The Dacia K9K 884 is a 1,461 cc, inline-four diesel engine produced between 2013 and 2018. It belongs to the Renault-Nissan Alliance's K9K engine family, designed for durability and fuel efficiency in entry-level vehicles. Equipped with a common-rail direct injection system and a variable geometry turbocharger (VGT), it produces 66 kW (90 PS) at 4,000 rpm and 200 Nm of torque at 1,750 rpm. This configuration ensures strong low-end pull ideal for urban driving and light load conditions.
Fitted to core models such as the Dacia Sandero Stepway and Logan MCV, the K9K 884 was engineered for economical operation and long service intervals. Its design supports Euro 5 emissions compliance through a diesel particulate filter (DPF), cooled exhaust gas recirculation (EGR), and selective catalytic reduction (SCR) with AdBlue injection in later variants. The engine's architecture prioritises reliability and drivability, with a power output tuned for responsive city performance.
One documented concern is EGR cooler leakage observed in high-mileage units, particularly in vehicles used for frequent short trips. This issue, addressed in Renault Group Service Bulletin TSB 09-052, arises from thermal cycling stress and carbon buildup restricting coolant flow. From 2015, revised EGR cooler core materials and updated coolant maintenance intervals were implemented to improve longevity.
Production years 2013–2015 meet Euro 5 standards; 2016–2018 models with SCR system maintain Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5680).
The Dacia K9K 884 is a 1,461 cc inline-four turbo-diesel engine engineered for entry-level hatchbacks and MPVs (2013–2018). It combines common-rail direct injection with a variable geometry turbocharger to deliver strong low-RPM torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday drivability with emissions control and mechanical simplicity.

The VGT turbo provides strong low-RPM torque ideal for city driving but requires regular highway runs to maintain DPF health. SAE 5W-30 oil meeting ACEA B4 or C3 is essential for turbo and injector protection, particularly in stop-start traffic. The timing belt must be replaced every 120,000 km or 6 years—failure risks interference damage. Fuel quality is critical; non-EN 590 diesel can cause high-pressure pump and injector failure. Post-2015 models benefit from improved EGR cooler materials; pre-2015 units should follow extended coolant change intervals per Renault SIB 09 052. The SCR system requires AdBlue top-ups every 10,000 km in real-world use to prevent limp mode.
Oil Specs: Requires SAE 5W-30 meeting ACEA B4 or C3 (Renault SIB 09 052). Compatible with VW 505 00/505 01 specifications.
Emissions: Euro 5 certification applies to all K9K 884 models (VCA Type Approval #VCA/EMS/5680). SCR-equipped variants require AdBlue for compliance.
Power Ratings: Measured under ECE R85 standards. Output consistent across all markets; no performance variants.

The Dacia K9K 884 was used across Dacia's Logan MCV/Sandero Stepway platforms with transverse mounting and shared architecture with Renault and Nissan for global applications. This engine received platform-specific adaptations-shortened intake manifolds in the Sandero Stepway and revised exhaust routing in the Logan MCV-and from 2016 the facelifted Logan II MCV introduced SCR-based emissions control, creating partial interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the left-side engine block near the transmission bellhousing (Renault TIS B17422). The 8th VIN digit indicates engine type ('K' for K9K series). Pre-2016 models have silver valve covers with ribbed intake manifolds; post-2016 units use black valve covers. Critical differentiation from K9K 658: K9K 884 produces 90 PS, while K9K 658 delivers 68 PS. Service parts require production date verification - timing belts for pre-2016 models are incompatible with post-2016 SCR-equipped variants due to ECU and sensor integration (Renault SIB 09 052).
The K9K 884's primary reliability risk is EGR cooler leakage on high-mileage units, with elevated incidence in urban stop-start use. Internal Renault quality reports from 2016 noted increased warranty claims for EGR cooler replacement in European city fleets, while UK DVSA data shows SCR system faults as a leading cause of emissions-related MOT failures in imported units. Short trip cycles and poor coolant maintenance exacerbate deposits, making maintenance adherence critical.
