I was driving last night from work and out of a sudden i lost power trying to accelerate, didnt worked, i stopped, and i can hear a hissing sound very loud from under the bonnet, i check the engine and it looks like a pipe is blowing air with a lot of pressure, and i found a tube that it looks like snapped, attached a picture with the pipe that blows air, anyone know what it is ? I cant use my car right now im very sad its Christmas and i dont have a car

Not exactly sure but I suspect pressure sensor hose (post CAT?).

Looks similar to mine sort of (530D LCI) but you seem to have a different CAT or DPF arrangement.

What car is this?

Is there a loose hose flopping around that reaches that pipe? You have the eyes on the problem. And a full model number would help, eg: 520d. If you don't know it, look on the label on the door jamb.

Its 520d yes busines edtion msport, in was a hose about 10 inch there, and its disconected from both sides as i said air with a lot of pressure comes out from that tube that i circle with red, atm is at kwik fit but they are slow af, so tomorrow morning im gonna go somewhere else at a proper mechanic, cos it seems they dont have a fkin hose, and they put me to wait till next year,

Looks like hose 4 here: RealOEM.com - Online BMW Parts Catalog
Looks to connect to pressure sensor 3.
If it were mine, I'd get a length of hose to go between the points and see what happens.
