All models with Condition Based Service
SITUATION
This information is intended to provide a general system overview of Condition Based Service (CBS), which is an advanced development of the previous Service Interval Indicator systems.
CBS measures, monitors and determines the required maintenance of several service items independently of each other. This technology prompts the customer to bring the vehicle in for service whenever one of the CBS items requires maintenance or replacement. CBS strikes a compromise between too frequent maintenance intervals and too rigid service intervals that call for the replacement of service items that may still have substantial remaining useful life. CBS also details the recommended, due, and overdue required maintenance during and after the BMW Vehicle Maintenance Program Agreement.
For details of CBS service items and maintenance intervals, refer to the relevant vehicle Owner's Manual.
