The Renault M4R 700 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 power and refinement, with outputs typically ranging from 103 kW (140 PS) to 125 kW (170 PS) and torque between 195-225 Nm.
Fitted to models such as the Laguna III, Mégane III, and Scénic III, the M4R 700 was engineered for smooth, responsive performance in family and executive vehicles. Emissions compliance was achieved through precise electronic fuel injection and VVT, allowing most units to meet Euro 4 and Euro 5 standards depending on the model year and specific calibration.
One documented concern is premature wear of the variable valve timing (VVT) solenoid or phaser, which can trigger check engine lights and affect performance. This issue, referenced in Renault's internal technical notes, is often linked to oil quality or extended service intervals. Later production runs saw minor revisions to the VVT system components.
Production years 2008–2010 meet Euro 4 standards; 2011–2015 models meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault M4R 700 is a 1,997 cc inline‑four naturally aspirated petrol engine engineered for mid‑size family vehicles (2008-2015). It combines DOHC 16-valve architecture with variable valve timing to deliver smooth, linear power delivery and good high-RPM refinement. Designed to meet Euro 4 and Euro 5 standards, it balances everyday drivability with respectable performance.

The naturally aspirated design offers predictable, linear power delivery ideal for relaxed cruising but requires higher RPMs for peak torque. Using the specified Renault RN0700/RN0710 oil is critical to ensure proper lubrication of the VVT system and prevent solenoid/phaser wear. Service intervals should not exceed 15,000 km or 12 months. The timing chain is generally robust but should be inspected for tension and noise at major services. Fuel injectors may require cleaning after 100,000 km to maintain optimal spray patterns and emissions.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Owner's Manual). ACEA A3/B4 is the minimum acceptable standard.
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 varies by model application and ECU calibration (Renault TIS Doc. M4R-005).

The Renault M4R 700 was used across Renault's B/C-platform vehicles with transverse mounting. This engine received platform-specific adaptations-different intake manifolds for the Laguna versus the Mégane-but no major facelift revisions that affect core compatibility. 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-001). The 8th VIN digit typically corresponds to the engine code ('R' for M4R series). Visually, the engine is identifiable by its black plastic camshaft cover with "16V" and "VVT" markings. Critical differentiation from the turbocharged TCe 180: The M4R 700 lacks a turbocharger and associated plumbing. Service parts are generally consistent across model years, but ECU software versions vary significantly between the Laguna, Mégane, and Scénic.
The M4R 700's primary reliability risk is variable valve timing (VVT) system faults, with elevated incidence in vehicles subjected to extended oil change intervals. Renault internal service data indicates a notable correlation between VVT solenoid failures and non-compliant oil usage, while UK DVSA records show timing chain tensioner noise as a common advisory item. Maintaining strict oil quality and service schedules is critical to prevent these issues.
Analysis derived from Renault technical bulletins (2010-2016) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
