Jetta water temperature is 90, epc stops for several hours, and it doesn't light up. After changing the throttle, epC is still on and can't afford to refuel. Solve it.

Hello, this situation is the engine electronic system alarm. After the fault light is on, the engine computer will protect it, and the valve cannot be refueled. Any meteorological software damage or poor contact of the engine will lead to alarm, so it is necessary to use a computer detector to read the fault code, and then use the fault content for maintenance inspection. I hope my answer can help you! Have a nice trip! If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
