Automatic low beam switched on in bright conditions
E39, E46, E53, E65, E66, E85, R50, R53 with rain sensor and automatic low beam
control (option 521)
Complaint:
When "automatic low beam control" is activated, the dipped headlights come on
unnecessarily, or switch off late (in the judgment of the customer) in bright conditions. This
may happen in particular in bright, sunny weather (cloudless skies).
Cause:
Due to the design of the system, it is not possible for the low beam sensor to reproduce
human perception of the light conditions in all situations.
To ensure that the dipped headlights are switched on reliably at the onset of twilight, a
sensitive configuration of the low beam sensor has been selected at the factory. This can
cause the dipped headlights, by human perception, to switch on too early or off too late in
bright conditions.
There is no fault in the low beam sensor. A replacement of the part would not change the
situation and must therefore not be performed.
