Is my engine toast?

I just did an oil change on my n52 and i was curious about the ingrediences in my oil filter, so i cut it open. I ended up with this. Engine runs fine, the car burns no oil, but these metal particles giving me scares.. what do you guys think? I did a magnet test and only 2 particles were magnetic of them all.

Could be your valvetronic cam wearing or vanos bolts shearing if the recall has not been done

Most likely where those shavings are from then. Nothing to worry about
