Redundant Data Storage

The CAS is one of three control units in the E65 to store important vehicle specific data.

The CAS is responsible for storing:

• The full 17 digit VIN Number (Only the last 7 digits are stored in codeable modules)
• Vehicle Order (FA)
• Total mileage
• CBS (Conditioned Based Service) Data

Redundantly, the full 17 digit VIN and the Vehicle Order (FA) are stored in the LM and the mileage is stored in the KOMBI. CBS data is stored in the Remote Controls.
