Does BMW Clock Spring Replacement Require Matching?
1 Answers
BMW airbag clock spring replacement requires matching. Clock Spring: The clock spring is used to connect the main airbag (the one on the steering wheel) with the airbag wiring harness, essentially serving as a segment of wiring. Since the main airbag needs to rotate with the steering wheel, it can be visualized as a wiring harness of certain length that coils around the steering column, appropriately unwinding or tightening in reverse as the steering wheel turns. Research: Automotive safety is divided into active safety and passive safety. Active safety refers to a vehicle's ability to prevent accidents, while passive safety refers to the vehicle's capability to protect occupants in the event of an accident. When an accident occurs, occupant injuries happen instantaneously. For example, during a frontal collision at 50 km/h, the entire event occurs within about one-tenth of a second.
