What does it mean that the Touareg dashboard shows EPC?

EPC(Electronic Power Control) is referred to as engine electronic power control system, also called electronic throttle, which is composed of sensors, controllers and other components. EPC indicator light is very common among the public. Usually, after the ignition switch is turned on, the vehicle starts self-inspection, and the EPC indicator light will light up for a few seconds and then go out. If the light does not go out after the vehicle is started, it means that the mechanical and electronic system of the vehicle has failed. When EPC indicator light is on, abnormal phenomena such as poor engine idle speed, occasional flameout during driving or idle speed flashing may occur. When the above situation occurs, it is suggested to go to the garage, use the automobile computer detector to detect the engine system, read the fault code and dynamic data flow, then find the problem, and then make judgment and analysis according to the detected fault information and parameter information, and maintain it well! Analysis: Under normal circumstances, due to the air quality of the driving environment, the throttle body is too dirty, so that the throttle can not reach the predetermined opening, that is, the required load value can not be reached, thus causing this kind of fault of the car. The solution is to clean the throttle body and re-match the throttle body with the automobile computer detector. Description: EPC electronic power control system does not refer to an independent functional component, generally including throttle control unit, accelerator pedal position sensor, brake light switch, etc. Once there is a fault, it is recommended to go to the automobile specialized shop designated by the manufacturer or the automobile repair shop with good reputation and good technology for inspection and maintenance in time. Don't be blind!
