what is the procedure considering chamber flushing,..just remove the

Get the car on an incline, nose down, so that you get all the fuel and crap out when you loosen the by-pass valve banjo bolt (first) and remove the supply banjo bolt (on the pump). Refill the chamber with the primer pump and drain a couple of times.
Disconnect the banana hose at the steel return line, with engine idling, and hold into a small container. Check for a strong flow at idle that increases further with rpm. A dribble indicates that you have a blockage somewhere.
No guarantee that this will fix it but a couple more items to eliminate.
Just remember that very common causes of rough idling are the very variable quality of diesel fuel and low cetane levels due to poor mixing, or insufficient levels of, 2-ethyl hexyl nitrate - the chemical additive used by Oil Companies to raise the cetane level. Some Countries and Oil companies are much worse than others. Are you perhaps expecting too much??
It can take several tank refills to purge out a bad load of fuel.

I suggest that you get another opinion on that from another more competent and reputable Boch agency.
