So this is what happens when you read M5Board too much. Got it up on a lift at a shop by my house and we thought it may have been an exhaust manifold gasket. I took it to the guy who worked on my old M5 a bunch -- he figured out that it was a spark plug somewhat loose in there. Tightened it up and the sound went away! Not an expensive problem at all, haha.
@Hoodrichbiatch Thanks. Tried that out -- it doesn't stop. It sounds more like it's coming from the back and down low in the motor, not from the VANOS units. But we'll see soon.
thanks you for your video. my car mad the same sound. so today i check my spark plugs.
i found two loss spark plugs. then i tighten them. then no more taking sound ;-)

How's the car running now?
You say it was just the spark plugs?

@ANiMOSiTYZA Yeah it was just one loose spark plug. I've put on probably about 8,000 miles without any issues.

It's not VANOS..
If it was VANOS, you'd hear it when the camera was at the top of the engine.
It *could* be the start of a rod bearing going bad.. but *if* it is, then youve caught it VERY early and your chances are that the crank is fine.
However.. Rod Bearing noises are usually deeper than that.
This sounds more like a tapping than a knocking. Rod Bearing knock is a deep, heavy sound.
It could be an exhaust manifold leak; or a cam lobe; or a bad hydraulic lifter.
But get it checked soon!

PUSH THE CLUTCH PEDAL IN IF IT STOPS THEN ITS YOUR TRANNY BUT IT SOUNDS TO ME LIKE THE VANOS SYSTEM IS GOING BAD.
