The Renault M4R 704 is a 1,997 cc, inline‑four petrol engine produced between 2008 and 2015. It features dual overhead camshafts (DOHC), 16 valves, and variable valve timing (VVT) on the intake camshaft. In standard applications, it delivers 103 kW (140 PS) and 195 Nm of torque, providing a balance of responsiveness and efficiency for its class.
Fitted to models such as the Mégane III, Scénic III, and Laguna III, the M4R 704 was engineered for refined daily driving with an emphasis on mid-range flexibility. Emissions compliance for its production period was achieved through precise electronic fuel injection and catalytic conversion, meeting Euro 4 and Euro 5 standards depending on the model year and market.
One documented service concern involves the variable valve timing (VVT) solenoid, which can develop internal leaks or sticking, leading to timing errors and reduced performance. This is addressed in Renault Service Bulletin 8411A, which details diagnosis and replacement procedures for the affected component.
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 704 is a 1,997 cc inline‑four petrol engine engineered for compact and mid‑size family vehicles (2008-2015). It combines DOHC 16-valve architecture with variable valve timing to deliver smooth, linear power delivery. Designed to meet Euro 4 and Euro 5 standards, it balances everyday drivability with respectable fuel economy.

The naturally aspirated design offers predictable, linear power delivery ideal for relaxed cruising but requires higher revs for maximum performance. Adherence to 15,000 km oil change intervals with RN0700 specification oil is critical to maintain VVT solenoid function and timing chain longevity. The engine is sensitive to low-quality fuel, which can cause carbon buildup on intake valves and injectors. Pre-2011 models should have the VVT solenoid inspected if experiencing rough idle or timing-related fault codes, as per Renault SIB 8411A. The timing chain is designed for the engine's life but should be inspected if unusual noise is present.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault SIB 8411A). Equivalent ACEA A3/B4 oils are acceptable.
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 model range (Renault TIS Doc. M4R-002).

The Renault M4R 704 was used across Renault's Mégane III and Laguna III platforms with transverse mounting. This engine received platform-specific adaptations-slightly different engine mounts for the Scénic III-but no major facelift revisions occurred during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, near the gearbox flange (Renault TIS M4R-001). The 8th VIN digit typically corresponds to the engine code 'M'. Visually, the engine is identified by its black plastic intake manifold and the "16V" badge on the cam cover. Critical differentiation from the turbocharged M4R 760: The M4R 704 lacks a turbocharger and associated piping. Service parts are generally compatible across all model years, though ECU software versions may differ.
The M4R 704's primary documented service concern is variable valve timing (VVT) solenoid failure, with elevated incidence in vehicles subjected to extended oil change intervals. Renault internal data indicates this was a common cause for workshop visits on early-build engines, while UK DVSA records show no systemic emissions failures linked to this engine. Neglecting oil service intervals significantly increases the risk of solenoid malfunction.
Analysis derived from Renault technical bulletins (2008-2015) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
