When the check engine light comes on, it could indicate that anything from a minor fix to a large repair is needed. Most drivers find this stressful. Not to worry. In this article, we will cover some important information about your Audi’s check engine light, as well as what to do and where to go when it comes on.

Is it safe to drive when the check engine light comes on?

Since you will not know what is wrong with your Audi straight away, you are probably wondering if it is still safe to drive once the check engine light comes on.

This question does not have a single answer, as whether or not your vehicle is still safe to drive depends on the severity of the problem. However, you should be alright to keep driving to a repair shop, unless you notice any distinct changes in your Audi’s performance. If that happens, this problem is most likely serious.

Common Causes of the Check Engine Light Illuminating

Although the amount of reasons for the check engine light to come on are basically endless, there are a few very common causes that very well might be your underlying issue. While your Audi’s check engine light may be on due to one of the following reasons, it is important to schedule an appointment with a skilled service technician so they can properly identify and solve the problem.

Faulty Oxygen Sensor

If you have a faulty oxygen sensor, this can decrease the efficiency of your mileage and damage your spark plugs or even the catalytic converter. The oxygen sensor usually sends information about the amounts of air and fuel that enter the engine to the Audi’s computer. Not only will your check engine light come on, your vehicle will probably fail an emissions test if the oxygen sensor has gone bad.

Old Spark Plugs

Spark plugs or plug wires must be replaced every so often. These parts ignite the combined air and fuel in the combustion chamber, which is what makes the pistons move so your vehicle’s engine can run properly. When the spark plugs or plug wires are worn out, your Audi will perform noticeably poorly and at reduced power. The engine may have trouble running or even starting, and extensive use of old plugs can damage other engine parts.

Damaged or Loose Gas Cap

One of the simplest causes of the check engine light coming on is a damaged, missing, or loose gas cap. The gas cap keeps the fuel sealed in the system and keeps the pressure in the fuel tank even. If something happens to this cap, your Audi will lose gas via evaporation, and your mileage will decrease. The check engine light will probably come on right after you get gas if this is the problem.

Bad Catalytic Converter

The catalytic converter turns the carbon monoxide that your vehicle creates during combustion into carbon dioxide. When the catalytic converter becomes damaged, the engine will not run at peak capacity, your mileage will decrease, and your Audi will not pass an emissions test. The engine may overheat, as well.

Faulty Mass Airflow Sensor

Your Audi’s mass airflow sensor (MAF) is the part that figures out how much fuel the engine needs to run efficiently. It does this by measuring how much air enters the engine. The MAF allows your vehicle to adjust to things like a change in altitude. In addition to the check engine light, the engine may idle roughly or refuse to start if the MAF is faulty.
