I just turn the airbag 180° and reattach it on one corner.

(This keeps zero stress on the cable/connector). It will get in the way of doing a full door shut test until you flip it back but you can latch the door with a big screwdriver etc for initial testing.

I might have a picture in a thread. Search awr-fix in titles in pretty sure I made a repair guide for DHC. Also put a zip tie preferably steel around the weak point.

If using non oem make sure the spring doesn't stick out there's almost zero tolerance it will scrape the window ask me how I know.
Not the wife's fault it's a design defect. BMW enginerds being goofy cute in at least three ways they messed up that design.
