BMW E46 Z3 alarm sensor bracket | MINI R50 R53, 51448243666
This is an upper alarm sensor bracket for the interior security system of BMW and MINI vehicles, replacing OEM 51448243666.
Description
The bracket secures the alarm control unit, also known as the ultrasonic module. It mounts directly into the headliner of the vehicle.
Over time, original plastic brackets become brittle and fail, causing the alarm sensor to detach or rattle. This replacement restores the factory mounting point. Additional cross-reference part numbers include 51440141043, 1999 2005, and 2000 2006.
Common Symptoms of Failure
