I had a lot of fun with the front air suspension on my L322. Have you taken a read through this thread yet?: http://www.aulro.com/afvb/l322-range...ce-airbag.html and the follow-on post: http://www.aulro.com/afvb/showthread...29#post1586929
My airbags looked OK visually, but they'd go down randomly overnight.
When I took them off (a pretty easy job BTW) they looked like this at around 7 or 8 years old:

In certain positions they would hold air, and things would be ok for a day or two, then something would change and they'd sag the next day.
