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.

All production years 2019–2023 meet Euro 6d standards .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M9R 868 offers strong performance and refinement with mild-hybrid assistance, but pre-late‑2021 models are prone to HPFP cam follower wear if oil changes are neglected or incorrect oil is used. Late‑2021+ revisions improved HPFP durability. Using RN0720/ACEA C5 oil and avoiding aggressive short-trip driving greatly enhance longevity.
Top issues include HPFP cam follower wear, SCR/AdBlue system faults, 48V mild-hybrid system malfunctions, and DPF ash clogging. These are documented in Renault service bulletins NTM‑18‑2020 and NTM‑10‑2021, with clear OEM repair paths.
The M9R 868 powered only the Talisman dCi 240 E-Tech Hybrid and Espace V dCi 240 Initiale Paris E-Tech Hybrid from 2019 to 2023. It was not used in non-hybrid models, smaller vehicles like Megane or Scénic, or in Nissan applications.
Aftermarket ECU tuning is common on the M9R-868 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Talisman dCi 240 E-Tech, expect ~6.9 L/100km (city) and ~5.2 L/100km (highway), or about 44 mpg UK combined. Real-world mixed driving typically returns 40–46 mpg (UK), depending on driving style, DPF regeneration frequency, and 48V system status.
Yes. The M9R series is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is generally reliable with proper maintenance.
Renault specifies SAE 0W‑30 oil meeting RN0720 or ACEA C5 standards. Using non-approved oil risks HPFP failure and increased LSPI potential. Change every 15,000 km or annually, whichever comes first.
