RENAULT K4M-761 engine (2008–2016) – Specs, Problems & Compatibility Database

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 enhanced drivability across urban and highway conditions. Emissions compliance was achieved through optimized combustion and catalytic conversion, meeting Euro 4 and Euro 5 standards depending on the model year and market.

A key update from the K4M 740 was the introduction of an electronic throttle body (drive-by-wire), replacing the cable-operated system. This change, documented in Renault Technical Information System Doc. K4M-003, improved throttle response mapping and enabled better integration with traction and stability control systems.

Compliance Note:

Production years 2008–2010 meet Euro 4 standards; 2011–2016 models meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6789).

K4M-761 Technical Specifications

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.

Practical Implications

The electronic throttle provides smoother, more precise control but requires periodic ECU adaptation resets after battery disconnection or component replacement. Renault RN0700 (5W-40) oil remains critical for camshaft and chain longevity. The timing chain is designed for the engine's life, but tensioner wear can occur; listen for startup rattles. Compared to the K4M 740, the 761 has no documented camshaft wear issues, indicating a successful metallurgical update.

Data Verification Notes

Oil Specs: Requires Renault RN0700 specification (Renault Owner's Manual). ACEA A3/B4 is the underlying standard.

Emissions: Euro 4/5 certification applies as per model year (VCA Type Approval #VCA/EMS/6789).

Power Ratings: Measured under ECE R85 standards. Output is consistent across specified fuel grades (Renault TIS Doc. K4M-003).

K4M-761 Compatible Models

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.

Identification Guidance

Locate the engine code stamped on a flat pad on the front face of the cylinder block, near the gearbox flange (Renault TIS K4M-003). The 8th digit of the VIN typically corresponds to the engine code 'K4M'. Visually, the engine has a black plastic cam cover with '16V' embossed. Differentiation from K4M 740: The K4M 761 uses an electronic throttle body (drive-by-wire) with a visible electrical connector on the throttle body, while the 740 uses a cable. The 761 also features a revised intake manifold design.

Throttle Body Adaptation

Issue:

The electronic throttle body requires periodic adaptation resets via diagnostic tool, especially after battery replacement or cleaning.

Evidence:

Renault TIS Doc. K4M-003

Recommendation:

Perform throttle body adaptation using a Renault-compatible diagnostic scanner (CLIP or equivalent) after any service that interrupts power or involves throttle body work.

Common Reliability Issues - RENAULT K4M-761

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.

Electronic throttle body faults
Symptoms: Erratic idle, hesitation on acceleration, illuminated engine management light, vehicle entering limp-home mode.
Cause: Contamination of the throttle plate or position sensor, or failure of the internal electric motor due to dust ingress or wear.
Fix: Clean the throttle body or replace it with a new OEM unit; perform electronic adaptation procedure using a diagnostic scanner.
Ignition coil failure
Symptoms: Engine misfire (often on one cylinder), rough running, reduced power, engine management light with misfire codes.
Cause: Internal breakdown of the coil's insulation or primary/secondary windings due to heat cycling and age.
Fix: Replace the faulty ignition coil(s) with genuine Renault units; inspect spark plugs for fouling or excessive gap.
Coolant temperature sensor failure
Symptoms: Incorrect temperature gauge reading, poor fuel economy, difficulty starting when cold, engine management light.
Cause: Degradation of the sensor's internal element or its electrical connector due to heat and vibration.
Fix: Replace the coolant temperature sensor with a new OEM part; ensure the connector is clean and secure.
Oil leaks from crankshaft seal
Symptoms: Oil dripping from the bottom of the engine near the crankshaft pulley, oil residue on the underside of the engine.
Cause: Wear or hardening of the front crankshaft seal over time, allowing oil to escape past the rotating crankshaft.
Fix: Replace the front crankshaft seal; this typically requires removing the auxiliary drive belt and crankshaft pulley.
