Condition Based Service (CBS)
What is CBS?
Conditional based service (CBS) is an evolution of BMWs standard service indicator system (SIA) previously fitted with across the model. It was first introduced in 2002 when the new 7 series model was launched and is now a standard feature on most new models.
Benefits of CBS
The concept of CBS was to create a flexible yet economical maintenance schedule for serviceable items fitted to a vehicle. Unlike its predecessor (SIA) which used fixed time and distance servicing schedules (days and m/km’s) the innovative CBS system goes one step further. This intelligent system constantly gathers information from modules and sensors fitted around the vehicle which allows flexible intervals to be created preventing unnecessary replacement of components which still have substantial service life left. In essence there is an aim to lengthen service intervals and maximise the use of serviceable components.
Components supported by CBS
The type of CBS components supported on a particular model will vary depending on specification and engine type.
Items fall into two main groups:
- Sensor based items
These items are monitored by physical and virtual sensors with reference being made to some variables such as vehicle mileage, driving styles and temperature. Items included in this group are:
- Engine oil- monitored by the DME/DDE engine control module
- Micro filter/pollen filter
- Front brake pads – Monitored by the DSC stability control module
- Rear brake pads – Monitored by the DSC stability control module
- Diesel Particulate filter – Monitored by the DME/DDE engine control module
2) Internally calculated items
Certain items monitored by the CBS system do not require physical sensors. These serviceable items still operate under fixed intervals with remaining service life calculated by the instrument cluster based on time and distance. Items included in this group are:
- Brake fluid
- Spark plugs
- User interface
- Instrument cluster
The instrument cluster gives advanced notification of any pending service requirements via information displayed on the LCD. This is displayed in the form on a ‘SERVICE’ warning followed by information relevant to the component requiring maintenance. BMW aim to give approximately four weeks advanced notification of any maintenance requirements to prevent drivers accidently ‘running over’ service schedules.
Further information can be accessed via the i-Drive system. By navigating through the i-Drive menu into the ‘Service Menu’, it is possible to check the current state and remaining serviceable life of all CBS monitored components. Each item will be highlighted in either Green, Yellow or Red and display a percentage value indicating remaining serviceable life.
- Green item = No service required at present
- Yellow item = Service life nearing its end
- Red item = Service deadline has been passed
