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

Solution

1. Preparation

• Gather tools: multimeter, socket set, wrench set, OBD-II scanner, jumper cables.
• Ensure the vehicle is in park (automatic) or neutral (manual).
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Battery Inspection

• Sub-steps:
  1. Reconnect the battery and measure the voltage; if it’s below 12.4 volts, charge or replace the battery.
  2. Clean the battery terminals with a wire brush to remove corrosion.
  3. Tighten the battery terminal connections securely.

3. Starter Motor Testing

• Sub-steps:
  1. Locate the starter motor (usually at the lower part of the engine near the transmission).
  2. Remove the electrical connector from the starter.
  3. Use jumper cables to connect the positive terminal directly to the starter solenoid terminal and the negative to the starter case.
  4. If the starter engages and the engine cranks, the starter is functioning, and the issue may lie in the ignition circuit.

4. Ignition Switch and Fuses

• Sub-steps:
  1. Inspect the ignition switch for any signs of wear or damage, and replace if necessary.
  2. Check the relevant fuses in the fuse box (refer to the owner's manual for fuse location) and replace any that are blown.

5. Final Assembly

• Sub-steps:
  1. Reconnect the battery terminal snugly.
  2. Ensure all electrical connections are secure.
  3. Reassemble any components that were removed during inspection and testing.
