A6 (4B) Xenon adjustment


Recommended Posts

Tried to adjust the headlights on my 2002 A6 with the procedure from Ross-Tech wiki.


In CarPort I selected the ECU 55 Vertical Headlight aim control, went to Basic Settings -> block no. 1 -> Basic Settings. Then the lights moved into zero position, ready to adjust. After I've manually adjusted them, I went to block no. 2 to let the ECU store the settings, but nothing happened...


Got this fault on the ECU: 01539 Headlights were not adjusted


Tried to clear the fault, but it came back instantly. Have tried to go through the procedure several times, but no luck :-(
