Engine Overview
The Dacia Logan 2 is available with 10 engine variants — from 67 to 105 hp. 2 variants had engine changes — the model year is crucial.
Blue dCi variant of the K9K with AdBlue injection (SCR) for Euro 6 — still a very robust engine. In addition to the regular service schedule, top up AdBlue and keep an eye on the SCR catalyst. Injectors and high-pressure pump remain the typical wear points at high mileages.
- !! Injectors worn out from 105,000 km
Delphi injection system (pre-2006) is particularly troublesome — injectors worn out by 60,000 km. Siemens system (from 2006) is significantly better.
Symptoms: Delphi injection system (pre-2006) particularly problematic — injectors worn out by 60,000 km - !! Turbocharger worn from 105,000 km
Turbocharger can develop play from 60,000 km, especially with short-trip use and no warm-up. Whistling and smoke as symptoms.
Symptoms: Turbocharger can develop play from 60,000 km - !! Connecting rod bearing damage from oil neglect from 150,000 km
Neglected oil changes can cause connecting rod bearing failure — catastrophic engine damage. Regular oil changes every 15,000 km are non-negotiable.
Symptoms: Neglected oil changes can cause connecting rod bearing failure — catastrophic engine damage

Renault's legendary 1.5 dCi diesel engine (K9K) is considered exceptionally long-lived — 300,000 to 400,000 km with good maintenance are well documented. Early series had injector weaknesses; later 800-series variants are considerably more reliable. Strictly observe oil change intervals to prevent con-rod bearing damage.
