Volkswagen epc explains what is wrong.

Volkswagen's instrument shows epc, indicating that there is something wrong with the engine's power control management system. The reasons for epc failure are:

1. The throttle valve is too dirty and should be cleaned.

2. The brake light is not on. Check the brake switch and wiring.

3. The battery is low.

4, gasoline quality problems.

Epc fault solution is:

1. Clean the throttle body.

2. Clean up the engine carbon deposit.

3. Rewrite the relevant data of ecu. Volkswagen models include: Volkswagen Phaeton, Volkswagen Magotan, Volkswagen LaVida, Volkswagen Sagitar, Volkswagen Bora and so on. Take 20 13 Volkswagen Phaeton as an example. This is a big car. Its body dimensions are: length 5 179mm, width 1903mm, height 1450mm, wheelbase 300 1mm and body weight 2260kg.

Precautions:

If EPC light is on frequently for a period of time, first check whether the brake light is on, first check the brake switch, light bulb and wiring (sometimes it may be caused by the broken light bulb of the brake light, just change the light bulb). If the EPC light continues to come on after checking the rear brake light, you should go to the 4S shop to check it.

The common EPC indicator light shows two colors, one is yellow and the other is red. The epc fault light is yellow, and the car can run normally, so it needs to drive slowly to the maintenance point for vehicle maintenance.

The epc fault light is red, indicating that the situation is serious. You should pull over immediately and contact the relevant maintenance personnel for maintenance. If you drive forcibly, it will directly affect the core components of the car or the safety of driving.
