Good luck man!
Do you have ISTA?

I just replaced the tank purge valve as a preventative and confirmation, since it wasn't terribly expensive and it was throwing that code. Still same bad idle and stall issue so just order the IVM. Just ordered a brand new genuine OEM IVM (Integrated Supply Module) for $320 so will see if that fixes the issue.
I'll fully open the old one to settle the question once and for all. I expect I'll find more hidden fuses and relays, when I do. After doing more searching, this damn box is apparently a known failure and plagues multiple models of BMWs.
