What's wrong with Volkswagen epc lamp?

When epc appears in a car, it means that the mechanical and electronic system of the car has failed. Common automotive epc failures are mainly caused by the following situations:

1, the brake light is not on.

Check whether the light bulb is damaged or burnt out, whether the wires and plugs are connected properly, and carry out maintenance according to the corresponding situation. Generally, it can be solved by replacing the brake light bulb.

2. Throttle carbon deposit is too thick.

Oil vapor adheres to the throttle valve and combines with a small amount of dust in the air to form sludge. After a long time, it becomes carbon deposit. In this case, cleaning the throttle can generally solve the problem of EPC lamp.

3. There is a leak in the air intake system.

If there is a leak in the air intake and crankcase ventilation system, the EPC light will light up. Before judging this fault, be careful not to pull out the dipstick and open the fuel cap when the engine is running, so as not to cause false alarm.

The car epc indicator light is on, and more than 90% of the cases are because the electronic throttle is dirty. In reality, if the EPC indicator light is on, you should go to a 4S shop or a professional auto repair shop in time and let the technicians read the fault code with the computer. Only by determining where the problem is can you fix it.

Special reasons for EPC indicator light:

1. If there is a problem with the oil, the EPC fault light will also light up.

2. If the engine is turned off due to improper operation, this indicator light will also light up and go out after re-ignition, indicating that everything is normal.

3. Abnormal cylinder pressure and poor working conditions.

4, driving computer failure.
