@lewis @mark...

depends on the reading of the diagram.

the RED tubes are going from the Driver side Turbo up . There is no T but there are 2 lines going in different directions. One is ending on the Top of n75 valve. 

Dont know if there is a reading too.

Major work on the drivers side Turbo.  I can see that there was already some "specialist" working here. 

Take away air filter housing to get access. Take away tube with the MAF.

Changed the o ring between the metal hose and the charger

Changed the pressure hose to the wastegate. New blue silicon line. 

Changed the tube which is going away from the turbo housing in direction to the belt. No. 15 on the diagram 

there was already a damage and previous owner fixed it in a very special way

It doesnt fit to this topic but i dont want to open new discussion.

 

i have serious problems with my sway bar bushings. They are making noises like crazy. Feel even shy to drive. Squeaking like crazy. I treat some with a wrong spray and since than they are noisy. I have new bushings. Just wondering if i can change them without removing all the sway bar. 

Any advice is very welcome.

It's only a return air pipe, as the maf has already measured the air going in the system so it must stay in the system by way of returning back to pipe 14 and back into the driver side turbo inlet.

1000 km trip to Mediterranean Sea. No problems except 170 liters of gas and 0.5 liter good oil.

 

I can't push the pedal down like crazy .  I am really afraid when i see how fast the boost needle is hitting the scale until the end. Tomorrow I will check codes. Would not be a surprise if ...,

I just connected my icarsoft code reader and there is NO OVERBOOST code! So fortunately the repair of both pressure lines must have cleared the boost leak in some way. The whistle sound still there but for now i am almost satisfied.

Congratulations on finally fixing that problem. A lot of work but you've fixed a lot of weak points which will contribute to long term reliability.  I can't remember, do you have stock air filters?  A more open filter can let some of the intake and/or Turbo whistling noise through.

Hi Mark. Thank you for congrats. Maybe i could do it more quickly if i had more time to work on the car.  

Yes you are right. Going a little bit more deep inside i found many many weak parts . Some are repaired by the previous owner but in a very unprofessional way. Lesson: never buy a car with italien registration. You dont know for shure if the service books are not cooked in some way. 

 

I an using stock air filters. The noise occurs first time when i worked under the car to change some tubes.
