The Renault M4R 713 is a 1,997 cc, inline‑four naturally aspirated petrol engine produced between 2008 and 2015. It features dual overhead camshafts (DOHC), 16 valves, and variable valve timing (VVT) on the intake camshaft. This architecture delivers a balance of 103 kW (140 PS) and 195 Nm of torque, with VVT optimizing efficiency across the rev range.
Fitted to models such as the Laguna III, Mégane III, and Scénic III, the M4R 713 was engineered for refined, everyday drivin…
Production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault M4R 713 is a 1,997 cc inline‑four naturally aspirated petrol engine engineered for mid‑size sedans and MPVs (2008-2015). It combines DOHC 16-valve architecture with variable valve timing to deliver smooth, linear power delivery and efficient operation. Designed to meet Euro 5 standards, it balances everyday drivability with respectable fuel economy.

The Renault M4R 713 was used across Renault's Laguna III/Mégane III platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Laguna for NVH refinement-and from 2012 minor ECU updates for emissions compliance, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
The M4R 713's primary reliability risk is variable valve timing actuator failure, with elevated incidence in vehicles subjected to extended oil change intervals. Renault internal service data indicates a notable correlation between actuator faults and non-compliant oil usage, while owner reports frequently cite rough idle as the first symptom. Neglecting oil changes significantly increases the risk of costly actuator replacement.
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 M4R 713 is generally a robust and reliable engine when maintained correctly. Its main weakness is the variable valve timing actuator, which fails prematurely if oil changes are neglected or the wrong oil is used. With strict adherence to Renault's 15,000 km service schedule and RN0700 oil, the engine can easily exceed 200,000 km without major issues.
The most frequent issues are variable valve timing actuator failure (causing rough idle), high-pressure fuel pump failure (preventing start), ignition coil pack failure (causing misfires), and oil leaks from the valve cover gasket. These are well-documented in Renault service bulletins and owner forums.
The M4R 713 2.0L petrol engine was primarily used in the Renault Laguna III (2008-2015), Mégane III (2009-2015), and Scénic III (2009-2015). It was typically found in mid-range trims like Expression and Dynamique, offering a balance of performance and efficiency for these models.
Yes, but gains are modest due to its naturally aspirated design. ECU remaps can yield an extra 8-12 kW by optimizing fuel and ignition timing. More significant power increases require forced induction (turbo/supercharger), which is complex and costly. Most owners focus on improving throttle response rather than peak power.
Real-world fuel economy is respectable for its era. Expect around 8.5 L/100km (33 mpg UK) in mixed driving for a Laguna or Scénic, and slightly better, around 7.8 L/100km (36 mpg UK), in the lighter Mégane. Highway cruising can return figures close to 6.5 L/100km (43 mpg UK).
Yes. The M4R 713 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Renault mandates the use of RN0700 specification oil, typically SAE 5W-40 viscosity. Using this specific oil is crucial for the longevity of the variable valve timing system. Always use a high-quality, fully synthetic oil that meets this standard and change it every 15,000 km or annually.
