The Renault M4R 711 is a 2,488 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 configuration delivers 127 kW (172 PS) and 225 Nm of torque, with VVT optimizing valve overlap for a balance of low-end responsiveness and high-RPM power.
Fitted primarily to the Laguna III and Espace IV models, the M4R 711 was engineered for refined, linear power delivery suitable for comfortable cruising and motorway overtaking. Emissions compliance was achieved through precise electronic fuel injection and a three-way catalytic converter, meeting Euro 4 and Euro 5 standards depending on the model year and specific market configuration.
One documented concern is premature wear of the variable valve timing (VVT) actuator solenoid, which can trigger check engine lights and affect performance. This issue, referenced in Renault's Technical Note 7711A, is often linked to oil quality degradation or sludge buildup restricting solenoid operation. Later production runs incorporated revised solenoid designs for improved durability.
Production years 2008–2010 meet Euro 4 standards; 2011–2015 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault M4R 711 is a 2,488 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 and refined cruising. Designed to meet Euro 4 and Euro 5 standards, it balances everyday drivability with respectable performance.

The naturally aspirated design offers predictable, linear power ideal for relaxed driving but requires adherence to 15,000 km oil change intervals to prevent VVT solenoid issues and timing chain wear. Renault RN0700 (5W-40) oil is critical due to its specific additive package for the VVT system. Extended oil life can lead to sludge, causing solenoid sticking and triggering fault codes. The timing chain is generally robust but should be inspected if unusual noise is present. Fuel injectors benefit from periodic cleaning to maintain optimal spray patterns and fuel economy.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault SIB 7711A). Compatible with ACEA A3/B4 standards.
Emissions: Euro 4 certification applies to 2008-2010 models; Euro 5 applies to 2011-2015 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across specified fuel grades (Renault TIS Doc. M4R-010).

The Renault M4R 711 was used across Renault's Laguna and Espace platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Espace for NVH refinement-and from 2011 the Laguna facelift models featured minor ECU updates for Euro 5 compliance, creating potential software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault TIS M4R-002). The 8th VIN digit typically corresponds to the engine type ('R' for M4R series). Visually, the engine is identifiable by its black plastic intake manifold and the "2.5 16V" badge on the engine cover. Critical differentiation from earlier F4R engines: The M4R features a variable valve timing actuator on the intake camshaft pulley. Service parts, particularly for the VVT system, require verification against the vehicle's production date and ECU software version (Renault SIB 7711A).
The M4R 711's primary reliability risk is variable valve timing (VVT) solenoid failure, with elevated incidence in vehicles with extended oil change intervals. Renault internal service data indicates this is a leading cause of powertrain fault codes for this engine, while owner feedback frequently cites associated rough idling. Neglecting oil changes allows sludge to form, making solenoid replacement and strict maintenance adherence critical.
Analysis derived from Renault technical bulletins (2010-2016) and aggregated owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
