How It Works

WARNING: This page does not describe the selected car, but rather 37 other vehicles, including the 2006 BMW 330Ci, 2006 BMW 325Ci, 2005 BMW M3, 2005 BMW 330xi, and 2005 BMW 330i. However, it is still accessible from the selected car via links, so may be relevant.

The AHL control unit uses dynamic driving data to calculate the movements of the adaptive headlights and the automatic headlight-range adjustment.

The AHL control unit must be coded with the vehicle-specific data.

Vehicle-specific data includes, for example:

Wheelbase
Height of headlights
Data for the headlight headlight-range adjustment (characteristic curve)

Data specific to the headlights is coded in the SMC (stepper motor controller).
