Indicator Lamp Flashes
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 indicator lamp on the left of the light switch always flashes if a fault is detected in the system.
The indicator lamp also flashes if the bi-xenon headlights are defective and the adaptive headlights are deactivated for this reason.
The light switch cluster sends the message "Dipped beam headlights on" to the AHL control unit.
The message "Dipped beam headlights on" is generated separately for each bi-xenon headlight unit.
If one of the D2-S bulbs fails, the turning movement of the adaptive headlight function is deactivated.
