Ok, just returned from my last investgations. Directly at the pump exit it can easily achive 8 bar pressure, when the fuel line is disconnected. However at the Schrader test valve at the right cylinder I am just getting around 2 bar.
The car is still under warranty.
I am still trying to understand the full constellation of the fuel system, somewhere the fuel pressure is limited to far down.
