Audi Q2 GA Headlights Leveling Lamp Height Sensor Front Headlamp Unit 5Q0907503

Audi Q2 GA Headlights Leveling Lamp Height Sensor Front Headlamp Unit is an original component of the headlight height adjustment system used in Volkswagen group vehicles. It is responsible for precisely transmitting information about the body position to the headlight control unit, which allows for maintaining the correct road illumination line and improves driving safety when the vehicle's load changes.

Purpose and function in the vehicle

The presented sensor is a component mounted in the front suspension area, where it monitors the change in body position relative to the axle. Based on its signal, the headlight control system adjusts the height of the light beam, reducing the risk of dazzling other road users and improving visibility in front of the vehicle.

This type of solution is particularly important in cars equipped with automatic headlight height adjustment, where a stable and repeatable reading from the sensor has a direct impact on comfort and safety when driving at night.

Construction and technical properties

The Audi Q2 GA Headlights Leveling Lamp Height Sensor Front Headlamp Unit is a factory component from the Volkswagen group, designed to work with the vehicle's original electrical system. The design includes a body integrated with an arm that works with the suspension, which enables accurate reproduction of body movement in the form of an electrical signal.

Key features of this component include:

• dedicated design for operation in the front part of the vehicle,
• compatibility with the factory headlight height adjustment system,
• OEM-designed electrical connector, facilitating installation in the vehicle's wiring,
• construction adapted to work in conditions exposed to moisture, dirt, and temperature changes.

Condition of the component and benefits of using OEM parts

The offered sensor is a used original part, sourced from dismantling, which allows for maintaining factory fitment to the suspension system and the vehicle's electrical installation. Using an OEM part instead of a damaged or unstable sensor reduces the risk of errors in the lighting system and problems with technical inspections.

Choosing an original component from the Volkswagen group also means:

• maintaining compliance with the factory operating parameters of the lighting system,
• easier diagnostics in case of potential faults,
• certainty of proper mechanical and electrical fitment.

Application in service practice

Replacing the headlight leveling sensor is recommended in situations where errors appear in the lighting system, the automatic height adjustment works unstably, or there is visible mechanical damage to the component near the suspension. Installation involves mechanically mounting the sensor in the front part of the vehicle and connecting it to the electrical system, followed by – if necessary – performing an adaptation in the headlight control unit in accordance with the service procedure.

If you are planning a comprehensive repair or upgrade of the front lighting area in your Audi or another model from the Volkswagen group and need other elements from the same group, such as sensors, control modules, or wiring harnesses, check the available parts in the Other Volkswagen category.
