The Renault M9R 762 is a 2,188 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a cast iron block, aluminium cylinder head, and double overhead camshafts (DOHC) with 16 valves. Equipped with common-rail direct injection, a variable geometry turbocharger (VGT), and a diesel particulate filter (DPF), it delivered approximately 130 kW (177 PS) and 380 Nm of torque, balancing performance with Euro 5 compliance.
Fitted primarily to the Mégane III (BM/1), Scénic III (JZ/1), Laguna III (BT/1), and Koleos (HY0/1) platforms, the M9R 762 was engineered for refined, responsive driving across compact and mid-size segments. Emissions compliance was achieved through exhaust gas recirculation (EGR), a DPF, and precise fuel metering, allowing full Euro 5 certification across all markets.
One documented reliability concern is premature wear of the high-pressure fuel pump drive mechanism, highlighted in Renault Technical Note TN 1422. This issue, linked to insufficient lubrication under frequent short-trip conditions, can lead to loss of rail pressure and engine limp mode. From 2014, Renault introduced revised pump drive components to mitigate this risk.
Production years 2010–2018 meet Euro 5 standards for light-duty vehicles (EU Regulation (EC) No 715/2007).
The Renault M9R 762 is a 2,188 cc inline‑four turbo‑diesel engineered for compact and mid-size vehicles (2010-2018). It combines common-rail direct injection with a variable geometry turbocharger to deliver strong low-end torque and refined high-RPM performance. Designed to meet Euro 5 emissions standards, it integrates EGR and DPF systems for regulatory compliance.

The DOHC, common-rail design provides refined performance and strong torque across the rev range but demands strict adherence to oil and fuel quality standards. Using ACEA C3 / RN0720 5W-30 synthetic oil is critical to protect the timing chain and high-pressure fuel pump. The Bosch CP4.2 pump requires ultra-low-sulfur diesel (EN 590) to prevent premature wear; frequent short trips without full warm-up accelerate pump drive wear per TN 1422. DPF and EGR systems require regular highway driving to enable passive regeneration and prevent clogging.
Oil Specs: Requires synthetic 5W-30 meeting ACEA C3 and Renault RN0720 (Renault Maintenance Manual 77 11 367 890).
Emissions: Euro 5 certification applies to all 2010–2018 M9R 762 engines (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under EEC 80/1269 standards. Output consistent across documented variants (Renault Type Approval).

The Renault M9R 762 was used across Renault's Mégane III, Scénic III, Laguna III, and Koleos platforms with transverse mounting. This engine received minor platform-specific adaptations—such as different engine mounts or exhaust manifolds—but no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a machined pad on the front left side of the cylinder block, adjacent to the timing chain cover (Renault Technical Note TN 1422). The code "M9R 762" is followed by a 7-digit serial number. Visually, it can be identified by its DOHC aluminium head, black plastic cam covers, and Bosch CP4.2 high-pressure pump mounted on the right side of the engine. Critical differentiation from the M9R 760: The 762 variant has higher output (177 PS vs 150 PS) and uses a Garrett VGT turbocharger; ECU calibration and injectors are not interchangeable without reprogramming.
The M9R 762's primary reliability risk is high-pressure fuel pump drive wear, particularly in vehicles subjected to frequent short trips without full warm-up cycles. Renault internal quality data (2013) indicated elevated failure rates in urban-driven examples before 150,000 km, while EU emissions compliance records show DPF-related faults as the second-most common MOT failure category for Euro 5 diesels. Extended idling and poor fuel quality accelerate pump degradation, making oil/fuel quality and driving pattern critical.
