Volkswagen Golf MK7 (2015-2019) airbag light on how to reset it

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torx screwdriver, and safety gloves.
• Ensure the vehicle is parked on a level surface and the ignition is turned off. Disconnect the battery by removing the negative terminal to avoid accidental deployment of airbags.

2. Retrieve and Clear Codes

• Connect the OBD-II scanner to the vehicle's diagnostic port.
• Turn the ignition to the "On" position without starting the engine.
• Follow the scanner's prompts to read the diagnostic trouble codes (DTCs).
• Write down any codes for reference.
• Clear the codes using the OBD-II scanner's "Erase" function.

3. Reconvene Connections

• Reconnect the negative battery terminal securely.
• Check all airbag connectors to ensure they are properly seated and free from corrosion.
• If any connections were loose, reseat them and ensure they are secure.

4. Reset Airbag System (If Necessary)

• If the airbag light remains on after clearing the codes, use the OBD-II scanner to perform a reset function specific to the airbag system, if supported by the tool.
• Follow the scanner's instructions to complete the reset.

5. Final Check

• Reconnect the battery and start the vehicle.
• Allow the vehicle to run for a few minutes and check if the airbag light remains off.
• If the light comes back on, further diagnosis may be required.
