Porsche 997 Turbo no boost (Only 0,6bar - 87psi)
My turbo only has 0,6bar (should be about 87psi?)
I have checked for leaks, but couldnt find one.
The vtg units works and i can move them by hand.
What can i do to check what the problem could be?

Sounds like you have a leak somewhere, would pressure test again and check, don't exceed 28PSI during your leak test. But you want to test atleast upto 25PSI.

Post #8 in the thread above shows how I pressure test.

.6 bar is limp mode. do you have any stored codes? try resetting ecu with battery negative off for 15 min.

I read out the dme with piwis2 - there is an error p0018 writen down.
When i run the car and log the cam - i see that it is permanent -14,5° and it wont change when i put the pedal down - The other side works.
But i think that error wont be related to no boost?
I only have piwis2, but i think with that i cannot log?
I made a pressure test and it holds 1,5bar for about 5minutes, after that it is around 1-1,1bar.
How can i test the blow off valves?

I'm not the most knowledgeable about this but if your cam reading is stuck in one bank and the other bank's cam is operating within parameters could it not be a spun camshaft and thereby causing the limp mode? I have heard of a few instances where it has partially spun but the car seems to operate like normal except for boost being cut. Have you looked up the code (P0018)?
It sounds like you don't have a boost leak.
