17-19 Mercedes-Benz W247 B-Class Passenger Seat Control Module A2479003814 OEM

Item Description
Genuine OEM Mercedes-Benz Passenger Seat Control Module designed for vehicles built on the W247 / MFA2 platform. This electronic control unit manages the power seat adjustment functions for the front passenger seat, controlling seat motors and communicating with the vehicle’s electronic systems.

The module processes signals from the seat adjustment switches and operates components such as seat forward/backward movement, seat height adjustment, backrest angle, and lumbar support. In vehicles equipped with memory seats, the module also works with the vehicle’s control systems to store and recall seat positions.

The OEM part number A2479003814 must match the original unit to ensure proper compatibility and functionality.
