Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
CBS: Condition Based Service
CBS is not a function of the driving dynamics control. Condition Based Service means "demand-based service". Various service operations and components such as engine oil and brake pads are integrated in CBS. The remaining distances for the front and rear brake pads are calculated separately in the DSC control unit. When making the calculation, the condition of the brake pad wear sensors is taken into account (data point at 6 mm and 4 mm).
In a running production change, the 2-stage brake pad wear sensor was discontinued in the F0x and F1x, where it was replaced by a single-stage brake pad wear sensor.
