Audi Illuminated Check Engine Light

The Leading Repair Shop in Allentown to Fix a Check Engine Light Issue in an Audi

by schearerswpadmin December 22, 2021

Technology has changed the automobile industry for the better. Now, cars are intuitive in their entirety and can alert their owners of faulty parts digitally. Audi engineers harnessed this intuitive technology and included various lights on the digital dashboard that illuminates when there’s a lingering fault. One of such lights is the check engine light.

The check engine light is a warning symbol found on the digital dashboard of your Audi to alert you of damages done to the engine or several parts of your car connected to the engine. Even if the fault is slight and not very serious, the check engine will still come on.

In your Audi, the check engine light uses a code that indicates the particular component of your vehicle that is responsible for the illumination. You can use a diagnostic scanner if you own one to diagnose the source of the issue before calling an automotive specialist to check it out.

When you notice that the check engine light of your car is illuminated, be aware and look out for other signs as you drive to your trusted Audi specialist.

Common Reasons for the Illumination of the Check Engine Light in Your Audi

There are a myriad of reasons why your check engine light is illuminated. While some causes are more severe than others, you must know the most common reasons. Below are the five most common reasons why the check engine light will come on:

Worn out spark plugs

If the spark plug in the engine of your Audi develops any fault, the engine will start misfiring. Worn-out spark plugs can also lead to a series of other serious problems that may switch on the check engine light.

Faulty catalytic converter

The catalytic converter is a device found in the exhaust system to convert harmful gases to non-harmful gases. If the catalytic converter is healthy, the exhaust system is also healthy. However, if it develops any fault, your check engine light will come on to alert you of the problem.

Oxygen sensor failure

The oxygen sensor is a critical component of your Audi located beneath the hood. It functions as a regulator of the air to fuel ratio in the internal combustion chamber. If the oxygen sensor develops any fault, it will no longer maintain a perfect ratio between the air and fuel.

A faulty oxygen sensor will cause the engine of your Audi to run rich and misfire, which will cause the check engine light to become illuminated. You might also notice that your car is idling roughly, another indicator of oxygen sensor failure that can cause the check engine light to come on.

Failure of MAF sensor

MAF is an acronym for Mass Air Flow. It has a sensor that helps the engine of your Audi to adjust fuel-to-air ratios to ensure optimum engine performance. When the MAF sensor develops any fault, the check engine will become illuminated to alert you.

Loosened gas caps

There is a sensor found around the gas cap of your Audi that senses when the cap is loosened. It is usually the first thing most drivers check when the check engine light comes on. If you forget to tighten the gas cap, the check engine light will come on. When you tighten it properly, the light will go off. If it doesn’t, then something else is responsible. Call our mechanics to inspect and diagnose the real cause.
