The brake life service estimator in iDrive is generated by driving style not actual pad wear. The sensor is there as a failsafe so if the computer calculated wrong you'll wear the tip of the sensor off tripping the "you need to change your brake pads now" light.

This is not the case on the newer F series cars. On the E series it was a simple trip sensor, but on the F series they started using a resistive sensor that measure pad thickness under 2 or 3mm remaining pad life. If the sensor starts to get worn at all it needs to be replaced now or the pad service indicator will not be able to be reset. |
Do you have the technical documentation as source for this?
