Why Is My Audi Check Engine Light On?

why is my audi check engine light  on?
Audi El Paso welcomes you to discover why your Audi check engine light is on.

The check engine warning light warns drivers of possible engine issues or complete failure. Your vehicle's check engine light may turn on because of many reasons. It might be anything from sensor failure, an alert to perform preventive maintenance (such as an oil change), or even warning drivers of major problems that might cause engine failure. So, even if the check engine warning light comes on, it might not be a total disaster. However, if and when your check engine light comes on, you should bring it to us for a full diagnostic inspection. Even if nothing acts broken, having it diagnosed accurately can mean the difference between needing to replace the engine and a cheap repair.

Old Gas Cap

Loose Gas Cap

Something as simple as forgetting to replace your gas cap or not replacing it completely could easily cause a check engine light. Your gas cap might need to be replaced during your ownership. After 50k miles, you should consider replacing the gas cap. If you feel you should replace your gas cap, we highly suggest genuine OEM replacement parts. Using parts from DIY stores will work in an emergency, but nothing beats parts from the manufacturer.

Oxygen Sensors in Your Car are Failing

Old O2 Sensors

Several sensors give information to the engine to help it run more efficiently. However, missing readings from components like the mass airflow sensor or the oxygen sensors can trigger a check engine warning light to come on. If your vehicle is running normally, a faulty oxygen sensor is the likely reason. This may mean that the vehicle is fine, but because the engine is not getting the info, it triggers a warning. Even if your vehicle feels unaffected, you should get your car checked out immediately to rule out any potential larger problems.

Failing Spark Plugs

Faulty Spark Plugs

Spark plugs are essential to the performance of your vehicle's engine. As the name suggests, they give off a small spark of electricity, which then ignites the gas and causes your engine to run. Spark plugs require accurate measurements for peak performance, and if the spark plug setup is too small, it could cause a check engine light. Some symptoms of old spark plugs include diminished fuel efficiency, slower acceleration, and an engine that just doesn't run smoothly.
