The Renault F4R 774 is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 2008 and 2015. It features a dual overhead camshaft (DOHC) design with 16 valves and variable valve timing (VVT) on the intake camshaft. This configuration, known as “Energy,” prioritizes smooth power delivery and mid — range responsiveness for everyday drivability.
Fitted to models such as the Laguna III, Mégane III, and Scénic III, the F4R 774 was engineered for refined cr…
Production years 2008–2015 meet Euro 5 standards .
The Renault F4R 774 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for mid‑size family vehicles (2008-2015). It combines DOHC 16-valve architecture with intake variable valve timing to deliver smooth, linear power and responsive mid-range torque. Designed to meet Euro 5 standards, it balances everyday drivability with acceptable fuel economy.

The Renault F4R 774 was used across Renault's Laguna III and Mégane/Scénic III platforms with transverse mounting and no external licensing. This engine received minor ECU calibrations for different model weights but no significant mechanical revisions, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The F4R 774's primary reliability risk is Variable Valve Timing (VVT) system failure, with elevated incidence in vehicles subjected to extended oil change intervals. Renault internal data indicates a correlation between oil degradation and solenoid/phaser faults, while owner reports frequently cite rough idle as the first symptom. Neglecting oil service makes VVT component replacement critical.
Analysis derived from Renault technical bulletins (2010-2016) and owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The F4R 774 is generally reliable with a robust chain-driven timing system. Its main weakness is the VVT system, which is sensitive to oil quality and change intervals. With strict adherence to using RN0700/RN0710 oil and servicing every 15,000 km, it can easily surpass 200,000 km without major issues.
The most frequent issues are VVT solenoid or phaser failure (causing rough idle), ignition coil pack failures (causing misfires), and minor oil leaks from the valve cover gasket. High-pressure fuel pump failure is possible but less common. These are covered in Renault service documentation.
This 2.0L petrol engine was used in the third-generation Laguna (2008-2015), third-generation Mégane (2008-2015), and third-generation Scénic (2009-2015), all badged as '2.0 Energy'. It was not used in Clio, Captur, or Kadjar models, nor was it licensed to other manufacturers.
Yes, but gains are modest due to its naturally aspirated design. ECU remaps can yield 5-10 kW by optimizing ignition and fuel maps. Significant power increases require forced induction (turbo/supercharger kits), which is complex and costly. Most tuning focuses on improving throttle response rather than peak power.
Real-world fuel economy is moderate for its era. Expect around 8.5-9.5 L/100km (30-33 mpg UK) in mixed driving for a Laguna, and 7.5-8.5 L/100km (33-38 mpg UK) for a Mégane or Scénic. Highway cruising can return 6.5-7.0 L/100km (40-43 mpg UK).
Yes. The F4R 774 is an interference engine. If the timing chain were to fail catastrophically (e.g., tensioner failure causing the chain to jump), the pistons would collide with the open valves, resulting in severe internal engine damage requiring a rebuild.
Renault mandates the use of RN0700 or RN0710 specification oil, typically a 5W-40 synthetic or semi-synthetic. Using the correct oil is paramount for the longevity of the VVT system and timing chain tensioner. Change intervals should not exceed 15,000 km or 12 months.
