I also have the dash lights problem (2008 convertible), and when it rains or is cold (like freezing or below), the lights come on for awhile, sometimes they stay on for my entire drive to work. So I believe the cold is contracting something to make contact, and the humidity due to the rain also causing something to make contact. I wish I could locate that contact point.
