Ideally you need have the vehicle's fault code memories read to determine the exact cause of the self leveling warning light as it could be anything from a failed sensor to a burst suspension airbag. But, I do recall on earlier X5 a BMW technical bulletin was released stating that a software update of the light control module (where the vehicle's ride height info analyzed) would rectify this issue. Your dealer could confirm this for you after reading the fault codes.

The thing is though, you need someone who has a MAC scanner or Snap-on scanner that can access this.
