What does the EPC light mean on a Volkswagen dashboard?

[CameronFitz]

EPC stands for Electronic Power Control, which means engine power electronic regulation (electronic throttle), so many people also directly refer to it as the electronic throttle. It is commonly found in Volkswagen series models. Below is an introduction to related content: When the EPC light appears on the car dashboard, it indicates a malfunction in the vehicle's mechanical and electronic systems. The most common scenarios are: 1. Dirty throttle body. In this case, the throttle body should be cleaned. 2. Brake lights not working, requiring inspection of the brake switch and wiring. Additionally, the following reasons can also trigger the EPC light: • Poor fuel quality can cause the EPC light to illuminate. • If the engine stalls due to improper operation, this light will also come on. If it turns off after restarting, it indicates normal operation. • Intake system issues, such as leaks or blockages. • Abnormal cylinder pressure or poor engine performance. • Faults in the vehicle's computer system, occasional malfunctions, or false alarms.
