Electronic Power Control Warning Lamp
WARNING: This page is about a different car, the 2008 Volkswagen R32. However, it is still accessible from the selected car via links, so may be relevant.
"EPC" is an acronym that stands for the Electronic Power Control (E-gas).
The ECM monitors all EPC components after the ignition is switched on.
If a malfunction is recognized in the EPC system during the operation of the engine, the ECM switches on the EPC which is located in the instrument cluster and an entry is stored in the DTC memory of the ECM.
