The Renault K9K 830 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2012 and 2018. It features a cast iron block, aluminium cylinder head, common rail direct injection, and a variable‑geometry turbocharger. In standard form it delivered 81 kW (110 PS), with torque figures of 240 Nm, providing enhanced low‑rpm pull for improved drivability.
Fitted to models such as the Clio IV, Captur, and Dacia Sandero Stepway, the K9K 830 was engineered for compact car e…
All production years (2012–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6789).
The Renault K9K 830 is a 1,461 cc inline‑three turbo‑diesel engineered for B-segment platforms (2012-2018). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver responsive mid‑range torque and improved fuel efficiency. Designed to meet Euro 5 standards, it offers a balance of urban agility and highway capability.

The Renault K9K 830 was used across Renault's B-segment platforms with transverse mounting and licensed to Dacia. This engine received platform-specific adaptations-reinforced mounts in the Captur and revised cooling in the Clio IV-and from 2015 the facelifted models adopted a revised turbo actuator, creating minor parts interchange limits. All adaptations are documented in OEM technical bulletins.
The K9K 830's primary reliability risk is turbocharger actuator failure, with elevated incidence in high-mileage vehicles. Renault internal service data indicates a high frequency of actuator-related repairs on vehicles exceeding 100,000 km, while UK DVSA records show a correlation between boost pressure faults and neglected services for this engine. Infrequent highway driving and missed services increase thermal stress, making adherence to the maintenance schedule critical.
Analysis derived from Renault technical bulletins (2012-2018) and UK DVSA failure statistics (2015-2023). 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 K9K 830 is generally robust, but its long-term reliability depends heavily on maintenance. Vehicles serviced regularly with the correct oil and driven on longer journeys can exceed 150,000 km. The main threats are turbo actuator failure and EGR/DPF issues from short trips and neglected services.
The most frequent issues are turbocharger actuator failure, DPF regeneration problems, EGR valve sticking, and timing belt wear. These are well-documented in Renault service bulletins and are often linked to maintenance neglect and urban driving patterns.
This 1.5 dCi 110 engine was used in the Renault Clio IV (2012-2018), Captur (2013-2018), and was licensed to Dacia for the Sandero Stepway (2013-2018) and to Nissan for the Micra K13 (2013-2017).
Yes, it is commonly tuned. A Stage 1 ECU remap can safely increase power to 125-135 PS and torque to 260-280 Nm. The bottom end is strong, but supporting modifications like an upgraded intercooler are recommended for higher power levels to manage increased thermal load.
Very good. In a Clio IV, expect 4.2 L/100km (67 mpg UK) on a combined cycle. Real-world figures typically range from 55-65 mpg UK, depending on the model, driving style, and whether EGR/DPF systems are functioning correctly.
Yes. The K9K 830 is an interference engine. If the timing belt snaps, the pistons will collide with the open valves, causing catastrophic engine damage. Replacing the belt at the recommended interval (typically 120,000 km or 5 years) is non-negotiable.
Renault specifies a 5W-30 synthetic oil meeting the RN0710 (or newer RN17) standard. This low-SAPS oil is critical for protecting the DPF and EGR system. Using the wrong oil will lead to premature DPF clogging and potential engine damage.
