Changing auto level motor on xenon headlight

Hello. I was just wondering if anyone have tried to change the auto level motor inside the headlamp housing? My left side (drivers side in norway) auto dip lives its own life, sometimes working and sometimes not, so i thought i should try changing the motor before i use alot of money to change the whole thing. The reason i suspect its the motor, is because when it decides to work, it makes alot more noise than the other one.  So is there any exploded view of the whole housing somewhere, or a drawing of how to change the motor, or can someone explain a little bit? thanks on forehand
