What is the reason for the failure of Volkswagen epc?

There are generally two reasons for EPC failure. One is that the throttle is dirty, which leads to the EPC fault light of the car. In this case, the throttle can be cleaned. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring.

EPC is the full name of engine electronic power control system, and many people also call it electronic throttle. EPC indicator lights are more common in the public. The light of automobile EPC is a fault of engine management system or electronic control, which is often accompanied by the phenomenon of engine jitter when the vehicle is idling unsteadily or cold starting.

Under normal circumstances, if the owner encounters the EPC light, he can take the following steps: restart the vehicle after turning off the engine to see if the EPC light is still on. If it doesn't light up, it means there is no problem, and sometimes EPC light will light up because of other external interference; If the EPC light is always on for a period of time, the owner should pay attention. At this time, you can check whether the brake light is still on. If the brake light can be on, it means that you must go to the 4S shop to test it with special instruments. If the brake light doesn't work, try to check the brake switch, light bulb and wiring first (sometimes it may be that the brake light doesn't work because the brake light bulb is broken, so just change the light bulb). If the brake light can come on after inspection and the EPC light continues to come on, you should go to the 4S shop for inspection.
