It is the DME relay! 
Interment issues on any vehicle suck. At least with the 3.2 Carrera there is a neat technical site and every single issue on a G body 911 has been asked and answered dozens of times. I doubt there are many user forums for a new fangled pick-em-up.
I know a friend of mine ended up trading in his Lexus for a random issue no dealer could fix.
