Solution

1. Preparation

Gather tools including a multimeter, socket set, jumper cables, and a load tester.
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

Inspect Battery Terminals:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and battery posts with a mixture of baking soda and water.
- Reconnect the terminals securely.
Battery Testing:
- Reconnect the battery (positive first, then negative).
- Use a multimeter to check battery voltage; if below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
Jump-Start Procedure (if necessary):
- Connect jumper cables (red to positive terminals and black to negative terminals).
- Start the assisting vehicle and then attempt to start the Golf.
- If it starts, let it run for a while to recharge the battery.

3. Starter Motor Inspection

Check Connections:
- Locate the starter motor (usually near the transmission).
- Inspect the wiring and connections to the starter for any signs of damage or looseness.
Testing the Starter:
- With the battery connected, use a multimeter to check for voltage at the starter terminal when the ignition key is turned to the start position.
- If voltage is present but the starter does not engage, consider replacing the starter motor.
