Need Help: M3 normal noise or vanos issue?

Hey everyone, just looking for some input about whether or not my M3 is making regular noises or if I have something to worry about.

The car is super quiet at idle, has no lights on the dash, gets normal gas mileage and pulls smoothly throughout the rev range. I just got the car about a month ago, so its tough to say whether any decrease in power is real or just me getting used to the car--even if it is a real decrease in power it isn't anything super noticeable as the car still pulls pretty strongly as compared to my limited experience with it so far. The car has 80,000km on it.

Sorry for the crappy vid quality, but using the M symbol as a guide the camera is placed mostly near the vanos unit, then briefly along the left hand side of the engine and then back over to the right where the injectors are. The engine was around 3-4k rpm.

The car is in need of a valve adjustment, so I thought the sounds at 3 or 4k rpm were due to loud valves, but let me know what you think and thanks for your help.
