my Volkswagen Golf Seventh Generation (2013-2020) won’t start and just clicks what should I do

Solution

1. Preparation

• Gather tools: Multimeter, OBD-II scanner, jumper wires, socket set, torque wrench, safety gloves, and eye protection.
• Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Maintenance

1. Disconnect Battery

   • Use a socket set to disconnect the negative terminal first, followed by the positive terminal.
   • Safety Warning: Always disconnect the battery before working on electrical systems.

2. Clean Battery Terminals

   • Inspect and clean the battery terminals with a wire brush to remove any corrosion.
   • Reconnect the battery terminals securely, starting with the positive terminal.

3. Starter Motor Testing

1. Locate Starter Motor

   • Refer to the vehicle manual and locate the starter motor.

2. Bypass Starter Motor

   • Use jumper wires to connect the positive terminal on the battery to the starter motor's terminal.
   • Ensure safety measures are in place to prevent accidental shorting.
   • If the starter engages and the engine cranks, the issue lies within the ignition or wiring.

4. Replace Faulty Components

1. Replace Battery

   • If the battery is found to be weak or faulty, replace it with a new battery of the same specifications.
   • Use a torque wrench to secure battery terminals to the manufacturer’s recommended torque settings.

2. Replace Starter Motor

   • If the starter motor is faulty, remove it using the socket set, following any specific manufacturer instructions.
   • Install the new starter motor and secure it in place with the appropriate torque.
