The Dacia K9K 894 is a 1,461 cc, inline — four, turbocharged diesel engine produced between 2013 and 2023. Developed by Renault, it belongs to the updated K9K dCi family and was engineered for improved emissions compliance and drivability in entry — level vehicles. Featuring a cast — iron block, aluminium head, high — pressure common — rail direct injection (up to 1,600 bar), and variable geometry turbocharger (VGT), it delivers 66 kW (90 PS) with 200 Nm of torque, offering en…
Production years 2013–2019 meet Euro 5b standards; 2020–2023 models comply with Euro 6d .
The Dacia K9K 894 is a 1,461 cc inline-four turbo-diesel engine engineered for compact and utility vehicles (2013–2023). It combines high-pressure common-rail injection with a variable geometry turbocharger to deliver strong low-RPM torque and efficient fuel use. Designed to meet Euro 5b and Euro 6d emissions standards, it balances performance with compliance through advanced aftertreatment systems.

The Dacia K9K 894 was used across Dacia's Sandero II/Logan II platforms with longitudinal mounting and shared architecture with Renault models. This engine received platform-specific adaptations-reinforced mounts in the Logan II and revised exhaust routing in the Dokker-and from 2020 the facelifted Sandero Stepway adopted Euro 6d-compliant calibration with SCR integration, creating interchange limits. Partnerships allowed Renault to use the same engine in the Clio V and Kangoo III in select markets. 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.
The K9K 894's primary reliability risk is EGR valve coking on pre-2017 units, with elevated incidence in urban driving cycles. Internal Renault quality reports from 2016 indicated a notable share of engines requiring EGR service before 120,000 km, while VCA field data links a significant portion of emissions-related failures to DPF saturation in short-trip vehicles. Infrequent regeneration and poor fuel quality increase clogging risk, making driving pattern and fuel adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K9K 894 is mechanically robust and fuel-efficient when maintained. Pre-2017 engines are prone to EGR coking if used for frequent short trips. Post-2017 revisions improved EGR cooler design. Timing belt replacement at 120,000 km is critical. With proper oil changes and driving patterns that allow DPF regeneration, these engines regularly exceed 250,000 km.
Key issues include EGR valve coking (especially pre-2017), DPF saturation due to short trips, timing belt failure if overdue, and carbon buildup in the intake. These are documented in Renault service bulletins. Oil leaks from the valve cover gasket are also common on high-mileage units.
The K9K 894 was used in the Dacia Sandero II (2013–2023), Logan II (2013–2023), and Dokker (2013–2023). It was also used by Renault in the Clio V and Kangoo III. All variants are 1.5L dCi producing 90 PS. Euro 5b and Euro 6d versions differ in ECU and aftertreatment hardware.
Aftermarket ECU tuning is common on the K9K894 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.
In a Sandero II or Logan II, fuel economy averages 4.3–5.0 L/100km (65–56 mpg UK) in mixed driving. Highway efficiency improves to ~4.0 L/100km (70 mpg UK). Real-world figures depend on load and terrain, but it remains one of the most economical diesel engines in its class.
Yes. The K9K 894 is an interference engine. If the timing belt breaks or jumps, the pistons can strike the open valves, causing severe internal damage. Adhering to the 120,000 km belt replacement interval is essential to prevent costly repairs.
Renault specifies SAE 5W-30 oil meeting ACEA C3 standards. Low-SAPS synthetic oil is required to protect the DPF and EGR system. Change intervals should not exceed 15,000 km or 12 months. Proper oil choice reduces coking and maintains aftertreatment longevity.
