The Renault K4M 761 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 84 kW (114 PS) and 151 Nm of torque, offering refined performance and improved fuel efficiency over its predecessor.
Fitted to models like the Mégane III, Scénic III, and Duster, the K4M 761 was engineered for smooth, quiet operation and enhance…
Production years 2008–2010 meet Euro 4 standards; 2011–2016 models meet Euro 5 standards .
The Renault K4M 761 is a 1,598 cc inline‑four petrol engine engineered for compact and crossover models (2008-2016). It combines DOHC 16-valve architecture with electronic throttle control to deliver smooth, linear power delivery. Designed to meet Euro 4 and Euro 5 standards, it prioritizes refinement and fuel economy for daily driving.

The Renault K4M 761 was used across Renault's Mégane III and Scénic III platforms with transverse mounting. This engine received platform-specific ECU calibrations-minor power mapping differences for the Duster-creating no significant 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.
The K4M 761's primary documented concern is electronic throttle body faults, with higher incidence in vehicles exposed to dusty environments. Renault internal data indicated a measurable rate of throttle body replacement for affected units, while general owner feedback highlights ignition coil failures as a common electrical fault. Inadequate air filter maintenance can accelerate throttle body contamination.
Analysis derived from Renault technical bulletins (2008-2016) and aggregated owner-reported failure data (2012-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The K4M 761 is generally very reliable, addressing the camshaft wear issues of its predecessor. Its main weakness is the electronic throttle body, which can fail or require cleaning. With regular maintenance, including timely air filter changes and using the correct oil, it is a robust and long-lasting engine.
The most common issues are electronic throttle body faults (causing hesitation or limp mode), ignition coil failures, faulty coolant temperature sensors, and front crankshaft oil seal leaks. These are well-documented in Renault service information and common repair guides.
The K4M 761 1.6L 16V petrol engine was primarily used in the Mégane III (2008-2016) and Scénic III (2009-2016). It was also fitted to the first-generation Duster (2012-2016) in many markets. It is not used in Nissan or Dacia models.
Yes, modest gains are possible. An ECU remap can typically yield an extra 8-12 kW by optimizing ignition and fuel maps. Bolt-on modifications like a performance air filter and exhaust can add a few more kW. Significant power increases are limited by the naturally aspirated design.
Fuel economy is good for its class. Expect around 8.2 L/100km in city driving and 5.6 L/100km on the highway in a Mégane III, translating to approximately 34 mpg UK combined. Actual figures vary based on driving style, vehicle condition, and model weight.
Yes. The K4M engine family is an interference design. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage requiring a major rebuild.
Renault specifies oil meeting the RN0700 standard, typically a 5W-40 synthetic or semi-synthetic grade. Using the correct oil is vital for protecting the engine. The service interval is generally 15,000 km or 12 months, whichever comes first.
