Neff fridge/freezer feels hot down centre between the fridge and freezer compartments, making the door see feel hot too

SOURCE: Fridge is getting hot in between the doors

This is called a mullion heater and is perfectly normal as this heater prevents the area between the doors from freezing. No danger at all.

SOURCE: Does not stop cooling down

Door edges being warm is caused by what is called mullion heaters that operate to prevent humidity from condensing at these points.
Some refrigerators have an energy saver switch. Turn this switch if you have one to the energy saving position when the humidity is low. Is anything freezing in the refrigerator? If so setting the controls to a little higher setting may solve your problem.

SOURCE: Fridge freezer over heating and is not cooling fridge section

It is normal for the middle strip to be hot. Did you check the temp setting in the fridge section?
Also - you might check for blockage in the bottom. Excessive dirt/dog hair can block the air flow.
Good luck

SOURCE: Pooling of water in fridge compartment of my Neff fridge/freezer

The defrost drain is clogged. Defrost drains usually get there clog right behind the back freezer panel. Remove this to get to the defrost drain and remove all built up ice and clear the drain and you should be fine. Hope this helps.
