why does my Volkswagen Tiguan make a clicking noise when I try to start it

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
• Ensure the vehicle is in park (or neutral for manual transmissions) and the parking brake is engaged.

2. Battery Replacement (if battery is faulty)

1. Disconnect the negative terminal first, followed by the positive terminal to avoid electrical shorts.
2. Remove the battery hold-down bracket and lift the old battery out.
3. Clean the battery tray and terminals with a battery terminal cleaner.
4. Install the new battery in the reverse order: place it in the tray, secure it with the hold-down bracket, and connect the positive terminal first, then the negative terminal.

3. Starter Motor Replacement (if starter is faulty)

1. Disconnect the battery as outlined above.
2. Remove any components obstructing access to the starter (e.g., air intake or engine covers).
3. Disconnect the wiring harness and the battery cable from the starter motor.
4. Remove the starter motor mounting bolts using a socket set.
5. Carefully extract the starter motor from its mounting location.
6. Install the new starter motor by reversing the removal steps, ensuring all electrical connections are secure.
7. Reconnect the battery terminals and check tightness.
