Purpose and function of the cover

The described cover is dedicated to Mercedes models from the W202 and C208 series, where the alarm system motion sensor is located in the rear part of the headliner. The component is responsible for the stable mounting of the sensor and its discreet concealment, which reduces the risk of accidental damage and contributes to the proper operation of the vehicle's security system.

The placement in the rear area of the vehicle promotes even coverage of the passenger compartment by the sensor, and the properly designed geometry of the cover helps maintain the correct detection field without unwanted obstructions or mounting gaps.

Color scheme and interior integration

The grey color of the cover has been selected to harmonize with typical headliner finishes in Mercedes W202 and C208 models. As a result, the element does not visually stand out from other upholstery parts, which allows for maintaining a consistent, factory-like character of the cabin.

The neutral, subdued color facilitates easy integration with both lighter and darker interior variants, and the appropriate shape of the cover allows for precise fitting to the headliner contours, minimizing the risk of gaps or unsightly deformations.

Mounting characteristics

The roof alarm motion sensor cover has been designed as a component matched to the factory mounting points in the rear of the vehicle. The appropriate geometry of the mounts facilitates installation and removal during service work on the alarm system, without the need to interfere with the headliner structure.

This solution is particularly useful when replacing a damaged cover, repairing the alarm installation, or during interior renovation, when the priority is to maintain the original layout of elements and the proper operation of the motion sensor.

Condition and vehicle application

The item is offered as a used part, which allows for an economical replacement of a damaged or missing cover while maintaining compliance with the factory interior design. For owners of Mercedes W202 and C208 models, this is a practical solution when the priority is to restore the full functionality of the alarm system and the aesthetics of the headliner without having to resort to replacements with uncertain fitment.

The cover will work well both in vehicles used on a daily basis and in units undergoing gradual renovation, where maintaining original design solutions and visual consistency of the interior is important.
