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

Solution

1. Preparation

• Tools Required: Multimeter, socket set, wrench set, screwdriver, replacement battery (if needed), replacement fuses (if needed)
• Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
• Disconnect the battery negative terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

1. Check Battery Voltage:

   • Reconnect the battery negative terminal.
   • Measure the battery voltage with a multimeter.
   • If the voltage is below 12.4 volts, proceed to replace the battery.

2. Replace Battery:

   • Remove the battery hold-down clamps using a socket set.
   • Disconnect the positive terminal first, followed by the negative terminal.
   • Lift the old battery out and replace it with a new, fully charged battery.
   • Reconnect the positive terminal first, then the negative terminal, ensuring tight connections.

3. Starter Motor Inspection

1. Test Starter Motor:
   • Disconnect the battery negative terminal.
   • Locate the starter motor and check its electrical connections for tightness and corrosion.
   • Use a jumper wire to connect the starter motor’s solenoid terminal directly to the battery positive terminal to test the motor.
   • If the starter engages and turns the engine over, the starter motor may need replacement.

4. Fuse and Relay Check

1. Inspect Fuses:

   • Open the fuse box and locate the starter fuse.
   • Remove the fuse and check for continuity using a multimeter.
   • Replace any blown fuses with a new one of the same amperage.

2. Check Starter Relay:

   • Swap the starter relay with a similar relay in the fuse box.
   • Attempt to start the vehicle again. If it starts, replace the faulty relay.
