Audi O2 Sensor

An Audi is a sleek and innovative vehicle with intricate systems that work to provide you with high-quality performance. It also requires high-quality care. Taking care of your Audi requires a far bulkier commitment to service than the average car, but you don’t need to go to a dealership to keep it running smoothly.

To maintain that peak performance, a good car owner needs to receive regular maintenance. This includes repairing and replacing components over time as well as bringing it to a mechanic immediately when the check engine light is illuminated. It may be alarming to see the light is on, but that doesn’t have to indicate a severe issue.

Your Audi will automatically illuminate the check engine light when it has detected a problem within its onboard diagnostics system. Every Audi was designed to include a high-tech performance monitoring system with a computer and a series of sensors throughout the vehicle. If the control unit detects that the data is out of factory specifications in any way, the check engine light will flash to draw your attention to the problem. One of the more common causes can be that your oxygen sensors need replacing.

What is an oxygen sensor?

An oxygen sensor is one of the most important elements in a modern engine management system. There are two to four sensors about the size and shape of a spark plug located near the car engine’s exhaust stream. In real-time, it works with information from other sources to help determine the air-fuel ratio of a combustion engine. More simply, it calculates how much oxygen is in the exhaust and makes adjustments to the amount of fuel being used in the engine.

There are a few different reasons why oxygen sensors need replacing, but they also wear down over time just due to normal usage. The vehicle begins functioning with a delayed response and eventually fails. If you continue to use your car with damaged sensors, the engine will sustain damage while consuming far more gas than is needed.

Replacing the Oxygen Sensors in Your Audi

To replace the oxygen sensors on your own, you’ll need a jack and jack stands, an oxygen sensor socket or appropriately sized open-end wrench, an OBD II scan tool, and the replacement oxygen sensors.

Before doing anything, connect the OBD II scan to the vehicle and read the displayed codes to determine which specific oxygen sensors have failed and need to be replaced.

Once you know where the problem is, raise the vehicle on the side that will allow you access to the sensor and secure it using the jack stands.

Identify the damaged oxygen sensor and disconnect the wiring harness connector. Using an oxygen sensor socket or open-end wrench, loosen and remove the oxygen sensor. Compare the original and replacement oxygen sensors to ensure the correct fitment.

Install the replacement oxygen sensor and connect the wiring harness connector. Once the new sensor has been installed and secured, reconnect the OBD II scan tool and clear the codes. Start the vehicle and monitor your dash to see that the check engine light is no longer on.

When do I need to see a professional?

While this is often a simple replacement that you can do on your own, many people are either not comfortable doing it or do not possess the tools needed to complete it at home. If your check engine light does not turn off after the procedure or you need assistance, see an Audi-certified mechanic.
