what dose it mean crash active?
Starting in the 2009 model year the head restraints in the 3 series (probably others but I'm not positive), have a component that shoots them forward in a rear-end collision to reduce neck injuries from your head snapping back.

The wire coming out of each one is the connection for the crash-active electronics.
