Re strange yellow tag: According to the following "rescue datasheet" PDF file, pulling out the yellow tag fuse is one of 3 possible ways to "Deactivate the high-voltage system" (400V battery), which is something that should be done in the event of an accident (item 8) or submersion in water (item 7):

By the way, the datasheet also advises how to tow an ID.3 following an accident, which involves deactivating the high-voltage system and towing on the car's front wheels rather than rear wheels (to avoid the drive axles). But in another thread, someone wrote that the parking brakes will automatically engage when the driver leaves the car. How to release the parking brakes for towing in this situation?
