Dacia Sandero
Structurally simple, robust 1.6-litre naturally aspirated engine with high mileage potential. The water pump is the weak point: if it fails, head gasket damage threatens. LPG variant with factory-fitted LPG system; observe 10-year tank re-certification and have injectors checked regularly.
Economical on gas
The 1.6 with LPG saves at the pump. Performance is adequate; the boot shrinks slightly due to the gas tank.
Engine Weaknesses 8
Timing belt due every 60,000–90,000 km. Not interference-free — a snapped belt means valve damage and total engine failure.
Symptoms: Timing belt due every 60,000–90,000 km
Trigger wheel shifts due to crankshaft axial play. TDC sensor loses signal; engine fails to start or runs rough.
Symptoms: Trigger wheel shifts due to crankshaft axial play
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
Same weakness as the K7J — valve fouls, engine stalls at idle. Cleaning usually helps.

Valve cover gasket becomes porous after 100,000+ km. Oil loss visible at the cylinder head. Inexpensive to replace.
Symptoms: Valve cover gasket becomes porous after 100,000 km
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 7
Recall for vehicles produced between September and October 2016 due to possible detachment of brake caliper clips, which could cause the brake line to fracture.
Defective alternators have been reported on the Sandero II and can lead to sudden loss of electrical supply.
Faults in the steering column stalk of the light switch unit cause unreliable low beam operation. A known weak point that can result in MOT defects.
Suspension components, wishbones, and driveshafts show disproportionately high defect rates on the Sandero II from the second MOT. Tie rod ends and steering joints are regular weak points.
From the second MOT, brake discs show above-average wear. Braking performance on the brake tester frequently falls short.
The Sandero II shows early signs of corrosion on the underbody and sills after just a few years. Corrosion protection quality is well below the class average.
Battery failures are particularly common on early Sandero II model years. Disproportionately high breakdown reports, especially for the first years after market launch.
Reports & Tests
Defect rate of 8.2% on 2–3-year-old vehicles (average: 5.5%). Weak points: lighting, brake discs, exhaust emissions, and oil loss.
