I had a similar problem with my 2004 3.0 which was identified by BMW as being caused by a dirty connector in the battery compartment in the trunk. The line resistance caused by the dirty connector caused the fault code and the resultant dash display light. For what ever reason the wiring harness has a connector in that area that interfaces with the airbags. The technician metered the wiring and identified a voltage as being out of parameters. He cleaned the connection and I haven't had a problem since. It may not be the cause of your problem but it does illustrate how a seemingly unconnected problem can cause error codes elsewhere.
