The weird thing next was that I turned off the ignition and then started the car right up with the engine then running beautifully and the light disappeared. I drove all the way home with no problems. I'd like to understand what the hell happened and if this is likely to happen again.

So EPC stands for electronic power control right? Does this originate from the ecu or is this a sensor related problem? Any help would be greatly appreciated. TIA.
Did you find out the cause / fix?
This exact same scenario happened to my daughter's 2000 A4 2.8L Tiptronic
