EPC lamp is a common problem of Volkswagen series cars.

Usually, if the EPC light is on, you can restart the vehicle after the flameout to see if the EPC light is still on. If it doesn't light up, it means there is no problem, because sometimes EPC light will light up because of other external interference.

If the EPC light is on frequently for a period of time, you can first check whether the brake light is still on-if the brake light is on, it means that you must go to the 4S shop to test it with special instruments; If the brake light doesn't work, you can try to check the brake switch, light bulb and wiring first.
