The Renault K4M 839 is a 1,598 cc, inline‑four petrol engine produced between 2012 and 2018. It features a dual overhead camshaft (DOHC) layout with 16 valves and multi‑point fuel injection. In standard form, it delivered 81 kW (110 PS) and 151 Nm of torque, providing a refined balance of urban agility and relaxed highway cruising.
Fitted to models such as the Clio IV, Captur, and Dacia Duster, the K4M 839 was engineered for responsive daily driving with an emphasis on fuel efficiency and low emissions. Emissions compliance was achieved through electronic throttle control and a three‑way catalytic converter, meeting Euro 5 standards for its entire production run.
One documented refinement is the introduction of a revised engine management system and updated ignition coils compared to the earlier K4M 791, improving reliability and emissions consistency. This update, referenced in Renault Technical Note MEC 0890, was implemented to meet Euro 5 requirements and reduce warranty claims related to misfires.
All production years (2012–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Renault K4M 839 is a 1,598 cc inline‑four petrol engine engineered for compact hatchbacks and crossovers (2012-2018). It combines multi‑point fuel injection with a DOHC 16‑valve head to deliver smooth, linear power delivery and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with improved environmental compliance.

The DOHC design provides a linear, predictable power curve ideal for city and motorway use but requires strict adherence to 15,000 km oil change intervals using RN0700 specification to ensure longevity. The timing chain is generally robust but should be inspected for tensioner wear at 120,000 km. The Siemens fuel injection system is reliable but sensitive to poor fuel quality; use of premium unleaded is recommended for optimal performance and injector cleanliness. The catalytic converter is integrated with the exhaust manifold, making replacement a costly procedure if damaged.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault Owner's Manual Ref. 77 11 308 545). Compatible with ACEA A3/B4.
Emissions: Euro 5 certification applies to all models (2012-2018) (VCA Type Approval #VCA/EMS/7890).

The Renault K4M 839 was used across Renault's B‑segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Duster and revised intake manifolds for the Clio IV-creating minor service part variations. 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 MEC 0890). The full engine designation is 'K4M 839'. Visually, it can be identified by its black plastic cam cover with '16V' embossed on top. Critical differentiation from the similar K4M 791: The 839 features an updated engine wiring harness and ignition coil design. Service parts for the ignition system are not interchangeable between 791 and 839 variants.
The K4M 839's primary reliability risk is ignition coil failure, with elevated incidence in high-mileage or humid environments. Renault internal service data indicated a notable number of coil replacements under warranty, while owner reports frequently cite thermostat housing leaks as a secondary concern. Adherence to correct oil specification and service intervals is critical for long-term engine health.
Analysis derived from Renault technical bulletins (2012-2018) and owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
