Question 2019 C63S Knocking Noise - Normal?

Evening all,
I've noticed my car has a weird sort of 'knocking' noise coming from the passenger side (UK - RHD model) I've had it a few times in the past, but didn't think much of it as it went away.
However in the past month it's been occurring frequently, it's at a point now where the noise is basically there all the time once the engine has been running for a few minutes.
I've not noticed any issues with performance; it's still running perfectly fine, but I'm a bit concerned it might be a precursor to something expensive

YouTube clip
Would anyone mind having a quick listen and let me know if it's something they recognise, and if I need to worry about it, please?

TIA

Oil level looks normal, just under the max line on the dipstick.
it's gone into Mercedes for a service today, so I've mentioned the noise - see if I'm lucky and they identify it. (not holding my breath though )

Hi mate,

I have exactly the same issue on mine. Did you figure out what the issue was?

Many thanks!
