The dipped headlamps adjustment button in the exterior lights control panel sends the command directly to the Instrument Panel Node (NQS) which controls the actuator motors sending appropriate voltage signals.

one lamp comes on normally but does not carry out the vertical adjustment and remains fixed in the middle position

The left or right adjustment cannot be carried out with the dipped headlamps on
