61100A Mercedes Fault Code :
Read the description of 61100A in MCM02T and the engine lights up for MCM02T - MCM Engine management (10A20) code, there are some possible causes for it.
The values for the coolant temperature measured at the components '10B51 (Engine exhaust coolant temperature sensor)' and '10B52 (Engine intake coolant temperature sensor)' are not plausible.
