I noticed you have GT1, by the screenshots. Now, go into TIS and see how to replace the air bags (rear). I know I did it a few months ago. BMW is very peculiar about how to remove the air lines and how to re-install them. You said the air bags are new. So my take is that whoever changed the airbags, either over tightened the air lines (TIS mentions 4 Nm if I'm not mistaken, which is very little - and if the nut is over tightened, it might leak) and you might need to replace some parts (minor $$$), or when re-installing them, the air lines were dirty, and the smallest amount of debris will do it. So you need to open the TIS, and inspect the air connections. Inspect thoroughly #15 and #2 in this diagram

Bingo! I suspected this might be the issue before you mentioned it, but when you replied I went out today since it was a little warmer and checked that fitting (#15) and saw this after I sprayed it with soapy water.

It looks like the bubbles are coming from the bottom of the nut.
So will I need to just replace part #15?
Or will I need to replace the reservoir and/or line as well?
