how to reset the check engine light on Volkswagen Tiguan First Generation (2007-2018)?

Solution

1. Preparation

• Gather tools: OBD-II scanner, vehicle key, and possibly a battery terminal tool.
• Ensure the vehicle is parked on a flat surface with the engine off.

2. Connect OBD-II Scanner

• Plug the OBD-II scanner into the vehicle's OBD-II port, usually located under the dashboard near the steering column.
• Turn the vehicle’s ignition to the "ON" position without starting the engine.

3. Access Error Codes

• Follow the on-screen instructions on the OBD-II scanner to read and clear error codes.
• If no codes are found, proceed to reset the light.

4. Reset Check Engine Light

• Use the scanner's "Erase Codes" or "Clear Codes" function.
• Confirm the action when prompted by the scanner.

5. Disconnect the Battery (optional)

• If the scanner does not reset the light, disconnect the negative battery terminal for about 10-15 minutes to reset the ECU.
• Reconnect the battery terminal securely.
