Why does the airbag light stay on in a Volvo v40?

The airbag light in a Volvo V40 may stay on due to several reasons, including a malfunction in the airbag system, such as a faulty sensor, wiring issues, or a problem with the airbag module itself. It can also indicate that the system has been disabled due to a detected fault. It's essential to have the vehicle diagnosed with a specialized scanner to identify the specific issue, as this is crucial for ensuring passenger safety. Ignoring the light could lead to the airbags not deploying in the event of an accident.
