When buying a used Dacia Logan 1.5 d 2015 (2nd generation), the most frequently mentioned issues are: sensors, solenoid valves and limp mode. DPF clogging is also commonly reported.
Engine varies by trim; verify the engine code on the listing.
Listed from most frequently reported, each with its source.
Sensors (turbo pressure/MAP, lambda probe, temperature sensors) and solenoid valves connected to the engine management system can fail or give incorrect readings, causing the engine warning light to come on and the vehicle to enter a power-limited limp mode.
Engine Bay
On the 1.5 dCi, the DPF tends to clog, especially with city driving and many short trips.
Exhaust Emissions
The EGR valve on the K9K 1.5 dCi can accumulate soot and deposits, causing rough running, unstable idle, black smoke and the engine warning light to come on. Cleaning may provide a temporary fix, but heavily caked or faulty valves need replacement.
Exhaust Emissions
Injectors on 1.5 dCi engines can fail or lose efficiency, leading to warning lights, vibration, power loss and increased fuel consumption.
Fuel System
The turbocharger and its hoses (pipes, bellows, wastegate) are weak points: hose rupture, turbo wear or actuator failure cause power loss, abnormal whistling, smoke and error messages.
