Hello guys im a bit stuck with my project, swapped my Cayenne Turbo S from automatic to manual gearbox out of Cayenne S, car never came from factory with manual gearbox.

TCU is unplugged with TCU plugged in car makes no boost at all.
With it unplugged it makes full boost but pulls full timing out.

What I did so far is code kessy and gateway  to manual gearbox.
I get the press clutch message in my dash now, tried wiring up the clutch switch and also with 12v on pin 39 on engine ecu.
But car does not start with key, because of the clutch message.

Engine ecu only has Code U0103
Abs has P1314 and P1315

Ecu is a Me7.1.1 and all Cayenne models use the same ECU Part Number. I have full read of Turbo S file and Cayenne S manual file.

Maybe someone has a solution or a idea there to get started.
