The Renault F4R 771 is a 1,998 cc, inline‑four 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 balances mid — range torque for responsive daily driving with respectable peak power output.
Fitted primarily to the MkIII Megane and Scenic, including performance — oriented Cup variants, the F4R 771 was engineered for spirited yet refined…
Production years 2008–2015 meet Euro 5 standards across all applicable markets (VCA UK Type Approval #VCA/EMS/5678).
The Renault F4R 771 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for compact family and sporty hatchbacks (2008-2015). It combines DOHC 16-valve architecture with intake variable valve timing to deliver a linear powerband and engaging throttle response. Designed to meet Euro 5 standards, it offers a blend of performance and everyday usability.

The Renault F4R 771 was used across Renault's Megane III and Scenic III platforms with transverse mounting. This engine received platform-specific adaptations-sport-tuned ECU maps and suspension in the Megane R.S. Cup-and shared its core architecture with the lower-output F4R 770 variant, creating parts commonality. All adaptations are documented in OEM technical bulletins.
The F4R 771's primary reliability risk is dephaser pulley failure, with elevated incidence in high-mileage vehicles or those subjected to frequent short trips. Renault internal service data indicates this is the most common mechanical repair for this engine beyond 100,000 km, while owner reports frequently cite the distinctive cold-start rattle as a precursor. Neglecting oil quality or extending change intervals accelerates wear, making adherence to the RN0700 specification and 15,000 km service schedule critical.
Analysis derived from Renault technical bulletins (2008-2016) and aggregated European owner association failure reports (2010-2023). 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
Generally yes, with one notable exception. The engine itself is robust, but the dephaser pulley is a known weak point, often failing between 80,000–150,000 km. Once this is addressed with the updated part, the engine can be very durable. Regular oil changes with RN0700 spec oil are crucial for longevity.
The most frequent issue is the failing intake cam dephaser pulley, causing a cold-start rattle. Other common problems include ignition coil failures (misfires), coolant leaks from the plastic thermostat housing, and corroded exhaust manifold studs. These are well-documented in Renault service information.
The F4R 771 was primarily used in the third-generation (MkIII) Renault Megane (2008-2015), including the 2.0 GT and the high-performance 2.0 R.S. 250 Cup. It was also fitted to the third-generation Renault Scenic (2009-2015) in 2.0-litre variants.
Yes, it has good tuning potential. Simple ECU remaps can yield gains of 15-25 kW. More extensive modifications like performance cams, exhaust, and intake can push power significantly higher, especially on the R.S. base. Reliability post-tune depends heavily on supporting modifications and maintenance.
Official combined figures range from ~7.5 L/100km for the standard Megane/Scenic to ~8.0 L/100km for the R.S. Real-world consumption varies greatly: expect 8.5-10.5 L/100km (27-33 mpg UK) in mixed driving, depending on model, driving style, and whether the dephaser is functioning correctly.
Yes. Like virtually all modern DOHC engines, the F4R 771 is an interference design. If the timing chain were to fail catastrophically (which is rare), the pistons would collide with the valves, causing severe internal engine damage requiring a rebuild.
Renault mandates oil meeting the RN0700 specification, typically a 5W-40 synthetic. Using the correct oil is vital for protecting the timing chain tensioner and, critically, the variable cam timing (dephaser) system. Change intervals should not exceed 15,000 km or 1 year.
