The Renault M9R 761 is a 2,299 cc, inline‑four turbo‑diesel engine produced between 2015 and 2020. It features a high-pressure common-rail fuel system, a variable geometry turbocharger (VGT), and double overhead camshafts. This engine was designed for robust performance in larger SUVs and vans, delivering outputs between 120 kW (163 PS) and 140 kW (190 PS) with torque figures of 380–400 Nm.
Fitted primarily to the Koleos II and Talisman, the M9R 761 was engineered for refined, effortless cruising and strong towing capability. Emissions compliance for Euro 6 standards was achieved through a combination of exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection.
One documented concern involves the high-pressure fuel pump, which can suffer from premature wear leading to starting difficulties or power loss. This issue, referenced in Renault Technical Note MEC 007 (03/2018), is often linked to fuel contamination or inadequate filtration. Renault addressed this with revised pump components and updated fuel filter service intervals.
Production years 2015–2020 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9R 761 is a 2,299 cc inline‑four turbo‑diesel engineered for mid‑size SUVs and executive sedans (2015-2020). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong, linear torque and refined highway performance. Designed to meet Euro 6 standards, it balances power with stringent emissions control.

The VGT turbo provides strong, linear torque ideal for highway cruising and towing but demands strict adherence to 20,000 km or 12-month oil change intervals to protect the turbo and chain. Renault RN17 5W-30 oil is critical for its specific additive package protecting the high-pressure fuel system. The Bosch CP4 pump requires ultra-low-sulfur diesel (ULSD) meeting EN 590 standards; contaminated fuel is a primary cause of pump failure per Renault Technical Note MEC 007. The AdBlue/SCR system requires periodic refills and sensor checks to maintain emissions compliance and prevent engine de-rating.
Oil Specs: Requires Renault RN17 specification (Renault Service Bulletin SB-02-2019).
Emissions: Euro 6 certification applies to all 2015-2020 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output varies by model calibration (Renault Group PT-2020).

The Renault M9R 761 was used across Renault's CMF-CD platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Koleos for off-road durability-and shared its core architecture with the Nissan R9M engine found in the Qashqai and X-Trail. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a plate riveted to the left-side cylinder head, near the intake manifold (Renault TIS MEC 001). The 8th VIN digit typically indicates engine displacement ('2' for 2.3L). The M9R 761 can be visually identified by its black plastic engine cover with "dCi" branding and the presence of an AdBlue tank filler cap near the fuel filler. Critical differentiation from earlier M9R variants: The 761 features a revised ECU (Bosch EDC17C84) and a larger intercooler. Service parts for the fuel system are specific to the CP4 pump and are not interchangeable with CP3-equipped engines.
The M9R 761's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using poor-quality fuel. Renault internal reports from 2019 noted a cluster of pump failures around the 80,000 km mark, while owner feedback frequently cites starting issues as the first symptom. Fuel quality and filter maintenance are critical preventative measures.
