Why Should You Replace the Oxygen Sensor in Your Audi?

Why Should You Replace the Oxygen Sensor in Your Audi?

Audi cars require ongoing, specialized are in order to run optimally and function at their best. However, even with the best quality care, issues can still arise prematurely. One issue that has been documented to prematurely occur is oxygen sensor failure. The oxygen sensor in your Audi plays a critical function for your engine’s performance. When the oxygen sensor begins failing, you’ll notice specific symptoms that can be troubling. In this article, we’ll go over what the oxygen sensor does for your Audi, the symptoms you should be on the lookout for, and what you can do next to remedy the problem.

What Does the Oxygen Sensor Do for Your Audi?

Oxygen sensors are an important factor for determining the proper fuel-to-air ratio your car uses for combustion processes. It measures the amount of oxygen in the exhaust to determine if the appropriate ratio is being used for combustion, then it sends the information to the car’s powertrain control module to adjust the amount of fuel dispersed into the engine. A failing oxygen sensor will certainly affect your Audi’s performance, but it can also have a serious lasting effect on the engine and other components related to the oxygen sensor, like the timing and exhaust systems.

Signs that Your Oxygen Sensor Needs to Be Replaced

As with any car malfunction or issue, it is important to pay attention to how your car is behaving so you can report the symptoms to Myour Audi automotive specialist. Some symptoms are more troubling than others, but it’s critical to address the problem before symptoms worsen and significant damage is done. These are the most common signs that your oxygen sensor needs to be replaced:

Check-Engine Light

Any time the check-engine light comes on it causes a surge of fear in the driver. The check-engine light becomes illuminated under specific circumstances, which can include oxygen sensor failure. Your Audi technician will be able to read the codes emitted by your car’s computer, follow the clues to properly diagnose the problem, and then devise a treatment plan that could likely include replacing your oxygen sensor.

Performance Differences

Performance problems are the most salient reason why Audi drivers report issues with the oxygen sensor—probably because they’re pretty serious. These are just a few performance differences you might notice in your own Audi if the oxygen sensor fails:

Engine Misfiring

This symptom is not only highly inconvenient, but dangerous and downright scary. If you experience engine misfiring, your check-engine light may also illuminate. It’s critical that you bring your car in for an inspection right away.

Rough Idling

Rough idling isn’t something we all notice behind the wheel, as it’s not really a “performance” issue per se; however, if you begin noticing any vibrating, shaking, or odd noises coming from your car as it idles, the problem could be related to a faulty oxygen sensor, as the engine isn’t receiving the proper amounts of fuel and oxygen.

Why It’s Critical to Hire an Audi Specialist

Vehicles that were made in the past decade or so are made with durable parts, but still require servicing and replacement from time-to-time. Depending on the type of vehicle you drive, your oxygen sensor will need to be replaced somewhere between the 60k-90k-mile mark. It’s best to follow your specific vehicle’s maintenance schedule recommended by the manufacturer, but in collaboration with an Audi specialist who has extensive knowledge and experience detecting and repairing common Audi issues.
