The Renault K9K 820 is a 1,461 cc, inline‑four turbo‑diesel engine produced between 2012 and 2018. It features an evolution of the common rail direct injection system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). Delivering 66 kW (90 PS) and 220 Nm of torque, it represents a refinement of the K9K series, with “Euro 6 readiness” enabling smoother compliance with stricter emissions norms.
Fitted primarily to the Clio IV, Captur, and later Kangoo models, the K9K 820 was engineered for enhanced urban efficiency and reduced NVH. Drivers benefit from a more linear power delivery compared to earlier fixed-geometry variants, making it suitable for both city commutes and highway cruising. Emissions compliance was achieved through a cooled exhaust gas recirculation (EGR) system and a diesel particulate filter (DPF), meeting Euro 5 standards with provisions for Euro 6.
A documented reliability focus for this variant involves the high-pressure fuel pump and associated injectors, as noted in Renault Technical Note CLI‑12‑008. This is often linked to fuel quality and extended service intervals leading to premature wear. From mid-2015, Renault implemented revised pump internals and updated ECU calibrations to improve durability.
All production years (2012–2018) meet Euro 5 standards; select 2016–2018 models are Euro 6 compliant (VCA UK Type Approval #VCA/EMS/9101).
The Renault K9K 820 is a 1,461 cc inline‑four turbo‑diesel engineered for B-segment hatchbacks and crossovers (2012-2018). It combines updated Denso HP4 common‑rail injection with a variable‑geometry turbocharger to deliver refined low‑end torque and improved emissions control. Designed to meet Euro 5 standards with Euro 6 readiness, it balances urban agility with regulatory compliance.

The VGT provides a broader, flatter torque curve than fixed-geometry predecessors, enhancing drivability. Renault RN0710 (5W-30) oil is mandatory for its low-SAPS properties, crucial for DPF longevity. The high-pressure fuel pump is sensitive to fuel contamination; using ultra-low sulfur diesel (EN 590) is essential. Extended oil change intervals can accelerate chain tensioner wear. Post-2015 models feature a revised fuel pump design; pre-2015 units may benefit from the updated part per Renault Technical Note CLI-12-008.
Oil Specs: Requires Renault RN0710 specification (Renault Service Manual 1461D Rev.2). RN0700 is not suitable for DPF-equipped vehicles.
Emissions: Euro 5 certification is standard for 2012-2015 models (VCA Type Approval #VCA/EMS/9101). Euro 6 compliance applies to specific 2016-2018 variants.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Renault EPC Ref. K9K-820-01).

The Renault K9K 820 was used across Renault's B platform with transverse mounting. This engine received platform-specific adaptations-revised engine mounts in the Captur for NVH refinement and a specific air intake design in the Clio IV-and from mid-2015 models adopted the updated HP4 fuel pump, creating minor parts differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the gearbox flange (Renault TIS A12346). The 8th VIN digit typically corresponds to the engine code (e.g., '8' for K9K 820). All K9K 820 engines feature a metallic inlet pipe and a variable geometry turbo. Critical differentiation: Pre-mid-2015 models use an earlier design high-pressure fuel pump (Denso 294000-0790); post-mid-2015 units use a revised pump (Denso 294000-1120) with improved durability per Renault Technical Note CLI-12-008.
The K9K 820's primary reliability focus is high-pressure fuel pump failure, with elevated incidence in vehicles subjected to poor fuel quality or infrequent highway use. Renault internal service data indicated a notable rate of pump-related faults in pre-2015 builds, while UK DVSA MOT data shows DPF issues remain a leading cause of failure for diesel vehicles of this era. Fuel quality and driving patterns make proactive maintenance critical.
