Deactivation of adaptive headlights function in response to system faults

WARNING: This page is about a different car, the 2008 BMW 760Li, 2007 BMW 760Li, 2006 BMW 760i, 2006 BMW 760Li, and 2005 BMW 760i. However, it is still accessible from the selected car via links, so may be relevant.

Until 09/2007, a system fault will be indicated by the indicator lamp on the light switch flashing.

From 09/2007 system fault will be indicated by a Check-Control message in the instrument cluster.

Dazzling of oncoming traffic must be prevented in the event of a system fault.

For this reason, the adaptive headlights function is deactivated as follows:

If the stepper motors are still functional, the headlights are returned to the straight-ahead position. The headlights are no longer moved towards bends in the road.
If it is no longer possible for a headlight to be moved back to the straight-ahead position, the headlight is tilted downwards (by the stepped motors for automatic headlight-range adjustment). This prevents dazzling of oncoming traffic.
Vehicles up to 09/2007

If the headlight cannot be tilted downwards, the bi-xenon bulb in this headlight is disabled as follows:

When the vehicle is parked up, the control unit registers sleep mode for the adaptive headlights, as follows: Vehicle standstill and terminal R OFF for several minutes.

The next time the vehicle is restarted, the bi-xenon light of the defective headlight is not switched on.

The front foglights are switched on in order to ensure a minimum level of illumination.

The dipped beam headlights are not switched off while the vehicle is in motion.

NOTE: From 09/2007, the dipped-beam headlights will not be switched off in the event of a system fault.

If a system fault develops in the adaptive headlights, the dipped-beam headlights for the affected headlight will not be switched off.
