✓ 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: Rattle for a few seconds on cold start, later camshaft/crankshaft correlation fault codes and engine light
Fix: Do not ignore the noise; measure chain stretch (live data or inspection) and replace chain, tensioner and guides; change oil more often than the long factory interval
Signs: Coolant level drops slowly, smell or traces of coolant, temperature warning; if missed the engine overheats
Fix: Check the coolant level regularly; replace the thermostat housing or water outlet with its seals; after any overheating check the head gasket
Signs: Misfire, rough running, flashing engine light, coolant level dropping without an outside leak
Fix: Do not just replace the coil: find where coolant enters the coil wells (dealer has a repair procedure on the engine); ask about goodwill on cars still young
Signs: Metallic rattle from the turbo when lifting off or at low load; sometimes power loss with an underboost code
Fix: Dealer ECU update (Renault technical note) for the rattle; for power loss check the turbo air hose and the boost control valve before replacing the turbo
Signs: Bonnet does not lock firmly or sits badly; on unfixed cars it may lift at speed.
Fix: Check by VIN at a Dacia dealer that the free recall (bonnet lock striker replacement) was done.
Signs: Fuel smell from the engine bay or visible wetness at the fuel line on unfixed cars.
Fix: Check by VIN that the free recall (fuel line replacement, under an hour) was done.
Signs: Dead dipped-beam bulb, faulty tail or brake light, or misaimed headlights noted at the inspection.
Fix: Check all lights and headlight aim before the inspection; replace bulbs or the lamp unit if a connector is corroded.
Signs: Flat battery after short standing or doors left open, low-voltage/charge messages, start-stop not working.
Fix: Test battery and charging and check for parasitic drain and software updates; replace with the correct EFB battery if weak.
Signs: One or more windows stop or work only intermittently, often rear doors.
Fix: Check switch and connector, then replace the window motor/regulator (often covered by warranty on young cars).
Signs: 'Check emergency call' message on many trips, especially in cold weather; infotainment freezes, black screen or CarPlay drops.
Fix: Check battery voltage first, then have the dealer install software updates; replace the eCall module or head unit only if updates fail.
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Judder pulling away, engine revs flare without the car speeding up, delay when selecting D or R, power cut / limp mode when hot
Fix: Read the CVT codes and check the fluid for metal; if caught early replace the valve body and fluid and flush the cooler, otherwise fit a reconditioned CVT
Signs: Whine or howl under acceleration that rises with engine or road speed, fluid level and pressures otherwise normal
Fix: Have a CVT specialist confirm which bearing is noisy; replace the bearings during an overhaul or fit a reconditioned gearbox before debris damages the pulleys
Typical routine maintenance cost for 100,000 km: €2,200–4,950. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
