blockag in the matrix.......air ? Or a knackered water pump, have you checked circulation ? Rad should start to get warm at top and then head to the bottom when thermostat is opening.
Have you felt pipes going in and out of matrix ? Are they hot ? And either side of the control valve ? May have a knackered control valve you swapped.
Have you tried letting the car cool over night and the topping up levels in morning ?

Good start mate, it has to be a command issue or a valve that is stuck.
So water pipes to matrix are hot ? Ins and outs ?
Is so then will be a flat issue look for simular problems on that certain car.

Hope you get it sorted mate.
Also look to see if the interior tempreture sensor is clear as they normally have a fan to suck in air and that controls the tempreture.
