my Skoda Octavia won’t start and just clicks what should I do

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, wrench set, battery terminal cleaner.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

1. Check Battery Condition
   • Inspect the battery for swelling or leaks.
   • Clean any corrosion on terminals using a battery terminal cleaner.
2. Test Battery Voltage
   • Use a multimeter to measure the battery voltage. If below 12.4 volts, recharge or replace the battery.
3. Replace Battery (if necessary)
   • Remove the positive terminal first, followed by the negative terminal.
   • Remove any securing brackets and lift the battery out.
   • Install the new battery by placing it in the tray, securing it with brackets, and connecting the positive terminal first followed by the negative terminal.

3. Starter Motor Inspection

1. Access the Starter Motor
   • Locate the starter motor (typically near the transmission).
   • Remove any components blocking access (e.g., air intake duct).
2. Check Connections
   • Ensure all electrical connections to the starter motor are tight and free of corrosion.
3. Test Starter Motor
   • Connect a jump lead directly to the starter motor from the battery to see if it engages.
   • If it does not engage, the starter motor may need replacement.

4. Ground Connections

1. Inspect Ground Wires
   • Locate the ground strap from the battery to the chassis and from the engine to the chassis.
   • Ensure connections are clean and tight; clean or replace if corroded.
