What is the fault when the Volkswagen EPC light is on and how to solve it?
2 Answers
When the car's EPC light is on, it indicates a fault in the engine management system or electronic control. The solution is to replace the bulb or check the brake switch and circuit. If you cannot solve the problem yourself, you should drive to a repair service station as soon as possible for maintenance. Introduction to the car EPC: 1. Definition: EPC stands for Electronic Power Control system of the engine, and many people also call it the electronic throttle. 2. Indicator light: The EPC indicator light is more common in Volkswagen vehicles. After turning the key, the vehicle begins self-checking, and the EPC light will illuminate for a few seconds before turning off. If the light does not go off after the vehicle starts, it indicates a fault in the vehicle's mechanical and electronic systems.
I just fixed this issue recently. The EPC light coming on is quite common in Volkswagen cars. I checked the brake light switch myself and found the brake lights were staying on, making it hard to shift gears. I just spent 80 bucks to replace the new switch and it worked. It could also be a dirty throttle body—I took it apart and sprayed some carburetor cleaner, which did the trick. When the throttle doesn’t respond, watch out for electronic throttle failure; unplugging and reconnecting the connector sometimes helps. A faulty sensor is more troublesome—last time the oxygen sensor went bad, it cost over 500 to replace. Start by checking the simple stuff first; if you can’t fix it, go to a repair shop ASAP. Never keep driving with it—it’s dangerous.
