my Skoda Octavia dashboard lights are flickering what's happening

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety during repairs.

Tools Required:

• Multimeter
• OBD-II scanner
• Socket set
• Screwdriver set
• Wire brush (for cleaning terminals)

2. Inspect and Clean Battery Connections

• Remove the battery terminals (negative first, then positive).
• Clean the terminals and battery posts with a wire brush until shiny.
• Reconnect the terminals (positive first, then negative) and ensure they are tight.

3. Test the Alternator

• Reconnect the battery and start the engine.
• Use a multimeter to measure the voltage across the battery terminals. It should read between 13.7 to 14.7 volts when the engine is running.
• If the voltage is outside this range, replace the alternator.

4. Replace Blown Fuses

• Locate the fuse box and identify any blown fuses related to the dashboard lights.
• Remove the faulty fuses and replace them with new fuses of the same amperage.

5. Repair Wiring and Connections

• Inspect the wiring harness for any damaged or frayed wires.
• Repair any damaged wiring with electrical tape or by replacing the affected sections.
• Ensure all connectors are secure and free of corrosion.
