Bienvenido MFLV,
entiendo que has desmontado el faro para poner la bombilla. Comprueba que este bien conectada el cable (algun pin doblado) y si es ASI, entonces si tendras que intentar borrar fallos y hacerle un ajuste basico
Basic Setting Headlight Adjustment:
[select] [55 - Xenon Range]
[basic Settings - 04] -> Group 001 -> [Go!] Activate the Basic Setting.
[ON/OFF/Next]
The meas. block field now shows "Wait" and should switch to "Adjust Headlights" then (this may take up to 10 seconds).
Adjust the headlights using their manual adjusting screws as referenced against a suitable aiming target.
[ON/OFF/Next]
The adjustment should now be learned.
[Done, Go Back]
Don't forget to check/clear fault codes afterwards.
[Close Controller, Go Back - 06]
