Replacing the Pyrotechnic Actuator

If the crash sensitive head restraint has been deployed, the pyrotechnic actuator must be replaced by a BMW dealer. After replacing the pyrotechnic actuator, clear the fault memory. It is essential to follow the repair instructions.

Replacement of the pyrotechnic actuator does not require an explosives certificate in Germany.

The pyrotechnic actuator has been exempted from the explosives certificate requirement by the German Federal Materials Testing Office.
