Twingo Headlight Range Control Fault

I've got a 2020 Renault Twingo Electric with 117077 km. The headlight range control is faulty. Error memory logged it, and the speedometer warning light is on. The low beams shine too low or too high, making night driving hazardous. I suspect a defective servomotor, but I'm hesitant to start repairs without more info. Has anyone else had similar lighting system issues? Any guidance before I visit the repair shop?

Heard about this before. The adaptive headlight system uses sensors to adjust the beam. If a sensor goes bad, gets dirty, or the control module hiccups, it throws everything off. Have you checked the electrical connectors to the headlights? Sometimes a loose connection causes weird problems.

Could you tell me where the electrical connectors are? A detailed description or image would help my inspection. What signs should I look for, like corrosion or displacement?

The connectors are at the back of the headlight unit. Pop the hood and remove any plastic covers to get a clear view. Look for anything loose, corroded (green/white powdery stuff), or damaged. With it affecting both headlights and the error code, it sounds like the servomotor or the system that levels the light. Without proper diagnostic equipment, I'd recommend a workshop.

Your servomotor suspicion was right. The repair required replacing the component, costing 1040€. It's resolved, and the car is safe for night driving. Your insights guided me to the right action. Thanks for the help.
