Nope, definitely not. The code is no longer there and cleared itself. It was odd this time because the code wouldn't clear with VCDS or a generic OBD2 reader, but now is no longer there and fixed itself.

At this point who knows but it seems electrical to mee. Like a solenoid somewhere buried in the EVAP system that is failing or occasionally getting stuck (car already has a new 'N80' purge valve). Almost everything EVAP related is brand new and OEM.
