EPC lights are relatively common in Volkswagen vehicles. After opening the key door, the vehicle starts a self-check and the EPC light comes on for a few seconds then goes off. If the vehicle still does not turn off after starting, it means that there is a malfunction in the vehicle's mechanical and electronic systems. Generally speaking, there are two possibilities for the EPC light to come on. First of all, the throttle valve is dirty and needs to be cleaned. Another situation is that the brake light does not come on and the brake switch and wiring need to be checked.
