my Skoda Octavia NFL (2020-Present) won't start and just clicks, what should I check?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is in a safe, well-ventilated area.
• Disconnect the battery negative terminal to prevent accidental short circuits.

2. Battery Inspection and Replacement

• Sub-steps:
  1. Remove the battery terminals, starting with the negative terminal.
  2. Clean the battery terminals with a wire brush to remove corrosion.
  3. Use the multimeter to measure the battery voltage; if below 12.4 volts, charge or replace the battery.
  4. If replacing, disconnect the battery hold-down clamp and remove the old battery.
  5. Install the new battery, ensuring the positive terminal is connected first, followed by the negative terminal.

3. Starter Motor Testing and Replacement

• Sub-steps:
  1. Reconnect the battery and check for voltage at the starter solenoid when attempting to start the vehicle.
  2. If there is no voltage, check the ignition switch and wiring harnesses for faults.
  3. If voltage is present but the starter does not engage, remove the starter motor.
  4. Inspect the starter for wear and test it using a bench test. If faulty, replace it with a new starter.
  5. Reinstall the starter and reconnect all wiring securely.
