The Renault K4M 762 is a 1,598 cc, inline‑four petrol engine produced between 2008 and 2016. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection. This naturally aspirated unit delivered 81 kW (110 PS) and 151 Nm of torque, offering a balance of responsiveness and everyday drivability for its vehicle class.
Fitted primarily to the Mégane III, Scénic III, and Duster platforms, the K4M 762 was engineered for dependable urban and hi…
Production years 2008–2010 meet Euro 4 standards; 2011–2016 models meet Euro 5 standards .
The Renault K4M 762 is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact family vehicles (2008-2016). It combines multi‑point fuel injection with a DOHC 16‑valve head and variable valve timing to deliver smooth, linear power delivery. Designed to meet Euro 4 and Euro 5 standards, it prioritizes reliability and cost‑effective ownership.

The Renault K4M 762 was used across Renault's Mégane III and Scénic III platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU calibrations for different body weights-and a mid-cycle update for Euro 5 compliance, which included revised catalytic converter and engine management software, creating minor interchange limits. 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
Generally, the K4M 762 is a robust and reliable engine. Its main known issue is the VVT solenoid, which Renault addressed with updated parts. With strict adherence to oil changes using RN0700 5W-40 and addressing common ancillary issues like coils and thermostats, these engines can easily surpass 200,000 km without major problems.
The most documented issue is VVT solenoid failure. Other frequent problems include ignition coil failures, coolant leaks from the plastic thermostat housing, and wear of the timing chain tensioner. These are covered in Renault service documentation and are generally straightforward to repair.
The K4M 762 was used in the Renault Mégane III (2008-2016), Scénic III (2009-2016), and the Dacia Duster (2010-2016), all badged as the '1.6 16V'. It was a common engine for Renault's compact and family vehicle lineup during this period.
Minor gains are possible. An ECU remap might yield 5-10 kW extra by optimizing ignition and fuel maps. Significant power increases are limited by the naturally aspirated design and would require forced induction, which is complex and costly. Most owners focus on maintenance for longevity rather than tuning.
Real-world fuel economy is reasonable. Expect around 8.0-9.0 L/100km (31-35 mpg UK) in mixed urban driving and 6.0-7.0 L/100km (40-47 mpg UK) on the highway in a Mégane III. Actual figures depend heavily on driving style, vehicle condition, and whether it's paired with a manual or automatic transmission.
Yes. The K4M 762 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Renault mandates oil meeting the RN0700 specification, typically a 5W-40 synthetic or semi-synthetic. Using this specific oil is crucial, especially for protecting the VVT system and camshafts. Change intervals should not exceed 15,000 km or 12 months, whichever comes first.
