Why Does the Check Engine Light Illuminate in Your Audi

Your Audi is an exceptionally intuitive vehicle; in fact, you might be surprised to learn that most vehicles since the 1990s have been designed and engineered to detect their own malfunctions and performance issues and alert the driver of such issues. Your Audi’s check-engine light is one of many dashboard warning symbols that illuminates when there is a related system issue occurring, causing your car’s performance to suffer. In this article, we’ll go over some basic information about your check-engine light, including what the check-engine light means, how to diagnose problems, the common issues associated with an illuminated check-engine light, and what you can do to keep your Audi in proper working condition – hopefully to avoid this type of driver alert from occurring in the first place.

What your check-engine light is telling you

Your Audi’s check-engine light serves as a warning system to the driver that something isn’t quite right with its functionality – whether mild or severe. When the check-engine light illuminates it simultaneously emits a code that indicates the specific part or area of the vehicle encountering a malfunction. As we mentioned, these issues range in severity, from a loose gas cap to a serious engine malfunction like spark plug failure. Many drivers equip themselves with their own diagnostic scanners that tell them where the issue is so that they don’t need to wait for an automotive specialist to tell them what the problem is. However, it’s important to remember that any time the check-engine light comes on it’s best to have a Audi specialist check out your vehicle to ensure your safety.

Most common reasons for the check-engine light to come on

Even though there is a wide range of issues the check-engine light can indicate, it’s helpful to know what some of the most common causes of check-engine light illumination are. These are the top 5 related issues that usually cause the check-engine light to come on:

Spark plug failure or wear
It is essential that your Audi’s spark plugs remain in constant function, otherwise you could encounter engine misfiring or other issues that can not only cause damage to your vehicle, but pose a danger to you and your passengers while driving.

Catalytic converter issues
If your catalytic converter fails, your Audi will be unable to convert the harmful gases created by your engine into milder compounds that are less damaging to the atmosphere – this often leads to failed emissions testing.

Oxygen sensor failure or malfunction
Along with working spark plugs, your engine also requires the proper amount of oxygen. As part of the emission system, the oxygen sensor determines if your engine is receiving the proper amount of oxygen for combustion.

MAF (mass airflow) sensor
Without a working MAF sensor, your engine doesn’t know how to adequately adjust fuel and oxygen ratios for optimal performance.

Basic fuel system error
The most common fuel system error that causes the check-engine light to come on is a loose or ill-fitting gas cap – quite a simple issue with a simple solution.

Why it’s important to follow up on the check-engine light

Your Audi’s check-engine light commonly indicates that there is a problem with a primary area of your car’s functioning, which is why it is essential to follow up on any concerning symptoms – especially when the check-engine light comes on. Diagnosing the issue and treating it effectively as quickly as possible can help ensure your safety and secure the value and reliability of your vehicle.

Audi Electrical Issue Repair

What are the Electrical Problems Found in an Audi

All cars require maintenance. Many decades ago, that maintenance could be done at home and revolved around oil changes, tire rotations, and brake pads. The modern vehicle comes with a few more bells and whistles, though, and sometimes these bells and whistles break down as well.

Residents of California, and especially those of Los Angeles County, CA, drive modern cars to stay cool, stay connected, and to safely get where they are going around Canoga Park, Woodland Hills, and the San Fernando Valley. Many of them drive European model cars, such as Audis, as well. If you drive an Audi or other European model cars, what kind of electrical maintenance can you expect your car to need?

Burnt Out Power Window Motor

One of the most common electrical problems in Audis is the power window motor burning out. Usually, the driver’s side front window is the first to quit because it is the one used the most often. It is not a difficult repair, but it involves removing the door panel and replacing the motor. If your power windows are failing, call Euro Plus Automotive for a quick repair.

Display Screens

Another breakdown point in the electrical system of your Audi is in the LCD screen. The entire screen does not usually fail at once, but there are often areas of the screen which burn out. The result is that it makes it difficult to read the information on the screen. Unfortunately, this is not an item which is repairable, one part of the screen at a time. Usually, to restore the function and readability of the screen, the entire LCD unit needs to be replaced.

Stuck Brake Lights

Audis occasionally suffer from a unique problem of stuck brake lights, when the brake light switch fails, and the lights will not turn off. It usually requires a professional Audi repair mechanic, but the part is easy to acquire, and the service usually takes less than 30 minutes. If your brake lights are beginning to stay on, be sure to get them checked out and repaired today to help keep you safe on the road.

Liquid Damage to Center Control

Audi R8 One engineering mishap of some Audis is that their MMI unit is located directly under the cupholders. This unit controls the navigation system, radio, entertainment, and dashboard of the vehicle. While it is not essential for merely driving, it controls all of the extra electronic perks you get in your car.

The problem of this placement, as you may guess, is that any spilled liquid has the chance of seeping into this electrical system and ruining it. Liquid damage is not a cheap fix. The best way of dealing with this is to prevent any leaks from occurring in the first place by keeping lids on your drinks and not leaving them in the car over long periods of time. If you do suffer a significant spill, bring it into Euro Plus Automotive for a quick inspection.

Battery issues

Many electrical issues result from improper battery changes, poor terminal connections, and reconnection. Some of these cars (like the A6) do not have circuit protection. Once you have altered the traces on one of the control chips you are likely to notice strange, ongoing, electrical occurrences in your car. Do not take the risk of having an untrained person change out your battery or doing it yourself. Be sure to get yourself a professional.

These issues will also occur if you try to jump start your car or use a low-end charger on it. Again, if you suspect any problems with your battery, contact Euro Plus Automotive and have it checked out by the professionals today!

Audi Electrical Problems


Your car maintenance is important, and if you have a modern car, the electrical maintenance is as extensive as the motor itself. If you have an Audi or other European cars, it is vital that you do not entrust your vehicle to just anyone. Find a professionally trained mechanic with experience working with them so you can rest assured that your car will be up and running correctly for years to come. If you live in the San Fernando Valley or Los Angeles County, CA, be sure to check in with Euro Plus Automotive.
