my Volkswagen Golf MK7.5 (2020-Present) dashboard lights keep flickering what should I do

Solution

1. Preparation

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

2. Inspect and Clean Battery Terminals

• Using a wire brush, clean the battery terminals and cable ends to remove any corrosion.
• Reconnect the battery terminals securely, starting with the positive terminal followed by the negative.

3. Alternator Testing

• Reconnect the battery and start the vehicle.
• Using a multimeter, measure the voltage output at the battery terminals with the engine running.
• If the voltage is outside the specified range (13.7-14.7 volts), replace the alternator.

4. Wiring Inspection

• Visually inspect the wiring harness for any frayed or damaged wires.
• For any damaged wires, use electrical tape to repair or replace the affected sections as necessary.

5. Fuse Replacement

• Locate the fuse box and identify any blown fuses related to the dashboard lights.
• Replace any blown fuses with the appropriate amperage rating.
