my Skoda Octavia NFL (2020-Present) dashboard lights are flickering, what could it be?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery negative terminal to ensure safety.

2. Clean Battery Terminals

• Remove the battery cables from the battery terminals.
• Clean the terminals and cable clamps with a wire brush until shiny.
• Reconnect the cables securely, ensuring tight connections.

3. Replace Battery (if necessary)

• If the battery voltage is below 12.4V or if it is old (more than 3-5 years), replace it.
• Remove the old battery by unfastening the bracket and disconnecting the cables.
• Install the new battery securely and connect the cables, following polarity.

4. Check and Replace Alternator (if necessary)

• If the voltage output from the alternator is below 13.8V, consider replacing the alternator.
• Remove the serpentine belt by loosening the tensioner.
• Disconnect the alternator wiring harness and remove mounting bolts.
• Install the new alternator and reconnect the wiring harness and serpentine belt.

5. Inspect Wiring and Fuses

• Visually inspect all wiring harnesses for damage or wear.
• Replace any damaged wires and ensure all connectors are secure.
• Check the relevant fuses (dashboard lights and electrical system) and replace any that are blown.
