Luminous range control

Hello, someone can tell me where the actuators for the headlight adjustment are to be found at the V40 (Bj. 12/98). Supposedly (according to Volvo workshop) both should be defective at my car; when I wanted to find out about repair in a free workshop today, the mechanic looked up and found that there is no actuator or similar installed on the headlight. For comparison he also showed me the changed headlights of a 440, which he repaired the week before. Only the two mechanical adjustment options per headlight were available with my V40. Could this be due to the level control or is it possible that the adjustment option is accommodated elsewhere? Or should the Volvo workshop possibly have put me on my arm? Thanks for information, greetings, geo
