Function and Application of the Ultrasonic Module

The ultrasonic alarm module in Mini R55 and R56 models is responsible for monitoring the passenger compartment using ultrasonic waves. When the alarm is armed, it monitors changes in air volume inside the cabin, reacting to:

• opening doors or windows from the inside,
• attempts to interfere with the passenger space,
• movement in the cabin after a window is broken.

This ensures the alarm system remains fully effective even in situations where standard perimeter sensors may not be sufficient. Using an original module allows for proper cooperation with the central locking, siren, and comfort controller.

Compatibility and Integration with Mini Electronics

The offered Mini Ultrasonic Alarm Module is designed for R55/R56 family vehicles that are factory-equipped with interior sensors. The component works with the original electrical system, enabling:

• preservation of factory alarm functions without additional wiring modifications,
• correct communication with the security system's control unit,
• maintenance of consistent operation with other comfort modules.

The presence of the OEM part number and available replacement numbers in the technical specifications facilitates verification of compatibility with the specific vehicle equipment version and production year.

Component Characteristics and Product Condition

The module belongs to the Other category, meaning it is a specialized security system component that is not part of standard operational groups. The product is offered as a used item, which in practice means:

• preservation of the original design and operating parameters intended by the manufacturer,
• possibility of installation as a replacement for a factory-installed module,
• attractive cost-to-functionality ratio compared to new components.

For users who want to restore full alarm functionality after interior sensor failure, this is a cost-effective solution that maintains the system's factory operating logic.

Benefits of Using an Original Mini Module

Using an original ultrasonic module in the Mini R55/R56 offers a range of practical benefits:

• Full integration with the alarm system – no need to adapt universal sensors that may generate errors or false alarms.
• Stable operation in operating conditions – the module is designed for the specific interior architecture and vehicle electronics.
• Restoration of factory functionality – restoring interior monitoring after damage to the original component.

This is a particularly beneficial solution for workshops specializing in the Mini brand and for users who care about maintaining the original vehicle configuration, allowing them to avoid compromises in safety.
