All production years (2013–2019) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Renault K4M 862 is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact SUVs and crossovers (2013-2019). It combines multi-point fuel injection with DOHC 16-valve architecture to deliver predictable, linear power and robust everyday drivability. Designed to meet Euro 5 standards, it prioritizes reliability and serviceability in varied conditions.

The Renault K4M 862 was used almost exclusively in Renault and Dacia's HS platform compact SUVs with transverse mounting. This engine features platform-specific adaptations-reinforced engine mounts and a specific exhaust manifold-for the Duster. All adaptations are documented in OEM technical bulletins.
The K4M 862's primary reliability consideration is its interference-design timing belt, where failure leads to catastrophic engine damage. Renault internal service data indicates that adherence to the 120,000 km replacement schedule is critical, while owner reports frequently cite ignition coil failures as a common electrical fault. Extended oil change intervals can contribute to sludge buildup, making scheduled maintenance non-negotiable for longevity in demanding conditions.
Analysis derived from Renault technical bulletins (2013-2019) and UK DVSA failure statistics (2018-2023). 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 862 is generally reliable with diligent maintenance. Its main vulnerability is the timing belt; failure to replace it causes major engine damage. Ignition coils are a common wear item. Regular oil changes and timely belt service are crucial for achieving high mileage, especially given its use in the rugged Duster platform.
The most frequent issues are timing belt/tensioner failure if neglected, ignition coil pack failures causing misfires, electronic throttle body faults leading to idle issues, and coolant temperature sensor malfunctions. These are well-documented in Renault service information.
This 1.6L petrol engine was fitted almost exclusively to the Dacia Duster and Renault Duster from 2013 to 2019. It was typically badged as '1.6 16V' across various trim levels like Ambiance, Laureate, Expression, and Dynamique.
Modest gains are possible. An ECU remap can typically yield an extra 5-8 kW (7-10 PS) and slightly improved torque. Bolt-on modifications offer marginal improvements. Significant power increases are impractical due to the naturally aspirated design and the engine's focus on durability over performance.
Real-world fuel economy is reasonable for an SUV. In a Duster, expect combined figures of approximately 7.5–8.5 L/100km (33–38 mpg UK). Consumption will be higher in city driving (9-10 L/100km) and lower on highways (6.0-6.8 L/100km), depending on terrain and driving style.
Yes. The K4M 862 is an interference engine. If the timing belt breaks or jumps teeth, the pistons will collide with the open valves, causing severe internal damage that usually necessitates a complete engine rebuild or replacement.
Renault specifies oil meeting the RN0700 standard, typically a 5W-40 synthetic or semi-synthetic. Using the correct specification is vital for engine protection, especially under the varied conditions the Duster is designed for. Change intervals should not exceed 15,000 km or 12 months, whichever comes first.
