For ease of selection, the part features a dedicated OEM number and associated interchangeable numbers, allowing for technical verification of compatibility with specific equipment versions. It is advisable to compare the markings with the service documentation or the removed part before purchase to ensure full compatibility with your BMW's safety system.
