Hi
Can anybody check and confirm this file is original, not touched?
Sometimes (every few minutes of driving) I lost some turbo pressure while driving, istad tell me when the car has low power, real turbo pressure is aprox. 1bar lower as ecu wants, then I put foot from accelerator pedal and press again then the turbo pressure is ok again.

I replaced with new ones;
-turbo pressure control valve
-turbo pressure sensor
-airflow mass meter
- all vacum pipes are new
I also tried;
 -to block egr valve with metal plate( the same problem except mil on for egr flow)
-to block swirl flaps vacum pipe (in case vacum loose in swirl flap actuator, the same problem)
- to run turbo pressure actuator test with istad and service functions( turbo pressure actuator moves up and down from max. to min. in fast response

The fault code;
4530 DDE:Charge air pressure control deviation

I will press rate and thanks button for any answer about if the file is 100% not touched, I want confirmiration before any additional mechanical repairs on the car will be done (I assume broken vnt vanes inside turbo)  

Thankyou
