📖Dacia Sandero III (2020-2022): class-leading refinement meets ultra-low running costs

Dacia Sandero Phase 3 (2020-Présent)

Introduced in late 2020 on the CMF-B platform, the third-generation Sandero transformed Dacia from a budget compromise into a competitive class leader. Compared to European rivals like the Toyota Yaris and Peugeot 208, it delivers impressive ride comfort, improved soundproofing and modern tech, where systematic Dacia Sandero maintenance protects advanced 3-cylinder turbo engines and high-efficiency bi-fuel setups.

The powertrain range features the naturally aspirated 1.0 SCe 65, the lively 1.0 TCe 90 and the dual-fuel ECO-G 100 LPG bi-fuel system, with the optional CVT automatic gearbox available on the TCe 90. The 1.0 TCe unit utilizes a durable timing chain and electronic wastegate, which require clean synthetic oil to avoid premature wear. The ECO-G 100 delivers unmatched running economy, provided both LPG gas filters are renewed on schedule.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Modern CMF-B platform delivers dramatically improved ride comfort, noise insulation and crash protection.
  • The ECO-G 100 LPG bi-fuel setup drastically reduces fuel expenditures whilst retaining full petrol capability.
  • Punchy and efficient 1.0 TCe 90 engine paired with either a crisp 6-speed manual or smooth CVT gearbox.
  • Extremely generous interior dimensions with class-leading rear legroom and a commodious 328-litre boot.

Chronic weak spots

Keep an eye on
  • 1.0 TCe 90: change oil at strict 15,000 km intervals, allow proper warm-up and listen for electronic turbo wastegate chatter.
  • ECO-G 100 LPG system: inspect gas vapour hoses, verify crisp petrol-to-LPG switching and replace dual LPG filters on time.
  • CVT automatic transmission: test acceleration from a standstill to verify smooth torque transfer and ensure no rev flair.
  • Front suspension in urban usage: check anti-roll bar drop links, lower wishbones and front tyre shoulder wear.
  • Interior electronics: check Media Display touchscreen responsiveness, reversing camera operation and ADAS sensor calibrations.

Critical deadlines

Do not miss
  • Engine oil and filter change every 15,000 km or 12 months using Renault RN17 specification 5W-30 synthetic oil.
  • LPG bi-fuel filtration renewal (both liquid and gaseous phase filters) every 30,000 km or 24 months.
  • Spark plug replacement every 30,000 km on ECO-G models (every 60,000 km on standard TCe petrol).
  • Brake fluid replacement and CVT transmission health check every 60,000 km or 36 months.
