Do not forget the circulation pump,,, when the duo valves are working correctly, you can feel the pulse on the outputs, some thing like a heart beat

Had this problem on my W124, turned out to be the electric circulation pump.

Looks like number 26 on the parts diagram.

thank you, I can see that on the diagram, but absolutely not under the bonnet :-( it must be hidden behind the fireproof wall? or not?
