I will look in the morning to see if anything is lasted, it may have to be plugged into STAR

What temp does the guage read when the car is fully warmed up, If the header tank is showing correct levels when the car is standing then the problem is more likely to a sticking thermostat or duovalves...

No duo valves in this one, well I cant see them, no pump either

I must stop posting so late at night,,I thought that I read ML but it is an E class211
So 300 in the link is the pump and that needs to be checked to see if it is working

I suspect it will be the valves that sit under the master cylinder at fault.

Possible but they always fail in the hot mode, ie no voltage going to them
