For VWs with driver or passenger side airbags:
The VW shop manual calls for a special safing dongle to be inserted into a plug on the seat before removing the seats from the car.
I haven't had a chance to research this, but I suspect this step is just to prevent a buildup of static charge from being able to set off the airbags (generated by hands rubbing on seats, seats rubbing on floor, etc.)
The dongles are only like $13 - depending on your year it might be tool VAS5232/1.
Setting off the airbag this way seems very unlikely, but one of the Adverse Events the phase 2 Moderna vaccine team had to report was "test subject struck by lightning" ... just sayin'. So, if you have a VW and skip this step, please keep a gopro running and promise to link the vid here.
