hi, are you check boost pressure control valve n75 , n18,, and sometimes sensor G450 make this fault
Make a log with VCDS or Delphi for see turbo

I saw with vcds that the turbo pressure is ok the car goes into limp mode without hard acceleration.This car has a box with all connections n75,n18 all in one.Maybe this is the problem?With live data when the car is with limp mode the data of boost control shows 6%.

most of time if happens on 5th gear around 100-120 km/h
turbo is the problem

IF you have boost control 6% your problem 100% in turbo.

The turbo has been cleaned and i have not any strange sounds from it.I moved the variables with the hand no stucking at all.Also if it was stucking i had trouble with overpressure but now the trouble say boost pressure not reached....

What box ? Some tuning box ? Check wiring from ecu to Boost preasure sensor with light bulb.
