The Renault F9Q 774 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2011 and 2018. It features a DOHC valvetrain, common rail direct injection, and a variable geometry turbocharger (VGT), delivering outputs of 96 kW (130 PS) with peak torque of 320 Nm. Its cast iron block provides durability for high — mileage use.
Fitted primarily to the Megane III Phase 2 and Scénic III Phase 2, the F9Q 774 was engineered for responsive low — end torque and fuel — efficient cru…
Production years 2011–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6789).
The Renault F9Q 774 is a 1,870 cc inline‑four turbo‑diesel engineered for compact MPVs and hatchbacks (2011-2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑ to mid‑rpm torque and efficient highway cruising. Designed to meet Euro 5 standards, it balances performance with fuel economy.

The Renault F9Q 774 was used across Renault's Megane III/Scénic III platforms with transverse mounting. This engine received platform-specific adaptations-different intake manifolds for the Scénic-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
The F9Q 774's primary reliability risk is EGR cooler failure, with elevated incidence in vehicles operating in stop-start traffic. Renault internal reports from 2014 indicated a significant number of warranty claims for cooler replacement before 120,000 km, while UK DVSA data shows related coolant system faults as a common MOT advisory item. Extended low-speed driving accelerates carbon buildup, making service adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F9Q 774 is generally robust with its cast iron block, but its longevity depends heavily on maintenance. The EGR cooler is a known weak point, especially in urban driving. Using high-quality diesel and adhering to strict oil change intervals (20,000 km) with RN0700/RN0710 oil is crucial for long-term reliability beyond 200,000 km.
The most frequent issues are EGR cooler failures leading to coolant contamination, DPF clogging from short trips, and high-pressure fuel pump wear. Turbo actuator linkage sticking is also common. These are well-documented in Renault service bulletins and owner reports.
This 1.9 dCi engine was primarily used in the Renault Megane III Phase 2 (2011-2016) and Scénic III Phase 2 (2012-2018) in the 130 PS variant. It is a later evolution of the F9Q family designed for Euro 5 compliance.
Yes, the F9Q 774 responds well to ECU remapping. Stage 1 tunes can safely increase power to 150-160 PS and torque to 360-380 Nm. The stock internals are generally strong enough for these gains. Further power requires upgraded turbo and injectors. Always use supporting modifications and high-quality fuel.
Fuel economy is very good. In a Megane III 1.9 dCi 130, expect around 5.5 L/100km (51 mpg UK) combined. Real-world figures depend heavily on driving style, DPF regeneration cycles, and the condition of the EGR system.
Yes. The F9Q 774 is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the front-mounted chain is generally reliable with proper oil changes.
Renault mandates the use of RN0700 or RN0710 specification oil, typically a 5W-30 synthetic. This specific formulation is designed for the engine's emissions systems (DPF, EGR) and provides necessary protection for the turbocharger and timing chain. Using the correct oil is non-negotiable for reliability.
