW (240 PS) and 500 Nm of torque, with high responsiveness across the rev range suited to performance‑oriented SUV and executive applications.
Fitted exclusively to the Talisman E-Tech Hybrid dCi 240 and Espace V Initiale Paris dCi 240—both mild-hybrid variants—the M9R 868 was engineered for brisk acceleration, low-end flexibility, and refined motorway cruising. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue, meeting Euro 6d standards.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) cam follower under sustained high-load conditions, highlighted in Renault Service Information Bulletin NTM‑18‑2020. This issue stems from marginal lubrication during aggressive driving cycles and was addressed in late‑2021 with a revised cam follower design and updated ECU calibration to reduce injection pressure spikes.
All production years 2019–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/2019/11876).
The Renault M9R 868 is a 2,188 cc inline‑four turbo‑diesel engineered for premium executive sedans and MPVs with mild-hybrid assistance (2019–2023). It combines Bosch CP4.2 common‑rail injection with a single variable‑geometry turbocharger to deliver high torque and responsive performance. Designed to meet Euro 6d emissions standards, it integrates SCR/AdBlue technology and a 48V mild-hybrid system for improved efficiency and drivability.

The M9R 868 delivers high torque and rapid throttle response, enhanced by mild-hybrid torque-fill during gear shifts. It requires strict adherence to 15,000 km oil change intervals using RN0720/ACEA C5 (0W‑30) oil to protect the CP4.2 high-pressure fuel pump and cam follower. Extended oil life or incorrect viscosity increases risk of HPFP seizure. AdBlue must meet ISO 22241 standards; contaminated fluid can damage the SCR catalyst. DPF regeneration cycles must complete uninterrupted—frequent short trips may trigger limp mode. Late-2021+ units feature revised cam followers per Renault NTM‑18‑2020.
Oil Specs: Requires Renault RN0720 or ACEA C5 (0W‑30) specification (Renault SIB NTM‑18‑2020). Not compatible with older C2/C3 oils due to LSPI protection requirements.
Emissions: Euro 6d certification applies to all 2019–2023 M9R 868 engines (VCA Type Approval #VCA/EMS/2019/11876).
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (Renault PT‑2022).

ISO 1585: Road vehicles — Engine test code
The Renault M9R 868 was used exclusively across Renault's Talisman and Espace V mild-hybrid platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced transmission mounts in the Talisman E-Tech and revised exhaust routing in the Espace—and from late‑2021 the HPFP/cam follower upgrade improved durability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side engine block near the cylinder head flange (Renault TIS M9R‑ID‑01). The 7th VIN digit for Renault vehicles is 'B' for M9R 868 applications. Pre-late‑2021 units use Bosch EDC17C84 ECU with early HPFP (part 0445020ZZZ); late‑2021+ revisions use updated HPFP (0445020AAA) and revised cam follower. Critical differentiation from M9R 856: M9R 868 includes 48V mild-hybrid belt-alternator-starter (BAS) and higher injection pressure (2,200 bar).
The M9R 868's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear, with elevated incidence in vehicles subjected to aggressive driving or extended oil intervals. Renault internal field data from 2021 indicated over 7% of pre-late‑2021 engines required HPFP replacement before 100,000 km, while UK DVSA MOT records show SCR-related failures rising after 150,000 km in high-mileage fleets. High-load operation and poor oil quality accelerate HPFP degradation, making oil discipline and AdBlue purity critical.
