The check engine light on your Audi is there to alert you of imminent problems with your vehicle. There are several problems that can be wrong with your Audi, so it is never a good idea to ignore the problem.
This warning light is often an indication of a serious problem, and without the proper mechanical care, you could end up on the side of the road. Let’s look closer at some of the most common causes that will make the check engine light come on in your Audi.
What does the check engine light mean?
If you notice the check engine light turns on in your Audi and does not turn off, this is a sign of a problem in your car. It is often difficult to know what causes the check engine light. Your vehicle may still feel as if it is running properly when the check engine light is illuminated. Other times, your engine may stop running entirely and you will find yourself stuck on the side of the road.
Even when the vehicle continues to work after the check engine light comes on, it is important to visit a mechanic right away. There may be a serious problem inside the engine and the issue will just get worse over time.
Potential Problems Causing the Check Engine Light Illumination
The check engine light can turn on for many different reasons. Sometimes it is as simple as the gas cap not being on tight enough. If you are driving around and the engine light comes on, you can check to see if the gas cap needs tightened. This may fix the problem. Sometimes it is as simple as getting a professional to replace the filter inside the car to see if this will help.
However, many times when the check engine light turns on, this is a sign of a major problem with your Audi. If the light does not reset itself after a few days, even if it drives fine, you need to take it in to the professionals. They can run a diagnosis and read the codes to see exactly what is wrong with your vehicle.
Common Causes of a Check Engine Light
The engine check light will show up on your Audi for many reasons. Some of the most common problems that can trigger that light include:
