I’ve replaced the following,
Both Vanos solenoids
Eccentric shaft sensor
Valvetronic Motor
Like a million Throttle adaptations..
I am beyond perplexed. Using ProTool I can see the engine load never exceeds 60 percent with throttle reading 99 percent on the raw gauges part of the app.
The car has a StageFp tune with headers, still get the code and throttle issue when flashed back to stock software.
Any advice or insight would be great!

I wouldn't say im an expert, but It could be that the eccentric shaft itself is stiff or jammed. Have you tried doing the eccentric shaft stops learning procedure?
Other than that i would probably remove the valve cover and check the eccentric shaft to make sure it can move freely.
