I changes 3 turbos + charge pipe but still have same problem with code 2c57(Charge-air pressure control, lower value: Boost pressure too low). check the notepad file to get the link to my log

Hello.
You don't want to listen to what they tell you.
Then learn the materiel yourself.
******************************************************* **********
You have already changed three turbines. This is from your words!!!
I think it's cheaper for you than to learn materiel. If you don't want to listen, then don't ask... Wasting time on you is pointless!!! Go to the supermarket and buy 10 turbines and change them every day.
It just won't change anything. If you don't want to listen to what they are talking about, no one will help you!!!
don't ask anything!
On your part, you didn’t even say thank you, for the fact that people are wasting their personal time trying to explain to you how it all works.
YOU do not hear it, do not see it, and are trying to explain to us that everything works for you. I don't understand! Why make a theme?

As my grandmother used to say -
Granddaughter! - what you want to eat, - I have already pissed!!!
_______________________________________________________________
Sorry, But maybe now you will read all the posts again and learn to Read and listen.!!!
Learn the materiel yourself!!!
A little advice for you. Open ISTA+ and read about D.V.S. and how it works! Then you don't have to ask!

If my post helped you hit the thanks and reputation button. Thank you

I really do appreciate all the help .I am sorry if i got you mad but i really don't know much about engine and their component. I may know them physically but not the names or how it work. i try to solve my problem myself because most mechanic here are not use to bmw cars.
Once more i am really sorry

Here is what i get after 20 seconds of car been on
The vacuum dropped immediately after the car is switch off
No there's no way to take the T fitting vacuum pipe inside the car

NO WAY? do you have no vacuum lines, masking tape, t-fittings? Cant roll down your windows, the doors dont open, they are welded shut?

just drive the car to the wrecker then.
Bro i am in Africa where there's much limitations.
It took me 1month to get a vacuum pump from Dubai.
I will have to see if i can get a vacuum line that long
