W212 OM642 with high diesel pressure code 11C300

I've searched the forums and no one has this specific code for the Bluetec.
CEL shows "high fuel pressure implausible" which means it is off the charts.

Looking for help to track down the culprit. I can throw a fuel pressure sensor at it, or a pressure relief valve, or a new fuel filter, or ???

Anyone have this issue that can point me at first things first?

suggest you reread the definition of "implausible" and look to the fuel rail pressure sensor and regulator as a possible fault!!
