Does anyone know how the pressure conver (53) works ? What does pressure sensor see at what condition etc.

That is a vacuum operated "transducer" or solenoid. It is simply a electricly
operated switch-over valve to actuate the egr valve. When egr isn't needed
anymore, vacuum is vented back out the vent line through the small filter.
I wouldn't recommend tinkering with EGR on the turbo motor due to fuel and
air mapping accounting for it in the IFI engine control unit.
If you trick it into a lean condition, say good bye to the pistons.
The turbo 606's don't suffer from sludging badly when they have good
synthetic oil and clean fuel. Like Rick said, It may only need cleaning
every 100k or when glow plugs head south.
