All about the Dacia Logan 2All about the 1.5 dCi (K9K) engine
The 1.5 dCi (K9K) engine was fitted to the Dacia Logan 2 (2012–2020). In the EU that is 29.6 % of all new cars of this generation.
Versions: 1.5 90 hp, 1.5 75 hp, 1.5, 1.5 95 hp.
The most expensive known risk is DPF clogging, failed regenerations: it usually appears at 80,000–200,000 km and costs €150–1,500 to fix.
✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Hard hot starting, rough idle, black smoke, power loss, return flow out of tolerance on the test
Fix: Return-flow (leak-off) test and live-data correction check; recondition or replace the faulty injectors with new copper seals
Signs: Jerky idle, black smoke, power loss, EGR fault codes (e.g. P0401); worse with short town trips
Fix: Check EGR position in live data; clean the valve and intake, replace the valve if it sticks or its motor fails
Signs: DPF warning, frequent or interrupted regenerations, limp mode; mostly cars used for short trips
Fix: Check the differential pressure sensor and EGR first, then forced regeneration, cleaning or replacement; use low-ash RN0720 oil
Signs: Whistling, blue smoke, oil use, loss of power or limp mode (P0299 underboost)
Fix: First check boost hoses and clamps and the intercooler pipes; if the turbo has play, replace it and clean or replace the oil feed line and check oil pressure
Signs: Oil level drops quickly between services, oil can reach the intake; risk of running low on oil
Fix: Check the oil level often; ask a Renault/Dacia dealer for the free ECU reprogramming campaign and an oil-consumption test
Signs: Surface rust underneath, brake lines
Fix: Treat underbody; replace pipes
Signs: Knocking
Fix: Replace parts
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Won't select a gear, 'gearbox fault', jerky shifts
Fix: Repair or replace the actuator; clutch re-learn
Signs: Slipping, harsh engagement
Fix: Replace clutch + re-learn
Typical routine maintenance cost for 100,000 km: €3,100–7,250. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
