Vehicle Identification Check
WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.
The information stored redundantly in the instrument cluster and the CAS control unit (Car Access System) is:
- Vehicle identification number
- Odometer reading
- CBS data
The vehicle identification number and odometer are used to prevent manipulation. CBS data are important in the service organisation (Key Reader and service acceptance module (SAM)) and must not be lost. Refer to E60, E61, E63, E64 - GENERAL INFORMATION ON INSTRUMENT CLUSTER .
