Well, either throw Porsche diagnostics computer time at the symptom or throw expensive parts at the symptom.

These are very modern cars with sophisticated control systems, including the e-Gas which because it is a safety critical system is a rather complex piece of hardware and software engineering.

One just doesn't tap it with a hammer and fix it.

The error codes you can read out, along with the ones the tech can almost certainly read out should point the tech at the source of the problem.
