Europe's cheapest new car with factory-fitted LPG, offering genuinely low fuel costs at around 6.5 litres of LPG per 100 km. Built on the same CMF-B platform as the Renault Clio V, the ECO-G version uses the H4D 1.0 TCe engine with a dedicated bi-fuel system integrated at the factory. The LPG tank sits in the spare wheel well and Dacia specifies 40 usable litres in addition to the 50-litre petrol tank. Dacia's October 2025 European model update replaced this 1.0-litre ECO-G 100 with the 1.2-litre ECO-G 120.· more· less

Metallic rattling between 1,000 and 2,100 rpm, most common on early 2021 production cars · more· less
The turbo wastegate actuator develops play over time, producing a distinctive metallic rattle at low revs. Early production cars (2020-2021) are most affected. Dacia often classifies this as a characteristic of the engine rather than a defect. Models produced after mid-2021 benefited from improved components. If only the actuator is worn, specialist repair costs around 400-600 euros. If the turbo internals are also damaged, full turbo replacement runs 800-1,500 euros including labor. The rattle itself is cosmetic in early stages but can worsen if ignored. Running on LPG does not appear to worsen this issue compared to petrol-only models.
LPG injector rail wear
€200 - 6002 of 7
Injector coils degrade over time, forcing the car to switch back to petrol with warning light · more· less
The factory ECO-G LPG system uses dedicated injectors that can wear, particularly if LPG filters are not replaced at the correct intervals. When one or more injector coils fail, the cylinder runs lean on LPG, triggering an LPG injection warning and forcing a switch to petrol. Dacia does not sell individual injectors separately, so the entire rail must be replaced and recalibrated. Typical replacement cost is 200-450 euros at an LPG specialist, or up to 600 euros at a Dacia dealer. The risk increases after 60,000 km and is accelerated by poor-quality LPG or skipped filter services. Keeping both gas-phase and liquid-phase filters fresh significantly extends injector life.
LPG reducer/vaporizer malfunction
€150 - 3503 of 7
Internal diaphragm degrades, causing lean/rich mixture codes only when running on LPG · more· less
The LPG reducer converts liquid LPG to gas before injection. Over time, the internal diaphragms and pressure regulators can develop instability, particularly at high operating temperatures after prolonged motorway driving. Symptoms include rough running, hesitation under acceleration, and P0171 or P0172 fault codes that appear only when running on LPG. The car typically switches to petrol without issue. Reducer overhaul or replacement costs 150-300 euros at an LPG specialist. This is more common after 80,000 km and in cars driven primarily on LPG with infrequent petrol use. Annual LPG system inspections help catch this early.
Engine management light and software faults
€50 - 4004 of 7
Random check engine light, sensor communication errors, especially on 2021-2022 cars · more· less
Several owners report random engine management warnings, particularly on early production cars. Symptoms include intermittent check engine light, occasional failure to start on first attempt, and erratic idle after cold start. The root cause is often software-related, with Dacia releasing ECU updates to address sensor communication issues. Most occurrences are resolved by a software update at the dealer (free under warranty, 50-100 euros diagnostic fee otherwise). In rare cases, a faulty mass airflow or oxygen sensor needs replacing at 150-400 euros. The bi-fuel ECU is more complex than the petrol-only version, adding potential failure points.
Front stabilizer bar link wear
€100 - 2505 of 7
Anti-roll bar links develop knocking over bumps after 30,000-60,000 km · more· less
The front stabilizer bar links are basic in design and tend to wear earlier than on more expensive rivals. Typical symptoms include knocking or clunking over bumps, especially at low speed. Parts are very cheap (10-30 euros per link) and labor is straightforward. The rear axle silentblocks can also develop play on higher-mileage cars, causing slight swaying at highway speeds. Total repair cost for both front links including labor is typically 100-200 euros at an independent shop. This is a wear item rather than a defect, but it occurs sooner than expected on many Sanderos.
MediaNav infotainment failure
€0 - 4006 of 7
Screen goes blank, freezes on boot logo, or overheats in direct sunlight · more· less
The LG-supplied MediaNav unit has documented issues across Dacia and Renault models. Symptoms include the screen going blank, freezing on the boot logo, touchscreen becoming unresponsive, and overheating-related lockups in hot weather. Dacia has acknowledged issues with the LG units. A firmware update sometimes resolves software-related freezes. Disconnecting both battery terminals for 20 minutes can also resolve temporary issues. If the unit fails completely, aftermarket replacement costs 200-350 euros while an OEM unit from Dacia costs 400 euros. The problem affects a minority of cars but is well-documented on owner forums.
Premature clutch wear
€500 - 9007 of 7
LPG's different torque profile increases clutch disc wear in heavy urban traffic · more· less
The LPG version produces a slightly different torque curve at low revs compared to petrol, which puts additional stress on the clutch disc. Combined with the stop-start system's frequent re-engagement, some owners report clutch judder or slipping earlier than expected, particularly in predominantly stop-and-go city driving. Unlike the heavier Jogger, the Sandero's lighter weight means this is less of a concern, and most cars reach 80,000-120,000 km without clutch issues. A full clutch kit replacement costs approximately 500-900 euros depending on the shop.
Budget-friendly with manageable LPG-specific maintenance
The Sandero ECO-G shares the generally reliable 1.0 TCe engine with the petrol-only version, adding a well-integrated but maintenance-dependent LPG system. The turbo wastegate rattle is the most commonly reported issue and is mostly cosmetic in early stages. LPG-specific risks (injector rail, reducer, pressure sensor) are preventable with regular filter changes. Parts and labor costs are among the lowest in the segment. Keep up with the LPG filter services (Dacia UK specifies the gas-phase filter every 18,000 miles, about 29,000 km, and the liquid-phase filter every 36,000 miles, about 58,000 km) and oil changes every 15,000 km, and the ECO-G should deliver reliable, very affordable motoring.
Service history
Complete Dacia dealer or specialist records essential. Verify both standard and LPG-specific services have been performed.
Tires
Check tread depth, age (date codes), and uneven wear. Standard size is 185/65 R15.
Cold start
Start engine completely cold on petrol. Listen for timing chain rattle and turbo wastegate noise in first 30 seconds.
Test drive
Minimum 20 minutes including urban and highway driving. Test switching between petrol and LPG.
Specific for this vehicle
Switch to LPG during test drive
After the engine is warm (5+ minutes), switch to LPG and drive for at least 10 minutes. Check for rough running, hesitation under acceleration, or the system switching back to petrol unexpectedly.
Listen for turbo wastegate rattle at low revs
Rev engine between 1,000 and 2,100 rpm and listen for metallic rattling. Some rattle is considered normal by Dacia, but loud or persistent noise indicates worn actuator.
Check for LPG injection warning light
An LPG injection warning on the dashboard indicates a pressure sensor or injector fault. This should be resolved before purchase.

Verify LPG tank welding recall (Feb-Jul 2023)
Cars built between February and July 2023 may be affected by the LPG tank welding defect recall. Verify with Dacia using VIN.
Inspect LPG filler valve and connections
Check the LPG filler valve for damage or leaks. Smell for gas around the engine bay with the engine running on LPG. The ten-year tank re-certification often quoted applies to legacy tanks built before April 2006 without ECE R67 approval; a factory ECE-R67 car like this one has its gas system inspected as part of the general roadworthiness test instead.
Inspect paint for chips on door edges and sills
Dacia uses thinner paint without protective film. Check door edges, sills, and wheel arches for chips or early corrosion.
Test front suspension for knocking over bumps
Drive slowly over speed bumps. Listen for clunking from front anti-roll bar links.
