my Skoda Octavia dashboard lights keep flickering, what could be wrong?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the ignition is off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

• Tools Required: Wrench, wire brush (if needed)
• Check battery terminals for tightness; clean any corrosion with a wire brush.
• Reconnect the negative terminal and proceed to test the battery voltage (should be around 12.6V).

3. Alternator Testing

• Tools Required: Multimeter
• Start the engine and measure the alternator output at the battery; it should read between 13.8V to 14.4V.
• If the voltage is outside this range, replace the alternator.

4. Fuse Box Examination

• Tools Required: Fuse puller or pliers
• Inspect fuses related to the dashboard lights; replace any blown fuses with the correct amperage rating.
• Ensure that the fuse box itself is clean and free from corrosion.

5. Wiring Inspection

• Tools Required: Circuit tester, multimeter
• Visually inspect wiring harnesses for damage or wear.
• Use a circuit tester to check for continuity in affected circuits.
• Repair or replace any damaged wiring as necessary.
