Ok. I ll tell in english ;)
1. If u don t use egr, it means that u never recyrculate gas in the engine, so the dpnr suffer more, because all dirty gasses always goes into dpnr, instead part of them recyrculate inside egr and be cleaned by it;
So if one close the egr, he need also to eliminate fap.
If u didn t do it it, but your car still works, means simply that with the typical use that u make with your car, it s always able to have regenerations, alias, u mainly use it not into city traffic. Good for u ;)
With closed egr and a normally working dpnr, the risk of failed regenerations, and have a full dirty filter, is behind the corner.
2. Lexus dealers in Portugal must study little more; i don t discuss that your car is still able to move, i simply say that this solution is wrong. With your connection, everytime the egr open, part of the pressure of turbo is lost and return into aspiration.
So u loose power.
The right solution is the one me and Fonserg suggested 3 years ago.
My car worked for many more then 30000 km without egr, without dpnr (i used a empty tube instead of dpnr and an electronic emulator), and for s period i also spritted water/alcool injection inside it ;)
