Not sure if you ever figured it out, or have dealt with it. But I know for sure it's the vacuum pump. The video you put up saves me from having to put my own video up

I never figured it out.
Perhaps it IS a vacuum pump,
I clocked another 30K miles with this clapping noise, at 97,776 as of yesterday.
I am waiting for harmonic balancer to give up: then will do HB, belts, tensiner, vacuum lines and pump in one shot
I also got myself 335d with 131K miles last year.
Interesting fact - the very same M57Y engine is super quiet in E90 and sounds like a tractor in E70
