Base Onboard Computer

On vehicles equipped with a Basic Cluster (Kombi) the Onboard computer display in the MID is not used, rather the Onboard Computer information is displayed in the instrument cluster center LCD display.

The functions of the base Onboard Computer are more limited than those vehicles equipped with a high version cluster ( IKE).

The four functions are shown below. Time and date are displayed are displayed in the MID on E39/E53 vehicles, and in the cluster in the E46

To scroll through the functions the "BC" button of the turn signal lever is briefly pressed.

Two of the displays, "Average fuel consumption" and "Average speed" can be reset to start a new calculation. To reset, press and hold the BC button for longer than one second when the function is called up. The onboard computer will then erase the previous display and start to compute a new average value.
