Never could identify the source... but it never caused a problem (that I know of)

Sorry to bump this old thread, but I am looking at buying a used 335xi - n54 engine, and it's producing the same noise. Anyone ever confirm what this was, or have better insight now? Thanks!

The noise is coming from the boost solenoids. I would replace both. They aren't too expensive and are easy to do.
