Volkswagen epc and engine are on at the same time. What is the reason for the car epc light?

EPC (Electronic Power Control) is the electronic stability system of the engine, which is generally common among the public. When Volkswagen's EPC light and engine light are on at the same time, it means that the system has detected that the engine and its electronic system have failed.

When we turn on the ignition switch, the car will automatically enter the self-test procedure, at which time the EPC indicator light will light up for a few seconds and then go out. However, if the indicator light is still on after starting the vehicle, it means that the engine or its electronic system has been detected to be faulty. 90% of the reasons why EPC indicator lights up frequently are due to unclean electronic throttle and carbon deposition. At this time, we only need to go to the 4S shop to clean the throttle and clear the fault code, so we can eliminate the fault.

The reason why EPC fault indicator light is on

Air intake system leaks or is blocked.

The throttle is dirty or has too much carbon deposit, etc.

The fuel oil used is not up to standard.

Abnormal internal operation of engine

Failure of EPC sensor leads to false alarm.

The electronic control unit is out of order.
