Anyone really Mountain man, nobody has posted about having the knuckle replaced yet and whether it works, I have been told it isn't available for the 43 or 63, but someone posted they were having them replaced on there 63 on the 27th December but haven't posted since.
To clarify MB have never admitted it as a fault, just a characteristic. Even the motoring ombudsman didn't find it as a fault when I went to them but as MB offered me a set of wheels with winter tyres advised that I accept that and I did.
