Yup, exact same codes and symptoms as you, minus the transmission codes.
I've been doing lots and lots of Google searches too without much luck. Your thread is probably the most detailed I've found.
no STAR report yet, I read my codes via LAUNCH. Will get one and see if any additional info comes up.
Thanks for the additional link, will check it out!

The ESP code was communication from motor electronics implausible, plus a mechanical supercharger fault. Installing the jumped belt resulted in no more codes and boost again, but a bit less than normal. The lack of boost due to jumped belt probably caused the ESP code, and the mechanical supercharger fault also from the jumped belt. The next day the supercharger pulley sheared from crank hub, was probably slipping before it gave way thus less boost.
Absent suggestions I am looking at all OE parts - crank pulley/harmonic damper assembly, mounting bolt, and will do the front main seal while I'm there. New SC belt and fan belt while I'm at it.
