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 ref…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M9R 761 is generally robust with strong torque, but its Achilles' heel is the high-pressure fuel pump. Failures are often linked to poor fuel quality. With strict adherence to using premium diesel and timely fuel filter changes, the engine can be very reliable. Regular AdBlue system maintenance is also crucial for long-term trouble-free operation.
The most frequent issues are high-pressure fuel pump (HPFP) failures, AdBlue/SCR system faults leading to limp mode, EGR valve clogging, and turbocharger actuator problems. These are well-documented in Renault service bulletins and owner reports, with HPFP failure being the most costly repair.
The M9R 761 was primarily used in the second-generation Koleos (2016-2020), the Talisman sedan (2015-2019), and the fifth-generation Espace (2015-2019). It was offered in dCi 160, dCi 175, and dCi 190 power outputs. It is closely related to the Nissan R9M engine.
Yes, the M9R 761 responds well to ECU remapping. Stage 1 tunes can safely increase power by 20-30 kW and torque by 50-70 Nm. The engine's internals are strong, but supporting modifications like a larger intercooler are recommended for higher stages. Tuning can increase stress on the HPFP, so fuel quality becomes even more critical.
Official combined figures range from 5.2 to 5.8 L/100km (approx. 49-54 mpg UK) depending on the model and trim. Real-world consumption is typically higher, averaging 6.5-7.5 L/100km (38-43 mpg UK) in mixed driving. Highway cruising can yield figures closer to the official numbers.
Yes. The M9R 761 is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal damage. Fortunately, the front-mounted timing chain is very durable and rarely fails if oil is changed regularly.
Renault mandates the use of RN17 specification 5W-30 synthetic oil. This specific formulation is designed to protect the high-pressure fuel pump and emissions systems. Using the correct oil and adhering to the 20,000 km or 12-month service interval is vital for engine longevity.
