Many thanks mate :) and my last question..I have measured this with VAG COM. In the end of the graph you can see this 3 peaks. First for third gear with full throttle, second for fourth gear and third for fifth gear. You can see that specified turbo pressure is higher than actual..it is due to SVBL or it is problem of turbo?

I mean, from graph we can see real turbo pressure is about 2000 - 2100mBar. But limiter is set to 2350mBar. Why it is not real pressure about 2300-2400mBar, when specified is up to 2500mBar?

if you have log text file, post it, I will see the problem , but if you have a peaks maybe problem is in some limiter, or mechanic in vacuum actuator, n75 or turbine.

when you make a log file, must be in gear 3, from 1500rpm to 4000rpm with full throttle
make measurement of rpm, desired and actual boost presure and n75 valve.

ok, you have overboosting between 2200 and 3200 rpm. Check vacuum , n75, or turbine has soot in it.
