WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2006 BMW Z4, 2006 BMW M3, 2006 BMW M Roadster, 2006 BMW M Coupe, and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle order is stored in the CAS. The vehicle order describes the vehicle model, the national version and the items of optional equipment.
The following data is stored in the CAS redundantly with the instrument cluster:
- Vehicle identification number
- Odometer reading
- Data for Condition Based Service CBS)
The vehicle identification number and odometer are used to prevent manipulation. The CBS data is vital for regular maintenance during after-sales and must not be lost.
CBS data are updated in the vehicle key or remote control within a driving cycle.
A driving cycle is defined by:
- First updating carried out when:
- Terminal 15 ON and
- Speed above 50 km/h at least once and
- Speed fallen back to below 30 km/h
- The data is updated again when:
- Distance driven exceeds 10 km and
- Speed above 50 km/h at least once and
- Speed fallen back to below 30 km/h
In addition, a concealed service function can be used to update the CBS data on the ignition key or remote control:
- Insert ignition key -> Press and hold down central locking button -> Switch terminal 15 on
