All about the Dacia Logan 1All about the 1.5 dCi (K9K) engine
The 1.5 dCi (K9K) engine was fitted to the Dacia Logan 1 (2004–2012). In the EU that is 39.6 % of all new cars of this generation.
Versions: 1.5, 1.5 88 hp, 1.5 75 hp, 1.5 86 hp.
The most expensive known risk is injector wear (high return flow, rough running): it usually appears at 150,000–250,000 km and costs €400–1,400 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: Knocking from the bottom end when warm, oil pressure warning; if ignored the crankshaft is damaged and the engine fails
Fix: On early engines change oil every 10,000-15,000 km with the correct spec; at the first knock stop driving and replace the con-rod bearings (preventive bearing change is common on high-mileage early cars)
Signs: Hard starting or no start, misfire and smoke, rail pressure fault codes, several injectors failing at once
Fix: Check the fuel filter and the pump for metal particles; replace the pump and the contaminated injectors, rail and lines and flush the tank, otherwise new parts fail again
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: 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: Belt snaps or jumps well before the 160,000 km interval; the engine stops and valves are bent
Fix: On these cars ask a Renault dealer by VIN whether the service bulletin on the high-pressure pump / belt drive was done, and do not run the belt to 160,000 km; change it at 120,000 km or 6 years at the latest
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: Rattle at idle, vibration pulling away
Fix: Replace with clutch
Typical routine maintenance cost for 100,000 km: €3,100–6,950. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
