What is the issue with the BMW passenger airbag deactivation?
1 Answers
Passenger airbag deactivation is a normal phenomenon. The passenger airbag in this vehicle can be manually turned off, so this "fault" simply indicates the airbag is in the deactivated state. Airbag service life: Beyond requiring replacement after deployment, airbags cannot remain functional indefinitely alongside the vehicle. As a critical automotive component, their lifespan doesn't necessarily match the car's longevity. Standard airbags are designed for 8-10 years of service. However, with updated vehicle retirement policies, many cars now remain operational for over a decade. Airbag system composition: The automotive airbag system consists of sensors, the airbag module, indicator lights, and an electronic control unit. While the airbag operates, a secondary monitoring system tracks its performance. The inflation process relies on chemical reactions to generate gas - these compounds can degrade with moisture exposure. Additionally, electrical connectors, grounding points may loosen over time, and sensors can fail.
