E89 Z4 (2009 - current)
Shame on me. My 2005 Z4 2.5, 70K miles got rained into. It was short and heavy, perhaps 5 minutes. I quickly wiped the interior. Started with no issue, except: the airbag warning light came on. Clearly caused by the rainin. Do I really have an airbag issue ? How to diagnose and/or fix ? Thanks...
