2019 C63S Knocking Noise - Normal?
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

TIA
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
)
