SERVICE INFORMATION

This Service Information Bulletin (Revision 4) replaces SI B00 07 02 dated June 2024 .

What's New:

Procedure revised
Attachment 4 added-KeyReader and Digital Key Card Identification

SITUATION

The BMW in-vehicle maintenance reminder system provides the vehicle operator required service "due" notifications, and together with the applicable periodic inspections, it helps support maintaining the road safety and the operational reliability of the vehicle.

The CBS system determines the maintenance recommendation using sensors and special algorithms that consider the operating conditions of the vehicle. The system makes it possible to adapt the maintenance measures to your user profile.

The CBS maintenance system monitors the maintenance requirements of the vehicle. Fixed service intervals are no longer necessary since CBS analyzes the actual service requirements and informs the driver when they become necessary.

CBS monitors inputs such as driven miles, fuel consumption and/or time to determines the required maintenance of several service items independently of each other. This technology prompts the customer to bring his/her vehicle in for service whenever one of the CBS items requires maintenance and/or replacement

CAUSE

The goal of CBS is to strike a compromise between two frequent maintenance intervals and two rigid service intervals that call for the replacement of some maintenance items that may still have a substantial service life remaining.

CBS also indicates when service is due, overdue, and continues to recommend maintenance task(s) during and after the BMW Ultimate Care or BMW Maintenance Program Agreements

CORRECTION

This information is intended to provide a general system overview of CBS, which is an advanced development of the previous Service Interval Indicator systems.

PROCEDURE

For details of CBS service items and maintenance intervals, refer to the vehicle and model year-specific Service Information bulletins entitled "New Vehicle Preparation and Maintenance Requirements" located in Group 00 or the relevant vehicles Owner's Manual.

SERVICE RECOGNITION

The vehicle recognizes when service is required using the following methods:

Adaptive
By using sensor technology and algorithms, the vehicle can determine the required maintenance of a service item depending upon the individual customers driving style. For example:
1. Oil Change Interval - Determined from a combination of the engine oil condition sensor which monitors the oil condition, oil level, and oil temperature, and from additional algorithms using these parameters: engine load, fuel consumption, idle time, and distance since the last oil change.
2. Microfilter Replacement - Every second engine oil service, unless otherwise noted.
3. Remote control transmitter battery replacements - Every second engine oil service, unless otherwise noted (refer to SI B01 01 13 )
4. Front and Rear Brake Pad Replacement - Determined from brake lining wear sensors located directly on the brake pads, and in some vehicles, from residual wear algorithms which use travel distance, wheel speed, braking pressure, braking time, and braking frequency to calculate wear.
Fixed Time (months)
Calendar days/months are used to determine the required maintenance of certain service items. For example:
1. Brake Fluid changes - After the first 3 years, every 2 years after that.
2. State Safety and Emissions Inspections.
Fixed Distance (miles)
Travelled mileage is still used to determine the required maintenance of certain service items. For example:
1. Vehicle Check
2. Spark Plug Replacement - Dependent on vehicle model and CBS version
3. State Safety and Emissions inspections
Connected to Oil Service
Some service items may be due after multiple oil services. Based on oil service is being performed, certain additional service items may also be due. For example, engine air filter replacement may be due every second oil service. These are measured by the Service Counter for the oil service.
1. Engine Air Filter Replacement
2. Spark Plug Replacement - Dependent on vehicle model and CBS version
3. Microfilter Replacement - Dependent on vehicle model and CBS version

SERVICE INTERVAL INDICATOR

Determining the CBS

To determine the required service work due, the employee has several options:

Instrument cluster (aka "KOMBI")
Central information display (CID)
Aftersales Workplace (AWP)
Aftersales Information Research (AIR)

Inside the vehicle - Service indicators are displayed in two possible locations.
1. Instrument Cluster (aka "Kombi") - The next due CBS item, or any overdue CBS items will be displayed in the instrument cluster briefly after initial start-up. The Instrument Cluster CBS display may use different icons or text:
  - A colored symbol representing the CBS item and its wear in the center lower display:
    - Orange or Green for no service due
    - Yellow for service due
    - Red for service overdue
  - The remaining distance or time till the next CBS item is due, displayed in the center lower display.
2. Central Information Display (CID) - For vehicles with a CID, the CID can display all information on the individual CDS items (i.e., service status, mileage until due, time until due). The CBS functions are stored in the "Settings" menu and can be viewed at any time.
Outside the vehicle - Service indicators are displayed in three possible locations.
1. Workshop information system (ISTA)
  It is always recommended to reset the CBS jobs via the diagnosis system. It is only possible to code the statutory intervals specific to individual countries or states with the diagnosis system. CBS Data can be read or reset through ISTA using the following test plans:
  - "UDS CBS Reset" - ABL-WAR-AS6100_CBS_RESET
    The CBS Reset test plan can be used to perform a reset of any CBS item wear data back to 100%. Each time the item is reset, the Service Counter will increase by 1.
  - "CBS vehicle data correction" - ABL-WAR-AS6100_CBS_KORR
    This test plan is used to correct CBS data stored in the vehicle. CBS data can be incorrect due to accidental CBS resets or data corruption from faulty programming. The following values can be reset for most CBS items:
    - Percentage of wear
    - Forecast of wear
    - Service Counter
  - "CBS correction, tester data" - ABL-WAR-AS6100_TESTER_KORR
    This test plan is used to change CBS relevant values stored in the ISTA machine itself, such as time, date, and service phone numbers.
2. Aftersales Workplace (AWP)
  Service planning allows you to view the vehicle's condition-based service requirements, add service shares to your service process data and add the service to the vehicle's service history.
  - Vehicle histories - exhibits the most recent stored CBS KeyRead data
  - Lead & Demand Overview - can display 3 types of CBS source data:
    - Over-the-air, Remote Key Read (RKR)
    - Key data, KeyReader
    - Vehicle master data
  NOTE: More information about the usage of AWP can be found in S-GATE (Dealer Universal Portal) under the USER Guide tab.
3. Aftersales Information Research (AIR)
  An information research system in the Aftersales area that maps technical service data in a single system.
  - Vehicle histories - presents the most recent stored CBS KeyRead data.

KEYREADER AND ID TRANSMITTER

CBS information about the vehicles maintenance and fault codes are transferred during vehicle operation to the ID transmitter. The stored information can be retrieved by performing a key read via the KeyReader. After the data is backed up to the key pool (KAI) it is then available for evaluation in AWP, AIR, or other local systems in your BMW center.

In some cases, the data stored in the key may be outdated and contradict the current vehicle information taken during service acceptance. Typically, this occurs when the spare key is being used. Since the spare key is not regularly used to operate the vehicle, the key data, including the vehicle mileage and maintenance status, may not be current.

During a vehicle write-up, every effort should be made to read the most regularly used key for the vehicle, not a spare or secondary key. In the circumstances where key data is outdated or not current, perform a manual key update and read out the key data again to obtain the most current vehicle information.

NOTE: Earlier vehicles only provide the mileage and VIN, newer vehicles (E6X and E9X onward) can provide further information.
