I have seen this one come on,then almost immediately disappear while in EV mode with a full charge: etron gasoline engine light [white color]. Found it listed with the other dash alerts in the user Audi guide. There is NOTHING online about it. I've had other alerts that stayed on all the way to the dealer,yet showed no codes: EPC, and the MIL,system indicator light which indicates a malfunction in the engine electronics.
There was one firmware update that caused the emission control light to come on for no reason.Poster on SpeakEV, Febuary 5,2016:

04.09.17 update: the MIL lights were issues,once the dealer actually had an error code.I've had my charge port sensor replaced,and the module.
