Error 2D25

Hello from Russia.
I had a problem after up-dating of a firmware of control box by the engine at the official dealer of BMW.
Now after 10-15 minutes of the active driving I have an error 2D25, the car starts to go badly, boost pressure falls to 7-9psi whereas shall be 15-16psi. After I suppress a car and I deliver again the car again well 10-15 minutes go, then everything repeats.
I have a Vishnu v3 chip (put it about 3 years ago).
How to me to win this error?
Thanks for the help)
Also excuse for my bad English)

Thats a tuner code buddy. If Im not mistaken thats a Mass air manipulation,mass air cover. With the JB4 I adjust my fuel open loop mapping and problem went away. It could be different for every car though but try that out and see if you can increase it in incriments of 5 until it doesnt throw that code. But its for sure a TUNER CODE.
