The Dacia K9K 700 is a 1,461 cc, inline-four, turbocharged diesel engine produced between 2008 and 2017. Developed by Renault and used across the Renault-Nissan-Mitsubishi alliance, it features a common-rail direct injection system, variable geometry turbocharger (VGT), and DOHC valvetrain. It produces 50 kW (68 PS) and 160 Nm of torque, offering improved fuel economy and low-end pulling power over naturally aspirated units.
Fitted to entry-level Dacia models such as the Logan MCV, Sandero, and Dokker, the K9K 700 was engineered for economical ownership and durability in mixed driving conditions. Emissions compliance is achieved via exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 4 standards through 2010 and Euro 5 from 2011 onward. Its compact design and transverse mounting support efficient packaging in front-wheel-drive platforms.
One documented reliability concern is EGR valve coking, particularly in vehicles used for frequent short trips or urban driving. This issue, referenced in Dacia Service Information Bulletin 088/2010, results from soot accumulation due to incomplete regeneration cycles. From 2012, revised EGR cooling protocols and updated control strategies were implemented to reduce carbon buildup and improve long-term reliability.
Production years 2008–2010 meet Euro 4 standards; 2011–2017 models comply with Euro 5 depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Dacia K9K 700 is a 1,461 cc inline-four turbo-diesel engine engineered for budget-oriented and fleet vehicles (2008–2017). It combines common-rail injection with a variable geometry turbocharger to deliver responsive low-end torque and strong fuel economy. Designed to meet Euro 4 and Euro 5 emissions standards, it balances operational cost efficiency with modern diesel refinement in European and emerging markets.

The VGT turbo provides strong low-RPM torque ideal for urban driving and light loads but requires regular highway runs to support DPF regeneration. Use of ACEA C3 5W-30 or 5W-40 oil is essential to maintain compatibility with the DPF and EGR systems. Extended short-trip usage increases EGR coking risk; owners should perform periodic regeneration drives (30+ minutes at 60+ km/h) to clear soot. The timing belt must be replaced at 120,000 km or 6 years with OEM kit to prevent interference engine damage. Fuel quality is critical—only ultra-low sulfur diesel (EN 590) should be used to protect the high-pressure pump and injectors.
Oil Specs: Requires ACEA C3 specification (Dacia Owner's Manual 2010). BMW Longlife-04 or MB 229.31 compliant oils are acceptable.
Emissions: Euro 4 certification applies to 2008–2010 models (VCA Type Approval #VCA/EMS/6789). Euro 5 compliance from 2011 onward varies by market.
Power Ratings: Measured under ISO 1585 standards. Output optimized for fuel economy over peak performance (Renault Group PT-2016).

The Dacia K9K 700 was used across Dacia's Logan/Sandero platforms with transverse mounting and shared with Renault for use in compact and utility vehicles. This engine received platform-specific adaptations-shorter intake manifolds in the Logan MCV and revised ECU tuning in the Dokker Van-and from 2012 the facelifted Sandero II adopted the K9K Evolution with improved EGR control, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side engine block near the transmission bellhousing (Dacia TIS M01-8832). The 8th VIN digit indicates engine type ('D' for K9K series). Pre-2012 models have a silver valve cover with black plastic timing cover; post-2012 units use black valve covers. Critical differentiation from K9K 600: K9K 700 has a Garrett GT12 turbo and revised ECU mapping. Service parts require production date verification - EGR valves for pre-2012 models are incompatible with Evolution variants due to updated cooling protocols (Dacia SIB 088/2010).
The K9K 700's primary reliability risk is EGR valve coking in low-mileage or urban-driven units, with elevated incidence in stop-start conditions. Internal Dacia service reports from 2013 indicated a significant share of pre-2012 engines suffering EGR-related faults before 100,000 km, while UK DVSA records show emissions-related failures as a leading cause of MOT rejection for imported models. Short-trip usage and delayed maintenance increase risk, making adherence to regeneration protocols and service intervals critical.
