Understanding Condition Based Service (CBS)

BMW 1-Series

CBS is the latest maintenance tracking system BMW and MINI created to manage maintenance items and regular service intervals. Where service intervals and maintenance items used to be based on mileage or time (and a series of green, yellow and red lights on the instrument cluster), sensors now monitor fluids and systems to determine replacement based on how the vehicle is driven.

This information is accessible via either the iDrive monitor or the dashboard information center. A mileage figure or date is shown indicating the date or mileage at which time the service will be due. A negative number indicates how many miles overdue the specific service may be.

The CBS system is checked during every service here at Pacific Motorsports, so all parties are aware of the current conditions that the vehicle is reporting. This modern reporting system is not the be-all-and-end-all, however, it is but one element in BMW and MINI’s comprehensive factory recommended maintenance program, which, when followed will extend the longevity and enjoyment of your already well-built car.
