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 enginee…
Production years 2008–2010 meet Euro 4 standards; 2011–2015 models meet Euro 5 standards .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M4R 700 is generally a robust and reliable engine when maintained correctly. Its main vulnerabilities are the VVT system and timing chain tensioner, which are highly dependent on using the correct oil and adhering to service intervals. With proper care, these engines can easily exceed 200,000 km without major issues.
The most frequent issues are VVT solenoid or phaser failures, timing chain tensioner rattle, IMRC motor faults, and valve cover gasket leaks. These are well-documented in Renault's technical service bulletins and are often preventable with diligent maintenance and the use of specified oils.
The M4R 700 engine was primarily used in the Renault Laguna III (2008-2015), Mégane III (2008-2015), Scénic III (2009-2015), and Kangoo II (2008-2013). It was offered in various power outputs from 140 PS to 170 PS across these model lines.
Aftermarket ECU tuning is common on the M4R-700 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Real-world fuel economy varies by model and driving style. Expect approximately 8.5–9.5 L/100km (30–33 mpg UK) in mixed driving for a Laguna or Mégane. Highway cruising can yield 6.5–7.5 L/100km (38–43 mpg UK), while city driving may consume 10.5–12.0 L/100km (24–27 mpg UK).
Yes. The M4R 700 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, resulting in severe internal engine damage requiring a costly rebuild or replacement.
Renault specifies RN0700 or RN0710 fully synthetic oil, typically in 5W-40 viscosity. Using oil that meets these exact specifications is crucial for the longevity of the VVT system and timing chain. The service interval should not exceed 15,000 km or 12 months.
