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 enhanced performance over earlier K9K variants while maintaining excellent fuel economy.
Fitted to core Dacia models including the Sandero II, Logan II, and Dokker, the K9K 894 was designed to meet Euro 5b and later Euro 6d emissions standards through a combination of exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective catalytic reduction (SCR) in post-2020 models. It balances responsive low-end torque with quiet operation and is targeted at urban and mixed-use driving patterns.
One documented reliability concern is EGR valve coking, particularly in vehicles used for frequent short trips or low-load operation. This issue, referenced in Renault Service Information Bulletin 2048-T, results in restricted airflow and increased soot loading on the DPF. Renault introduced a revised EGR cooler design in 2017 with improved coolant flow and reduced carbon accumulation in later production units.
Production years 2013–2019 meet Euro 5b standards; 2020–2023 models comply with Euro 6d (VCA UK Type Approval #VCA/EMS/5680).
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 VGT turbo provides strong low-RPM torque ideal for city driving but requires adherence to 15,000 km oil change intervals to prevent EGR and turbo fouling. SAE 5W-30 oil meeting ACEA C3 specification is critical due to its low-SAPS formulation protecting the DPF and EGR system. Extended short-trip driving inhibits passive DPF regeneration, increasing risk of clogging. The common-rail system demands ultra-low-sulfur diesel (EN 590) to prevent injector wear. Post-2017 models feature improved EGR cooler design; pre-2017 units should be inspected for carbon buildup during service. Cold-start idling should be minimized to reduce soot accumulation in the intake tract.
Oil Specs: Requires ACEA C3 specification (Renault SIB 2048-T). Compatible with low-SAPS synthetic oils to protect DPF.
Emissions: Euro 5b certification applies to pre-2020 models only (VCA Type Approval #VCA/EMS/5680). Euro 6d applies to 2020–2023 models with SCR integration.
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (Renault Group PT-2018).

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.
Locate the engine code stamped vertically on the right side of the cylinder block, near the transmission bellhousing (Renault TIS B13782). The 8th VIN digit indicates engine type ('K' for K9K series). Pre-2020 models have a silver valve cover with a rubber gasket; post-2020 units use a black valve cover with integrated breather. Critical differentiation from K9K 704: K9K 894 features revised ECU calibration for higher torque and updated emissions control; visually identical but requires different ECU and injector coding. Service parts require model-year verification—timing belts for pre-2017 engines are not compatible with post-2017 Euro 6 variants due to tensioner redesign (Renault SIB 2048-T).
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.
