What this part does
The Blind Spot Sensor is a short-range radar unit mounted behind the rear bumper cover on the corners of the vehicle. It monitors the adjacent lanes for approaching traffic, communicating with the body control network to trigger a warning indicator in the side mirror if a vehicle enters the driver's blind spot. When this module fails, whether from water intrusion, internal fault, or a rear-end collision, the active lane change warning system is disabled, and a driver assistance error message will appear on the central display.

Before you order
Verify that the part number on your original module matches 66326881203 exactly before purchasing, as BMW uses different radar frequencies and communication protocols depending on the exact driver assistance package. This module will require initialization and coding to the vehicle using ISTA or a high-end diagnostic scanner before it will function. Ensure that your bumper mounting bracket is perfectly straight, as radar units are highly sensitive to physical alignment, and a bent bracket will cause calibration failures.
