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 ...,

Member @ lewisweller would ask: do you feel any smell of gas when you open the reservoir ? If not ok. If yes, head gasket.
You wrote thermostat is new? You installed it? How the coolant was refilled? I bought a special vacuum refill tool because Cayenne V8 engines are well known for air pockets. Not just enough to put water inside until max. Reading.
When you sit in your car and watching the temp gauge climbing up, what happens with the temp if you rev the engine a little bit for one minute. Can you see the temp dropping?

That would be great Thomas - maybe you can start trying to increase boost now!
I will have a 1000 km trip to the seaside now. We will see how the car will manage this

Hi. Yes it fixed the issue. Look for bad wiring/ isolation of wiring. I am pretty shure it was my problem. Get in touch with something & fuse blown. New fuse and proper isolation. Didnt come back the code. Good luck
-
the overboost code didnt come back until now. Maybe i am really lucky with weekend repairs.
-
@lewisweller could you explain the airflow Lewis? I thought this is some kind of ventilation for the turbo charger. The hot air is running through this pipe up to the oil air seperator right?!
-
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.

I am glad to fix all this broken / weak points. But in the end, the whistle noise still there.

Thank you for this info. Hope not to difficult to take out the filter housing. After you go through wheel housing?
tomorrow if there is time will check the driver side down at the wastegate.
-
To get access to the small pressure tube i disconnected all this stuff around. Airbox. Tube with the MAF. Tubes which are going to turbo charger cold side outlet. But, this small tube is hidden and i can hardly get my hands to the end where its connected to the Charger housing. No way to change this. Try from up and down and from wheel well. Nothing.

If someone need a membrane for this crankcase ventilation..
They have it on sale now. I bought some just to have it if needed.
Porsche sells just the entire unit which is expensive.

Very good picture. Thank you.
I see you take away the connection piece - part no. 3 - which has a gasket.
I don't have this gasket and can't get it until tomorrow. I will see if I can manage to change the pipe without removing the plastic part no. 3

@ Lewis . Thank you for taking care.
Yes I remember the hose is a little bit hidden and difficult to get to. I will inspect and try from up or underneath. I will take pictures. Boost pressure reference hose ! Thankx for technical lesson.

First of all thank you very much Mike for your detailed post.
There are 2 lines in direction to the passenger turbo. One to the wastegate, one to the turbo housing . I am talking about line 10 which is measuring the ambient air. This one i squeezed, hope to reduce the air flow to n75 and see some changes. Weekend i will check this entire line down where its connected. Hope to find a leak
-
Checking the lines going away from n75 valve again. I can bet the pressure lines to wastegates are very tied. The line which is going to the cold side of the charger how Mark call it, i am not shure. I squeezed the line with the zip tie. Almost closed. Wanted to see what happens if the air stream to the valve / from the valve is different. Went for a test drive just to see if something changed. It did interestingly. I hope i am not paranoid but the way how the car is acting is different during acceleration. I will change this pressure line these days and report back what happens.
-
Mike you treat your beast very hard :-) if I am doing so my boost will hit the sky.
I need to figure out how to get access to WG. Difficult and nobody here knows looks like.
I am not Shure if the noise in your video is the WG or DV Valves
-
@hahnmgh63 thank you very much Mark.
Ok i will need to crawl down and disconnect and check all pressure lines again. MUST be somewhere there the fault.
-
I am pretty sure the noise/ pressure relief is coming from the passenger side. Driving through a tunnel with open windows make me believe it's something on the right side.
Seal on lower tube is changedPressure hose to wastegate changed
Is it possible to get access to the wastegate linkage like on the picture (pics from member @danyol)
There is another pressure hose which is going from n75 to charger housing.
Measuring what? Blowing through this pipe makes air escaping at the end of the air tube which ends in the air filter housing.

Very good mike but i dont have a Gopro.
i will try to make a video with my mobile

Very similar on the 955 to the 957. Scroll down and download his pdf. I installed mine under the plastic trim panel so you don't see the can but it does catch a fair amount of oil that would otherwise be coating the Intercooler, throttle body, intake manifold, and turbos.
Thank you. I will check the post again

You are welcome anytime!

@lewisweller first time i dont agree with you Lewis. My first Indy did it exactly the same way like you discribed. Topping of is not enough IMO.
