Yes mate, exact same problems, needed new turbo, new cat and new EGR cooler.
I vowed never to buy another DAF after spending £20k (Inc callouts and recovery) to get it finally running well.

The fact you done diff sensor would suggest same problem (it sounds like ratio is wrong) it's not, it's the turbo not working properly causing the engine to work harder.

Check all electrical connections and place for wire rubbing on loom. The canbus system is a network with each item having a specific address on system. A single wire earthing can cause any number of faults in sensors and transducers that are otherwise working correctly. Alternative a bad earth or corroded earth wire can also cause the same problems

if they are trough you need to solder them carefully as cutting them and joining them can cause more problems because of voltage change it can be repaired tho by the right person

There was an ECU update on Dafs in 2014/15s, main dealer only, free of charge also, check to see if this has been done.
I wouldn’t imagine anything to do with the turbo actuator though.

Try to calibrate the VTG, if that doesn't work you are looking between 2000-3500 for a new one.
