A number of BMW models now feature Condition Based Service (CBS), an evolution of the innovative BMW Service Interval Indicator.
CBS works by employing sensors to constantly monitor parts subjected to wear and ascertain the extent to which servicing is necessary. This data is then saved and stored on a microchip in your remote control key. Using a KeyReader, BMW Service staff can download this information to provide an accurate analysis at any given time. This means that until such time that wears progresses to defined limits, no service or maintenance work is required.
The savings are measurable in terms of both time and outlay.
CBS is not a feature on all BMW models.
