Purpose and function of the MULF module

The presented Bluetooth controller has been designed as an element of BMW's factory electronic architecture, responsible for handling wireless communication in E81, E87, and E90 series vehicles. As a control module, it works with the MOST/infotainment installation, enabling phone integration with the car's system, hands-free kit operation, and data transfer in accordance with the specific vehicle's equipment configuration.

Thanks to the use of a dedicated MULF Bluetooth controller, the driver gains convenient access to phone functions via factory buttons and the iDrive interface, without the need for additional external adapters.

Compatibility and part identification

The module belongs to the BMW OE group, which means it is a component compliant with the manufacturer's factory standards. Identification is performed via the OEM part number and an extensive list of interchangeable numbers, making it easy to match the controller to a specific vehicle configuration. The presence of multiple reference numbers allows this module to be used as a replacement in various equipment versions, provided the catalog designations match.

Before purchasing, it is recommended to compare the OEM part number or interchangeable numbers with the data in the vehicle and service documentation. This facilitates the selection of the correct controller and minimizes the risk of incompatibility with the electrical installation and the car's software.
