my Skoda Octavia NFL (2020-Present) dashboard warning lights are flickering

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, cleaning brush, electrical contact cleaner.
• Ensure the vehicle is parked on a flat surface and the engine is turned off.
• Disconnect the negative battery terminal to prevent any electrical shorts while working.

2. Clean Battery Terminals

• Remove the negative and positive battery terminals.
• Inspect for corrosion; if present, clean with a mixture of baking soda and water using a cleaning brush.
• Rinse with water and dry thoroughly.
• Reconnect the terminals securely, starting with the positive first.

3. Test Battery and Alternator

• Reconnect the battery and use a multimeter to measure the battery voltage.
  • If the voltage is low (below 12.4 volts), replace the battery.
• Start the engine and measure the voltage again at the battery terminals.
  • If the voltage is not within the 13.7 to 14.7 volts range, the alternator may need replacement.

4. Inspect Wiring and Fuse Box

• Visually inspect the wiring harness for any signs of damage, fraying, or loose connections.
• Check the fuse box for any blown fuses related to the dashboard and replace them as necessary.

5. Reassemble and Test

• Once all checks and repairs are complete, reconnect the negative battery terminal.
• Start the vehicle and observe the dashboard lights for any flickering.
