Hi friends, I have not written here for a long time, the reason is that I bought other national classic cars ( Seat ) and dedicate a lot of time to them.
I thought I knew the car well after so many years but it is that this time I do not know where
The S2 has been driven by my son and for some time now we have problems with the car.
It is long to tell but I will make a brief summary.

The car stopped working well the turbo since entering a metal washer in the intake tube (2013) was at most 1.1 bar.
About a year and a half (2014) I got a turbo in good condition from a friend and I installed it, there was no way it worked well, I checked everything ............. in the end I disassembled Admission of the turbo and I saw that the compressor wheel had been destroyed all (we do not know the reason because in the previous turbo if we saw the washer but in this we do not know why) ............... ....... only reached the pressure at 1.1 bar again and also went up very slowly.
Wait two years until you can take the time and change it again.
The issue is that by November 2016 we changed it again and finally everything worked fine, it went up to 1.5 bar, it was perfect, but at 2 weeks it started like the previous ones, to increase the pressure little by little and it did not exceed 1.2 Bar ... we have reprinted everything
VagCom no errors, everything is fine .................. has me completely lost.
I no longer know where to look, I need some advice where to look and what may be the problem so the turbo pressure is cut.
Changed Turbo,
Changed wastegate.
Membrane wg check
Spring wg change
Check N75 K (for H)
Test circuit tightness.
Idle valve

, the diverter is revised (forge) and has no leakage, I have changed the potentiometer and also the Maf, it seems to have improved somewhat but it is not comparable to when it worked well.
