my Skoda Octavia NFL (2020-Present) won't start and makes a clicking noise, what to do?

Solution

1. Preparation

• Tools Required:
  • Socket set
  • Multimeter
  • Battery terminal cleaner
  • Torque wrench
• Ensure the vehicle is in park or neutral with the parking brake engaged.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

• Sub-steps:
  1. Clean the battery terminals using a battery terminal cleaner to remove any corrosion.
  2. Reconnect the battery terminals securely.
  3. If the battery voltage is low or the load test indicates failure, replace the battery with a new one.
  4. Ensure the new battery is properly secured and connections are tight.

3. Starter Motor Inspection

• Sub-steps:
  1. Locate the starter motor (usually on the lower side of the engine near the transmission).
  2. Disconnect the electrical connectors from the starter motor.
  3. Inspect the connections for corrosion or damage; clean or replace as necessary.
  4. If the starter motor is faulty, remove it using a socket set and replace it with a new starter motor.
     • Torque bolts to manufacturer specifications (refer to service manual for exact values).

4. Relay and Fuse Replacement

• Sub-steps:
  1. Locate the fuse box and identify the starter relay.
  2. Swap the starter relay with a similar relay from the fuse box to test functionality.
  3. If the vehicle starts, replace the faulty relay.
  4. Inspect and replace any blown fuses related to the starting system.
