Epc dash light

The EPC (Electronic Pedal Control) is the "fly by wire" system that controls the throttle, it took the place of the cable that went from the gas pedal to the throttle body on VW. If this light is on and there is also a P0102, MAF (Mass Air Flow) related code stored in the vehicle's computer, the EPC may be caused indirectly from a faulty MAF. If the EPC is on and there is no other codes stored, it could be a faulty electronic throttle body or need to be re-programmed. The vehicle's computer must recognize the throttle body so when replacing it with new or used it will need to be programmed at the dealer

You will not turn the light off until any fault is rectified.
