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 cruising. Emissions compliance for its production period was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards.
A documented reliability concern is premature failure of the EGR cooler, potentially leading to coolant contamination and overheating. This issue, referenced in Renault Service Bulletin MEG‑11‑008, is often linked to internal corrosion or clogging from carbon deposits. The design was carried over from earlier F9Q variants without significant revision.
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 VGT turbo provides accessible torque for relaxed driving but demands strict adherence to 20,000 km or 12-month oil change intervals using RN0700/RN0710 specification to protect the turbo bearings and timing chain. Ultra-low-sulfur diesel (ULSD) meeting EN 590 standards is mandatory to prevent premature high-pressure fuel pump failure. The DPF system requires periodic highway driving for passive regeneration; frequent short trips can lead to filter clogging and limp mode. EGR valve and cooler cleaning is recommended every 80,000 km to maintain emissions and performance, as per service bulletin MEG‑11‑008.
Oil Specs: Requires Renault RN0700 or RN0710 (5W-30) specification (Renault Owner's Manual). ACEA C3/C4 compliant.
Emissions: Euro 5 certification applies to all 2011–2018 models (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model applications (Renault TIS Doc. F9Q‑010).

UNECE Regulation No. 85 (Engine Power Measurement)
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.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the gearbox flange (Renault TIS F9Q‑011). The 8th VIN digit typically corresponds to the engine code ('F' for F9Q series). Visually, the engine is identifiable by its black plastic camshaft cover and the Garrett turbocharger on the exhaust manifold. Critical differentiation from the F9Q 748: The F9Q 774 uses an updated Bosch EDC17C64 ECU. Service parts, particularly for the EGR system, may have revised part numbers specific to the 774 variant.
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.
Analysis derived from Renault technical bulletins (2011-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
