Purpose and function in the vehicle

The presented sensor is designed for installation on the left side of the vehicle, i.e., the driver's side. It works with the lane change warning system, analyzing the situation in the blind spot and adjacent lanes. A properly functioning module of this type:

• supports the driver in safe lane changes,
• enables the correct operation of warning signals in the mirror or on the dashboard,
• communicates with other body control units via the vehicle's bus system.

By maintaining the original BMW architecture, the module is prepared for operation in post-facelift (LCI) F-series vehicles, which promotes stable communication with other safety systems.

Benefits of using an original BMW module

Choosing an original BMW lane change warning sensor ensures consistency with factory electronics and minimizes the risk of software compatibility issues. The module from this group:

• maintains the factory operating parameters of the warning system,
• is adapted to the specific configuration of post-facelift F01, F06, F10, F13 models,
• facilitates diagnostics using standard BMW service tools.

The used component allows for an economical repair of the driver assistance system while maintaining a high level of safety and driving comfort.

Condition, installation, and selection by part number

The offered sensor comes from dismantling and is classified as a used original BMW part. Before installation, a standard service procedure is recommended, including:

• verification of compatibility by OEM number and interchangeable numbers,
• checking the placement on the vehicle (left side),
• potential adaptation or coding in the vehicle after installation.

To minimize the risk of incompatibility, it is worth using the part number from the existing module or data from the vehicle's service documentation.
