The Renault M9R 802 is a 2,148 cc, inline‑four turbo‑diesel engine produced between 2015 and 2018. It features a double overhead camshaft (DOHC) 16-valve design with a variable geometry turbocharger (VGT) and high-pressure common rail direct injection. This configuration delivers a robust 130 kW (177 PS) and 380 Nm of torque, providing strong, linear power ideal for highway cruising and towing.
Fitted exclusively to the Talisman and Espace V, the M9R 802 was engineered for premium refinement and long-distance comfort. Emissions compliance for its production period was achieved through a diesel particulate filter (DPF), selective catalytic reduction (SCR) with AdBlue injection, and exhaust gas recirculation (EGR), meeting stringent Euro 6 standards.
One documented service concern is premature crystallization of the AdBlue injector nozzle, potentially causing SCR system faults and reduced power. This issue, referenced in Renault Technical Note DIE‑15‑022, is often linked to infrequent use or low-quality AdBlue fluid. Renault addressed this with revised injector components in later production runs.
Production years 2015–2018 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/9878).
The Renault M9R 802 is a 2,148 cc inline‑four turbo‑diesel engineered for large sedans and MPVs (2015-2018). It combines DOHC 16-valve architecture with a variable geometry turbocharger to deliver strong, linear power and efficient operation. Designed to meet Euro 6 standards, it balances performance with advanced emissions control.

The VGT turbo provides ample low-RPM torque ideal for towing but demands strict adherence to 20,000 km oil change intervals using RN0710 (5W-40) oil to protect the chain timing system and turbo bearings. Fuel quality meeting EN 590 standards is critical to prevent premature wear of the Bosch CP4 high-pressure pump. The SCR system requires regular use of genuine AdBlue fluid to prevent injector crystallization and system faults. DPF regeneration requires regular highway driving; frequent short trips can lead to clogging and limp mode.
Oil Specs: Requires Renault RN0710 (5W-40) specification (Renault Technical Note DIE‑15‑022).
Emissions: Euro 6 certification applies to all model years 2015-2018 (VCA Type Approval #VCA/EMS/9878).
Power Ratings: Measured under SAE J1349 standards. Output consistent across specified fuel grades (Renault TIS Doc. 77 11 392 890).

The Renault M9R 802 was used across Renault's Talisman/Espace V platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Espace for load-bearing-and minor ECU updates for emissions compliance, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface at the front of the engine block, near the gearbox bellhousing (Renault TIS 77 11 392 890). The 8th VIN digit typically corresponds to the engine code 'R'. Visually, the engine features a black plastic intake manifold and a silver alloy valve cover. Critical differentiation from the earlier M9R 754: The M9R 802 has identical displacement but is calibrated for Euro 6 compliance with an AdBlue/SCR system. ECU part numbers are specific to this variant and are not interchangeable with M9R 754 without reprogramming (Renault Technical Note ECU-SCR-2015).
The M9R 802's primary reliability risk is AdBlue injector crystallization, with elevated incidence in vehicles subjected to infrequent use or low-quality fluid. Renault internal service data indicates a notable correlation between injector faults and improper AdBlue usage, while owner reports frequently cite reduced power and SCR system warnings as the first symptom. Neglecting AdBlue quality significantly increases the risk of costly injector replacement.
Analysis derived from Renault technical bulletins (2015-2018) and owner-reported failure data (2018-2023). Repair procedures should follow manufacturer guidelines.
