Condition Based Service (CBS) was first introduced with the BMW 7 Series and is an evolution of the service interval indicator that has featured on other models in the BMW range.

All current models are equipped with the CBS system except for X3 and Z4.

The CBS system is at the forefront of service innovation, and for this reason we want to ensure that you understand its principles and benefits.

CBS - how it works...

CBS employs sensors to monitor the condition of worn parts and to ascertain the extent to which servicing is necessary.
A microchip in the vehicle's remote control in the key saves the data along with other general information such as the odometer reading and the vehicle identification number.
BMW Service uses a device known as a Key Reader to download this information from the vehicle's key.

Maintenance is not necessary until such times as wear progresses to defined limits. This flexibility in defining maintenance intervals and the scope of maintenance work required means that only those components that the sensors show to be due for maintenance are serviced. In essence, this system allows each service to be tailored to the requirements of each and every BMW.
