Is a new strut assembly inevitable?

The strut and air bag are one part, so you can't just replace the air bag. It's probably not much more work than replacing a regular strut though, other than the air line fitting going to the bag. Tischer BMW has them for about $675 or so.

My RF had a slow leak and you could spray soapy water on the lower part of the bag and see it bubbling. It was a slow leak and would be completely flat after a few hours.
