You may be shocked to learn that most cars built since the 1990s were developed and equipped to independently detect faults and performance difficulties and notify the driver of such problems. That makes your Audi a very intelligent vehicle. The check engine light on your Audi’s dashboard is one of many warning signs that flashes when a connected system malfunction impairs the functioning of your vehicle.
In this article, we will go over some essential information on why does the check engine light illuminate in your Audi, including what it means and how to diagnose issues, and common problems involving an illuminated check engine light, along with what you do to maintain the health of your Audi to hopefully prevent this kind of driver alert from happening in the first place.
What the check engine light is trying to tell you
The check engine light on your Audi signals to the driver that something isn’t exactly right with its operation, no matter how severe or minor. Once the check engine light comes on, a code that identifies the particular component or location of the malfunctioning car is also released.
As we previously stated, the severity of these problems varies, ranging from a loose gas cap to a significant engine issue like a failed spark plug. Many drivers have personal diagnostic scanners which can pinpoint the problem’s location so they don’t have to wait for an automobile expert to diagnose it.
However, it’s crucial to keep in mind that if the check engine light illuminates, it’s preferable to have an Audi expert inspect your car to protect your safety.
Why Does the Check Engine Light Illuminate in Your Audi?
Even though the check engine light may indicate a wide range of problems, it’s helpful to understand some of the most frequent reasons why it illuminates. The top 5 related problems that frequently set off the check-engine lights are as follows:
Spark plug problems
The mechanical system of your Audi’s spark plugs might lead to engine issues, which then switch on the check engine light. Spark plugs might degrade or stop working with time. This issue should motivate you to schedule service with our professionals as soon as possible because it is more critical.
Loose Gas Tank Cap
If the gas tank cap isn’t securely locked, that is one of the fundamental reasons your car’s check engine light can be on. If the cap wasn’t tightened completely, do so and check to see whether the light turns off. Within a few days, the light ought to go out.
Catalytic converter issues
Catalytic converter issues are probably at blame if your car fails the emissions test. The check engine light on your car will also turn on if there is a problem with the catalytic converter. The primary function of the catalytic converter is to turn carbon monoxide into carbon dioxide, something it cannot do when it malfunctions. Regular oil changes are an excellent method to keep your catalytic converter from needing repair in the first place.
Mass Airflow Sensor (MAF)
Without a functioning MAF sensor, your engine can’t properly regulate the fuel and oxygen proportions for optimum performance.
Error in the basic fuel system
A loose or improperly fitted gas cap is the most frequent fuel system issue that sets off the check engine light. It is a reasonably straightforward problem with a straightforward fix.
Oxygen sensor malfunction or failure
The oxygen sensor controls your Audi’s engine’s fuel and air combination. Your automobile can consume fuel faster than usual once the sensor stops working correctly. The oxygen sensors need to be fixed as soon as possible to prevent further harm to engine parts like the catalytic converter and spark plugs.
Whenever the check engine light illuminates your Audi, a professional should be consulted unless the driver can quickly fix the fault, like a loose gas cap. Be warned that if the engine light on your Audi starts to flash, the engine may have more significant issues. As soon as you can, stop driving your car if the check engine light begins to flash, and contact our service department to have it fixed.
Why Should You Take Your Car to Be Fixed
It must go without saying that the engine in your car is one of, if not the most, important parts of your Audi. The causes of the check engine lights are not limited to the usual ones mentioned above. Even if your car doesn’t exhibit any noticeable symptoms, driving while the check engine lights are on might be dangerous.
Recall that the check engine light signifies that the onboard diagnostic system has detected a problem. This computer is generally reliable and only turns on the light when something requires immediate attention.
Don’t disregard the check engine light because doing so could lead to decreased performance or, even worse, emissions that could harm your car’s exhaust system. What might be a simple and affordable remedy today could become something significantly more expensive tomorrow.
