The top video sounds normal ish to me. The ticking you hear is due to the high pressure of the fuel injectors. The bottom video (cold start (1)) sounds odd though as mine goes quiet after the engine goes back to idle speed. It could be the microphone exaggerating the sound on our side. Does it sound exactly the same in person?

It's very difficult to diagnose a noise from a video unfortunately. I'm not sure about vanos issues on the f10. I know the e39 and the e60 both had vanos issues. The only thing I can tell you is that mine has a similar noise on cold start and it's a ticking of the injectors.

If it's better now then you may have had a poor quality oil in it before or it was just worn, the LM is a good lubricant in the right grade and quite a few US forum members say they use it.
