• consistency with factory comfort access features for the trunk,
• reducing the risk of electronic diagnostic errors.

Before installation, it is recommended to verify compatibility by OEM number and vehicle equipment configuration to ensure seamless integration with the existing system.

Component Characteristics and Installation

The offered module belongs to the Electronic Control Modules and Controllers group, meaning it is designed to operate within the vehicle's controller network and requires proper connection to the factory wiring harness. Depending on the car's configuration, installation may involve:

• removing trunk trim panels to access the controller,
• replacing the module in its existing mounting bracket,
• potential adaptation or coding using an appropriate diagnostic tester.

Due to the nature of an electronic component, installation by a workshop experienced with Mercedes electronics and diagnostic tools is recommended.
