What does EPC mean?
EPC stands for Electronic Power Control. It monitors systems involved in throttle response, engine power delivery and related sensors.
If a fault is detected, the EPC light may illuminate and the car can enter reduced power mode.

EPC Warning Light Meaning UK
The EPC warning light usually appears on Volkswagen Group vehicles such as Volkswagen, Audi, SEAT and Skoda. It often relates to throttle control, engine management or electrical system faults.
Can you keep driving?
If the car drives normally, short journeys may be possible. If power is reduced, misfiring occurs or other warning lights appear, get it checked urgently.
Some EPC faults can worsen quickly.
