It seems like the most common light any driver ends up seeing, aside from the simple ones that let you know cruise control is activated or your lights are turned on, is the check engine light. Even if you aren’t an expert on cars, you likely know how important the engine is, and it can be a bit disconcerting when that little symbol pop up in your gauge cluster. To provide some reassurance, we’re looking at the Volkswagen check engine eight and other warning lights, and what they mean for you.

There are a variety of reasons for a check engine light to come on, which is why it tends to pop up more frequently than other lights, which tend to be very specific. The first thing to note is the color of the check engine light is yellow, a color used to indicate a warning rather than an emergency.

Gas Cap: We kid you not, a loose or damaged gas cap can trigger one of the scariest lights in your gauge cluster. Tighten that thing up.

Faulty Oxygen Sensor: Your check engine light is triggered by some sort of emissions issue, and this is a common culprit. Whether it’s faulty, or just really dirty, it can send out an incorrect reading and trigger your sensor.

Catalytic Converter: Your catalytic converter is responsible for converting carbon monoxide into carbon dioxide, and a faulty one not only causes pollution, but reduces performance and fuel economy.

Worn Spark Plugs: In gasoline engines, these little babies are responsible for firing up your vehicle. While they don’t need to be changed often, it’s important that you do to avoid misfiring.

Engine Overheating: There’s warnings, and then there’s an emergency. An overheating engine is one that can start on fire, and this is one instance when you should definitely pull over. Check the thermostat to see if it’s reading hot, or pull over and pop the hood if you’re unsure.
