The Dacia K9K 858 is a 1,461 cc, inline — four, turbo — diesel engine produced between 2013 and 2020. It belongs to the Renault — Nissan Alliance's K9K engine family, refined for improved efficiency and emissions compliance. Featuring common — rail direct injection, a variable geometry turbocharger (VGT), and DOHC valvetrain, it produces 81 kW (110 PS) and 240 Nm of torque, offering stronger performance than lower — output K9K variants while maintaining fuel economy.

All K9K 858 units meet Euro 5 emissions standards . SCR system requires AdBlue refills every 12,000–15,000 km.
The Dacia K9K 858 is a 1,461 cc inline-four turbo-diesel engineered for compact and subcompact models (2013–2020). It combines common-rail direct injection with a single variable-geometry turbocharger to deliver strong mid-range torque and responsive performance. Designed to meet Euro 5 standards with SCR-assisted aftertreatment, it balances power and efficiency in higher-trim applications.

The Dacia K9K 858 was used across Dacia's Sandero, Logan, and Duster platforms with transverse mounting. This engine received platform-specific adaptations-shortened intake manifolds in the Sandero and revised engine mounts in the Duster-and from 2013 the facelifted Logan MCV adopted updated ECU tuning for improved cold-start performance, creating minor calibration 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 858 is generally robust when maintained properly. Key concerns include turbo actuator wear and EGR clogging, especially in urban environments. Adhering to oil change intervals (15,000–20,000 km) and replacing the timing belt every 120,000 km or 6 years is critical. Engines with full service history and clean DPFs can exceed 250,000 km reliably.
The most frequent issues are turbocharger actuator failure, EGR and intake carbon buildup, timing belt degradation, and DPF clogging. These are documented in Renault service bulletins and are often linked to extended oil intervals or frequent short trips. Regular maintenance significantly reduces failure rates.
The K9K 858 1.5 dCi 110 engine was used in the second-generation Sandero (2013–2020), second-generation Logan MCV (2013–2020), and facelifted first-generation Duster (2013–2020). All models meet Euro 5 standards. It is not used in the Jogger or third-generation Sandero.
Yes, the K9K 858 can be tuned via ECU remap, typically gaining +20–30 kW. However, stock turbo and fuel system components limit safe gains. Over-tuning increases risk of turbo failure, EGR stress, and DPF overload. Supporting modifications like upgraded intercooler and exhaust are recommended for higher power levels.
Excellent for its class. In a Duster 1.5 dCi 110, combined consumption is ~4.7 L/100km (60 mpg UK). City driving averages ~5.8 L/100km (49 mpg), while highway runs can achieve ~4.2 L/100km (67 mpg). Real-world economy typically ranges 45–58 mpg UK depending on driving style and vehicle load.
Yes. The K9K 858 is an interference engine. If the timing belt fails, the pistons can strike the open valves, causing severe internal damage. This makes strict adherence to the 120,000 km or 6-year replacement interval essential. Any signs of belt wear should be addressed immediately.
The engine requires 5W-30 oil meeting Renault RN0700 or ACEA C3 specifications. This low-SAPS oil is critical for protecting the DPF, SCR, and EGR system. Oil should be changed every 15,000–20,000 km or annually to maintain engine longevity and emissions compliance.
