The second most common possibility of a cabin noise in your BMW 5 Series is that some components that come apart may be loose, either because of too frequent disassembly that would have reduced the holding between these elements, or because of vibrations.

It is difficult to resolve this problem, you can always look for the exact source of the noise, and try to put foams or tape between the expanding units to limit their noise from their expansion.
