What this part does

The Smart Opener Control Unit is an electronic module that manages the hands-free trunk opening feature, often referred to as the kick sensor system. Mounted behind the rear bumper cover, it processes signals from the capacitive sensor antennas to detect a specific foot movement. When a valid motion is recognized, it communicates with the central body domain controller to release and power-open the trunk lid. Failure of this module typically disables the hands-free tailgate function entirely and will log a comfort access system fault in the vehicle's diagnostic memory.

Before you order

• This module requires initialization and coding using ISTA or a compatible advanced diagnostic tool to synchronize properly with the vehicle's comfort access system.
• Verify that the lower bumper sensor strips and wiring harnesses are intact. Wire corrosion or physical damage to the bumper antennas is frequently misdiagnosed as a failure of this control unit.
• Match the part number 61357451529 exactly against your original unit, as BMW utilizes several different tailgate modules depending on the specific options originally ordered on the vehicle.
• Ensure the mounting bracket on the vehicle is free of severe collision damage, as the module must be secured in the correct orientation to properly read the sensor sweeps.
