Dacia Sandero Dashboard Warning Lights and Meanings (2025 Complete Guide)

Driving your Dacia Sandero safely requires more than good handling—it means understanding what every dashboard warning light is trying to tell you. In this complete guide, we cover all Dacia Sandero warning lights, their meanings, levels of urgency, and what to do when one illuminates.

Understanding Dacia Sandero Warning Light Colors

Dacia organizes dashboard lights by color. Each color signals the urgency level of the issue:

🔴 Red Warning Lights (Critical Alerts)

1. Engine Temperature Warning Light

Indicates the engine is overheating. Stop immediately, switch off the engine, and let it cool. Continuing to drive may cause severe engine damage.

2. Oil Pressure Warning Light

Shows low engine oil pressure. Pull over, turn off the engine, and check the oil level. Driving further could lead to engine failure.

3. Battery Charging System Warning Light

Signals a problem with the charging system — usually the alternator or battery. Turn off all unnecessary electrical accessories and drive cautiously to a mechanic.

4. Brake System Warning Light

May indicate that the handbrake is engaged or the brake fluid is low. Check immediately — low brake fluid could compromise your stopping power.

5. Airbag Malfunction Light

If this light stays on, the airbag system may be disabled. Visit a Dacia service center as soon as possible.

6. Seat Belt Reminder Light

Glows when a seat belt isn’t fastened. Always secure all seat belts before driving.

7. Steering System Warning Light

Points to a malfunction in the electronic or hydraulic steering system. You may notice heavier steering or loss of power assist.

8. All-Wheel Drive (AWD) Fault Light

If illuminated, your Dacia’s AWD system has a malfunction. Drive with caution and book a diagnostic test soon.

9. Service Electric Parking Brake Light

Indicates a failure in the parking brake system. Do not park on slopes until checked by a technician.

10. Transmission Temperature Warning

Warns that the gearbox is overheating. Stop and allow it to cool down before driving again.

🟠 Amber / Yellow Warning Lights (Cautionary Alerts)

1. Check Engine Light (Malfunction Indicator)

The most common warning — it means the engine control system has detected a fault.
If flashing: stop immediately.
If steady: schedule a service soon.

Common causes include:

• Faulty oxygen (lambda) sensor
• Catalytic converter issues
• EGR or DPF faults
• Misfires or bad fuel quality

2. Diesel Particulate Filter (DPF) Warning

Appears in diesel versions. It means the filter is clogged with soot. Drive for 10–15 minutes at highway speed to help regeneration. If it persists, service is needed.

3. Glow Plug Warning Light

Found on diesel models. If it flashes after startup, the glow plugs or heating circuit may be faulty.

4. ABS Warning Light

Indicates a fault in the anti-lock braking system. Brakes will still function, but without anti-lock support. Drive carefully and repair soon.

5. Traction Control / ESP Warning

Shows when traction control or electronic stability control is active, or if a fault is detected.

6. TPMS (Tire Pressure Monitoring System) Warning

A yellow light shaped like a tire with an exclamation mark. Check your tire pressures; one or more may be low.

7. Loose Fuel Cap Warning

Alerts that the fuel filler cap isn’t properly tightened — which can also trigger a check engine light.

8. Water in Fuel Filter Warning

Specific to diesel models. Indicates excess water in the fuel filter, which should be drained promptly.

9. Lane Departure Warning Light

Activates when your car deviates from its lane without signaling.

Flashes briefly when the alarm system is active or during immobilizer operation.
