Where to Go in Bellingham to Replace the Oxygen Sensor in an Audi

Posted on July 15, 2021 by Keith Cox
Audi Oxygen Sensor

A common issue we see at Keith Cox Audubon is failed oxygen sensors in Audis. As Audi adds more sensors and technology to newer models, we see more sensor failure.

Oxygen sensors are found in the exhaust system and are used to measure oxygen levels. The information they gather helps determine the proper air-to-fuel ratio your Audi needs to function properly. If the oxygen sensor fails, your engine can get too much oxygen or not enough. This will decrease the performance of your Audi and increase emissions. It puts your engine and the catalytic converter at risk of experiencing damage.

Symptoms of a Bad Oxygen Sensor in Your Audi

If your Audi has a bad oxygen sensor, it needs to be replaced immediately. The sensor is critical for engine performance, fuel economy, and improved emissions. Continued driving with a failing oxygen sensor can cause additional damage and higher service bills. If you have an older Audi, you should have the oxygen sensors tested.

Below are some common symptoms of a bad oxygen sensor:

  • Rough Idle: When the oxygen sensor begins to fail, you may experience rough idling. This rough idle happens because your engine is not getting the proper air-to-fuel ratio. Your Audi may also stall, hesitate, or backfire.
  • Rotten Egg Smell: If there is a smell of rotten eggs coming from your Audi, there is an issue with the fuel system. This could be due to a failing oxygen sensor.
  • Reduced Gas Mileage: When the oxygen sensor fails, your Audi will begin to burn more fuel. This is because your engine is not getting the proper air/fuel ratio. If you are filling up your gas tank more often than usual, you may have a faulty oxygen sensor.
  • Illuminated Check-Engine Light: The check-engine light is there to tell you when the computer has recognized a problem. If the oxygen sensor is experiencing issues, it should trigger the warning light. There are countless problems that can trigger this indicator. If your light is illuminated, have us perform a diagnostic scan to find the cause.
  • Emission Test Failed: Your Audi may not show any symptoms of a faulty oxygen sensor. The only way you may find out there is a problem is when your vehicle fails an emission test. There are several states that require the test. This test helps to keep cars off the road that are producing too much carbon emissions.

When to Replace the Oxygen Sensor

Oxygen sensors are not a component of the vehicle that are replaced during regular maintenance. However, they do wear out and need to be replaced from time to time. We often recommend that you have the sensors replaced if your vehicle is 15 years or older or every 60,000 to 90,000 miles. When you have the sensor replaced, you can see an increase in fuel mileage and cut down pollution.
