The intelligent maintenance system CBS permanently monitors oil levels and the degree of wear and tear on individual components. It also checks the time/mileage recommendations for fixed services. It analyses this data and tells you when a service is next due.
Data can be checked at a glance on your Info Display, which automatically gives you four weeks' notice. The iDrive Control Display gives you an exact information on which component needs a check. So you can plan your service appointments well in advance and avoid any unnecessary maintenance work.
