2012 Panamera base v6

Need help! I have access to a Launch x431+
Codes are attached (ignore inactive codes)

I have another 2011 base v6 Panamera I can use to swap parts to figure out the issue.

Parking Brake Fault, Suspension/Chasis Fault, Transmission Fault, Reduced Engine Power

*CAR DOES NOT SHIFT INTO GEAR / REVERSE, BUT I CAN SHIFT IT INTO NEUTRAL.

all gauges work(oil pressure, oil temp, fuel, coolant temp, rpms)

*starts up & idles perfect


Lights on the dash: ABS, Traction Control, Brake, check engine, parking brake, tire pressure, airbag)
*Theres No light at the parking brake button, does nothing when you push/ pull it

*checked all fuses
*oil level is good
*new coil packs / spark plugs
*new battery
*AC works
* starts up & idles perfect
*radio works
* rear spolier does not go up or down
*all lights / windows / blinkers / brake lights work

I tried swapping the gateway / battery / main relay / ecm(engine compartment, passenger side firewall)

Right now I Have everything swapped back to the originals, at first I did have a bad oil pressure sensor that I replaced, was getting no oil pressure reading(fixed now with a new sensor)

I'm assuming I have a short / bad wire somewhere but not sure where to start testing Wires, i checked the injector/coil wires when I removed the intake.

 

Very hard t(if not near impossible) to read the errors from images you provided. Do you have any "Transmission fault". Do you see yellow gear on cluster and warning "Transmission fault"?

 

Yes, Transmission Fault. Most modules has a "No communication with the PSM" code and in the PSM whats sticking out the most is a Combination Sensor code. Which there's very little information online about that or what/where it is. Also it says the Combination sensor is not calibrated, every time I try to calibrate it It fails the test instantly. "Steering wheel straight, on level ground, etc"
