Why Is My Volkswagen Check Engine Light Illuminated?

why is my volkswagen check engine light illuminated?


Group 1 Volkswagen Hub City invites you to find out why your Volkswagen check engine light is illuminated.

The check engine warning light warns drivers of potential engine issues or even complete failure. Your vehicle’s check engine warning light may turn on due to several reasons. It might be anything from sensor failure, an alert to schedule preventive maintenance (such as an oil change), or even warning drivers of potentially significant issues that may contribute to engine failure. So, just because the check engine warning light comes on, it may not be a complete disaster. However, if and when your check engine warning light does come on, we suggest bringing it to us for a full diagnostic inspection. Even if nothing feels broken, having it diagnosed accurately can be the difference between needing to replace the engine and a simple fix.


Your Gas Cap is Failing

Old Gas Cap

Something as basic as forgetting to replace your gas cap or not replacing it completely could easily trigger a check engine warning light. Your gas cap will probably need to be replaced during your time of ownership. After 50,000 miles, you should consider replacing your gas cap. We highly recommend genuine OEM replacement parts if you feel you should replace your gas cap. Parts from big box stores can work in an emergency, but nothing is better than OEM parts.

O2 Sensors in Your Car are Failing

Faulty Car Oxygen Sensors

Several sensors feed info to the engine to help it run efficiently. However, incorrect sensor readings from components like the mass airflow sensor or the oxygen sensors can trigger a check engine light to come on. If your vehicle seems normal, a broken oxygen sensor is the likely culprit. This could mean your vehicle is probably fine, but because the engine is not getting the data, it triggers the warning light. Even if the vehicle feels normal, you should get it checked out immediately to rule out any potential larger issues.

Spark Plugs in The Car are Faulty

Spark Plugs in The Car are Old

Spark plugs are vital to the performance of your car’s engine. As the name implies, spark plugs provide a tiny spark of electricity, which then ignites the fuel and causes the engine to run. Spark plugs have accurate measurements for peak performance, and if the spark plug gap is too small, it could possibly trigger a check engine warning light. Symptoms of bad spark plugs include diminished fuel efficiency, slower acceleration, and your engine just does not run smoothly.
