What are the common causes for the AC not working in a 2012 BMW Alpina B7 xDrive?

When your 2012 BMW Alpina B7 xDrive's air conditioning system fails to cool, it can be frustrating, but understanding the common causes can help you diagnose the problem. One prevalent issue is a refrigerant leak, which can significantly reduce the system's efficiency and is often the first thing to check.
