2013 F20 118i Engine Noise

[BmComplex]

For the last few days, I’ve been experiencing a strange engine noise. For the life in me, a cannot figure out what it is.



For ease of trying to explain something, I don’t understand I thought I’d share a short video clip.

Things I have checked:

Oil and fluid levels topped up

Look for any major oil leaks (there is a small leak on the top of the turbo)

All comments are greatly appreciated.

Perhaps the timing chain? Check if the noise is coming from the timing chain area.

Hmm it turned out it was the timing chain, thank you @RedlineRacer for your input.
