The Renault M4R 714 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 configuration delivers a balance of 103 kW (140 PS) and 195 Nm of torque, with VVT optimizing valve overlap for improved low-end response and fuel efficiency.
Fitted to models such as the Laguna III, Mégane III, and Scénic III, the M4R 714 was engineered for refined, economical cruising and responsive urban driving. Emissions compliance was achieved through precise electronic fuel injection and catalytic conversion, meeting Euro 5 standards for its entire production run.
One documented concern is premature wear of the variable valve timing (VVT) solenoid or phaser, potentially causing rough idle or timing-related fault codes. This issue, referenced in Renault Technical Note MEC 08A, is often linked to oil quality degradation or infrequent changes affecting solenoid operation. Renault addressed this with updated solenoid part numbers for service replacements.
Production years 2008–2015 meet Euro 5 standards for all markets (EU Regulation (EC) No 715/2007).
The Renault M4R 714 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 good fuel economy. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The DOHC with VVT provides smooth, linear power ideal for daily commuting but requires strict adherence to 15,000 km or annual oil change intervals to prevent VVT solenoid clogging and timing chain tensioner wear. Renault RN0700 (5W-40) oil is critical due to its specific additive package protecting the chain and VVT components. The engine is an interference design; any timing chain failure can cause catastrophic valve damage. Regular inspection of the timing chain tensioner, especially after 100,000 km, is advised per Renault Technical Note MEC 08A.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault Technical Note MEC 08A). ACEA A3/B4 is the minimum acceptable standard.
Emissions: Euro 5 certification applies to all production years (2008-2015) (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under EEC 80/1269 standards. Output figures are consistent across documented variants (Renault Technical Note MEC 08A).

The Renault M4R 714 was used across Renault's Laguna III and Mégane III platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU calibrations for the Scénic III-but no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the front of the cylinder block, near the gearbox flange (Renault Service Manual 77 11 308 987). The 8th digit of the VIN typically corresponds to the engine code 'M4R'. Visually, the engine is identified by its black plastic intake manifold and the '16V' and '2.0' badges on the cam cover. Critical differentiation from the turbocharged M4Rt: The M4R 714 lacks a turbocharger and associated intercooler plumbing. Service parts for the VVT system are specific to the M4R 714 and not interchangeable with earlier F4R engines.
The M4R 714's primary reliability risk is variable valve timing (VVT) system malfunction, with elevated incidence in vehicles with irregular oil changes. Renault internal data indicates VVT-related faults are a common cause for diagnostic intervention, while owner reports frequently cite timing chain tensioner noise. Extended oil change intervals and use of incorrect oil viscosity make VVT solenoid replacement and tensioner inspection critical.
Analysis derived from Renault technical bulletins (2008-2015) and owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
