Notes on scrapping vehicles with gas generators (airbag system) (530i 2017-2022, 530i xDrive 2017-2022, 530e PHEV 2018-2022, 530e xDrive PHEV 2018-2022, 540i 2017-2022, 540i xDrive 2017-2022, M550i xDrive 2018-2022)

The gas generator is a pyrotechnic component and is for the most part permanently mounted on the following components: 

• Airbag module 
  • Driver's/front passenger airbag
  • Side airbag
  • Head airbag
  • Knee airbag
• Electromotive automatic reel
• Belt end fitting tensioner
• Seat belt tensioner
• Safety battery terminal
• Active head restraint

In accordance with accident prevention regulations and specific national regulations, gas generators must be rendered unusable before they are scrapped. This is necessary because pyrotechnical objects can cause injury if improperly activated (e.g. scrapping with flame cutters).

In vehicles intended for scrapping it is paramount prior to draining and further stripping work to ensure that all gas generators in the vehicle  have been activated. The fired gas generators can then be scrapped together with the vehicle.

Gas generators that have not fired constitute a hazard (also to the environment)! 

Ignition failure: 

If correct ignition is not possible, the relevant components must be removed and disposed of by special waste disposal companies!

Comply with safety regulations for handling airbag system components. 

If an ignition has failed: 

• Disconnect the igniter from the vehicle battery and
• Wait a few minutes before approaching the vehicle

The components of an airbag system must always be disposed of. Such components must not be sold on as used parts. 

Ignition: 

Ignition of the gas generators may only be carried out by expert personnel and under the supervision of a responsible person. Other standard accident prevention regulations (safety goggles, ear defenders etc.) must also be observed.

The gas generators must be fired from the outside in this vehicle which has been earmarked for scrapping.

In this process 

• The doors must be closed
• The tailgate must be open
• The side windows must be open and
• Slide/tilt sunroof open

Use igniters with the appropriate cables to activate the gas generators.
