Dacia Duster
Renault's 1.6-litre 16V naturally aspirated engine is one of the most robust engines in the Renault family — mileages above 300,000 km are well documented. The variable valve timing unit can cause rattling noises. LPG variant with factory-fitted LPG system; observe 10-year tank re-certification and have injectors checked regularly.
Sensible LPG variant
The 1.6 16V with LPG in the Duster offers solid performance at low fuel costs. A sensible compromise.
Engine Weaknesses 8
Timing belt and water pump due every 120,000 km or 6 years. More involved replacement than on the K7M due to the 16V head.
Symptoms: Timing belt and water pump due every 120,000 km
VVT oil control valve fouls and sticks. Rattling on cold start; power loss. Clean or replace the solenoid valve.
Symptoms: VVT oil control valve fouls and sticks
Ignition coil housing develops hairline cracks; moisture ingresses. Engine runs on 3 cylinders; misfires in wet conditions.
Symptoms: Ignition coil housing develops hairline cracks; moisture ingresses
LPG burns hotter than petrol — valve seats wear faster. Check valve clearance every 30,000 km. Hardened valve seats fitted from the factory.
Symptoms: LPG burns hotter than petrol — valve seats wear faster
LPG tanks must be inspected and replaced if necessary after 10 years (mandatory inspection). Internal corrosion from condensation is possible.
Symptoms: LPG tanks must be inspected after 10 years
Throttle body fouls with blow-by gases. Rough idle and hesitation when pulling away. Regular cleaning recommended.
Symptoms: Throttle body fouls with blow-by gases
Landi Renzo LPG injectors foul up over time. Replace the gas filter every 15,000 km. Rough running in LPG mode is a symptom.
Symptoms: Landi Renzo LPG injectors foul up over time
LPG ECU (Landi Renzo) is encrypted — only specialist workshops can read it. Regular Dacia dealers are often unable to diagnose it.

Vehicle Weaknesses 9
Axle components on the Duster I are flagged at the very first MOT — the defect rate is five times the average for comparable vehicles. A serious weak point of the first Duster.
A recall was issued for 4×4 models of model years 2010–2011 because snow packing could cause the rear brake lines to burst.
On models produced March to June 2014, rear axle springs were reported that could disengage from their spring seats.
Headlights and rear lights on the Duster I show double-digit defect rates. The low-beam headlights and rear lights in particular are flagged extremely often at MOT.
The Duster I develops increased oil loss already after a few years. Leaks at the engine and gearbox are typical and appear regularly from the fifth year onwards at MOT.
The Duster I air conditioning shows increased failures from around 70,000 km due to compressor damage, refrigerant loss and faulty condensers.
The fuel gauge tends to get stuck in the middle and stops moving despite a full or empty tank. Replacement of the entire fuel sender unit is often required.
The Duster I windscreen is known for frequent cracking, even without direct stone chip impact. Thermal stress and manufacturing tolerances encourage crack formation.
The manual gearbox produces a howling noise at higher speeds (90–120 km/h) in 4th–6th gear. By design due to the internal tooth geometry. A gearbox oil change can reduce the noise.
Reports & Tests
Defect rate rises above 35% on older vehicles. Low beam and tail lights fail five times more often than average. Oil loss and suspension critical.
