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 Kan…
All production years (2012–2018) meet Euro 5 standards; select 2016–2018 models are Euro 6 compliant .
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 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.
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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 820 is generally reliable with its chain-driven design, but its main vulnerability is the high-pressure fuel pump, especially in pre-2015 models and those using poor-quality fuel. Vehicles from mid-2015 onwards with the revised pump are more robust. Longevity is heavily dependent on using the correct low-SAPS oil (RN0710) and high-quality diesel, along with ensuring the DPF regenerates fully.
The most frequent issues are high-pressure fuel pump failures (pre-2015), DPF blockages from short trips, turbo actuator malfunctions, and glow plug/module faults. These are well-documented in Renault service bulletins and align with common diesel engine failure modes for this generation.
This 1.5L dCi 90 engine was primarily used in the Clio IV (2012-2018), Captur (2013-2018), and Kangoo (2013-2018). It was also found in the Dacia Sandero Stepway (2015-2018) as part of the Renault-Nissan-Dacia alliance, offering a balance of efficiency and performance in B-segment vehicles.
Aftermarket ECU tuning is common on the K9K-820 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Excellent. In a Clio IV 1.5 dCi 90, expect around 4.2 L/100km (67 mpg UK) on a combined cycle. The Captur might return 4.5-4.8 L/100km (63-62 mpg UK). Real-world economy is highly dependent on driving style and ensuring the DPF regenerates efficiently, as blocked DPFs drastically increase consumption.
Yes. The K9K 820 is an interference engine. If the timing chain were to fail (a rare occurrence if serviced correctly), the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper oil maintenance.
Renault mandates RN0710 specification oil, typically 5W-30. This is a low-SAPS (low ash) oil and is essential for vehicles equipped with a DPF to prevent filter clogging. Using the wrong oil will damage the DPF and potentially invalidate warranties. Change intervals should not exceed 20,000 km or 1 year.
