When Volkswagen LaVida 1.6 refuels, the throttle light will light up.

1, because the throttle is dirty, the mixture is too rich.

2. The engine has too much carbon deposit, which leads to unqualified exhaust emission. Is there any reason for too much carbon deposition, such as regular maintenance or poor oil quality?

3. When the engine oxygen sensor fails, it will also cause the throttle fault light to light up.

When the throttle fault light is on, the owner should not be too anxious. You can stop the car first and then wait for 5 minutes. You don't have to step on the clutch, you can start it by pressing a button directly, so that the vehicle is in a state of power. In this way, the vehicle will self-check, and then observe whether the fault light on the instrument has gone out. If it has been extinguished, it can be started normally.

If the fault light is still on, don't worry, you can start the vehicle normally and confirm the state of the vehicle. If there is no obvious jitter or noise change compared with usual, you can drive to a nearby repair shop for inspection and maintenance. Of course, if there is obvious jitter or loud noise, it is recommended not to continue driving and ask for help nearby.
