Sorry, that was a typo it was supposed to say 5.9kW. I have tried different charging stations and it’s the same result. Is there any setting I can change or a factory setting that can be applied? According to my calculations, it’s is currently take 2-3 hrs longer at a level 2 charger. And home charger even longer.
I don't think its an issue with the car, likely with the charger. The Mercedes supplied Level 1 charger is complete rubbish - mine is limited to 1.7KW, and yes it takes days to to get it from 20-80%. Are you able to configure the peak charging current of your Level 2 charger? My installer used the EVBox Install software to configure the peak charging current of my Mercedes Level 2 charger:
 
So, I am speculating here about this being a charger issue and not a car issue, but here is the thing with chargers. For a Level 2 charger to provide 9.6 KW at 240V, it needs to pull in 40A. If your charger is set for 30A max and say for some reason the input voltage is 200-220V at your charger, then the peak power is limited to between 6KW - 6.6KW. This could be why you are only getting 5.9 KW at the car.

I have a 440V 3 phase connection for the wall box and am able to pull in 11 KW, but only 1.7KW from the Level 1 home charger because it is limited to just 8A peak current.
