Dacia Sandero 3
Weaknesses, engine ratings and buying advice
The Sandero III, built from 2020, carries on the winning formula: Europe's cheapest small car, now on the more modern CMF-B platform of the current Clio generation. It looks more grown-up and is technically tidier, but at its core it remains a deliberately simple hatchback focused on low purchase and running costs. Anyone after a near-new, thrifty daily driver without expensive extras will find one of the most sensible offers on the market.
The engine range has consolidated: there is only the 1.0-litre H4D three-cylinder now — either as a plain naturally aspirated unit or as a turbo in several output stages. The naturally aspirated engine is as simple and low-maintenance as it gets, but noticeably sluggish; for motorway use or loaded trips the turbo versions are the clearly better choice, delivering solid pull from low revs. The factory LPG turbo variants are especially worth recommending: autogas makes an already frugal engine extremely cheap to run. One important point across all H4D units: there are no hydraulic valve-clearance adjusters, so the valve lash must be checked at the specified interval. Keep an eye on the timing chain of the TCe turbos, along with the known oil-in-spark-plug-wells issue.
The budget character shows on the car itself: sound insulation is thin, the engine makes itself heard at higher speeds, and paint quality is below the class average — stone chips and light scratches show up faster. On CVT-automatic versions there are reports of jerking at constant speed; anyone wanting relaxed, low-hassle motoring is often better served by the manual. Add a minor but harmless annoyance: the indicator does not always self-cancel after a lane change.
As a young used car, the Sandero III is a very sensible choice. Favour the turbo over the naturally aspirated engine, prefer the LPG version if it interests you, take the valve-clearance and timing-chain topics seriously, and do not be put off by the cheap-feeling cabin. Anyone who values level-headedness over prestige gets an honest, robust and exceptionally cheap-to-run car here — more substance than the low price suggests.

Engine Overview
The Dacia Sandero 3 is available with 8 engine variants — from 67 to 110 hp. 2 variants had engine changes — the model year is crucial.
Naturally aspirated 1.0-litre three-cylinder without turbo — maximum simplicity with low maintenance requirements. No hydraulic tappets, so have valve clearance checked every 100,000 km. Timing chain can wear prematurely with excessively long oil change intervals; pay particular attention to the cooling system on this aluminium engine.
- !! Timing chain stretch on TCe variants from 140,000 km
Timing chain can stretch on the turbocharged variants (TCe) after 120,000–160,000 km. Cold-start rattling is an early warning sign.
Symptoms: Timing chain can stretch on TCe variants after 120,000 km - !! Oil in spark plug tubes from 90,000 km
Valve cover gasket leaks in the spark plug tube area. Same issue as the H4B three-cylinder.
Symptoms: Valve cover gasket leaks in the spark plug tube area - !! CVT gearbox judder from 90,000 km
CVT gearbox (X-Tronic) judders at constant speed. A software update may help; otherwise the variator belt is worn.
Symptoms: CVT gearbox (X-Tronic) judders at constant speed
The turbocharged version of the one-litre three-cylinder, offering noticeably more pulling power from the turbo and decent everyday performance. The engine has no hydraulic valve-lash adjusters, so valve clearances must be checked on schedule and adjusted as needed, otherwise rattling and rough running follow. The critical point is the timing chain: with over-long oil-change intervals or poor-quality oil it can stretch, announced by rattling on cold start. Short oil-change intervals and manufacturer-approved oil are the best prevention. Oil can also collect in the spark-plug wells — keep an eye on the rocker-cover gasket. Overall a modern downsizing engine that repays clean maintenance with reliability.

A turbocharged three-cylinder of one litre displacement — moderately powerful, but thanks to forced induction it offers decent torque from low revs. The characteristic three-cylinder note and a slight turbo lag at very low speeds are part of its nature. There are no hydraulic lifters, so valve clearances must be checked on schedule. The timing chain is the critical item: with overly long oil-change intervals or poor-quality oil it can stretch, announced by a cold-start rattle — short oil-change intervals and a flawless cooling system are therefore essential. As the rocker cover gasket ages, oil collects in the spark plug wells and causes misfires. Overall a modern, economical unit that nonetheless demands consistent care.

The most powerful version of the turbocharged 1.0-litre three-cylinder, lively and with strong pulling power in everyday use. The engine runs without hydraulic lifters, so the valve clearance must be checked regularly, at the latest every hundred thousand kilometres, and adjusted if needed. The timing chain can stretch over time and announces itself with a rattle on cold starts, making early inspection worthwhile. Oil in the spark plug wells points to leaking seals. Under heavier loads, ensure a proper warm-up phase and short oil change intervals, which protects the turbocharger.

A stronger turbo version of the 1.0-litre three-cylinder, here with a factory-fitted autogas system running in bi-fuel mode. The valvetrain has no hydraulic lifters, so valve clearance must be checked at the specified interval — gas operation increases valve seat wear, and excessive clearance otherwise leads to power loss and damage. The timing chain can stretch as on the petrol turbo variants and announces itself with rattling. Oil in the spark plug wells appears over time. The gas injectors are prone to fouling and should be serviced, while the gas tank is subject to mandatory recertification after around ten years and can corrode. Diagnostics of the gas system are limited with standard equipment.

A turbocharged one-litre three-cylinder running on factory LPG — lively and economical, but demanding careful maintenance. There is no hydraulic lash adjustment, so valve clearances need regular checks. The timing chain can stretch if oil servicing is deferred, making clean change intervals essential. Oil in the spark-plug wells appears over the years. Gas operation adds load to the valve seats, the gas injectors foul up and diagnostics of the gas system are limited; the tank requires its mandatory revision. The small turbo's cooling system deserves particular attention.
