Any solutions yet? I’ve got the same!
Left it overnight and driven twice this morning with no issue!I went to the MB Dealership and they declared/classed it as a "Breakdown" . A RAC Mercedes Benz Technician came and plugged in a diagnostic machine.
Showed historical faults but not live current faults. So nothing could be done. His words were "typically with new vehicles turning it off and off again usually resets the issue and it disappears which isn't helpful.
As it stands, there has been no further warning lights and it's considered just " teething problems with new motors".
