O2 sensors are not something most people ever think about. In fact, many people aren’t even aware of what an O2 sensor is and what it does for your Audi. Engine performance is regulated by a multitude of sensors to ensure that it is running as per the manufacturer standard. The O2 sensor does exactly what its name suggests: it monitors the levels of oxygen in the fuel.
The sensor is intuitive and can tell when the fuel is running too rich or too lean, and that message is sent to the engine to adjust the mixture. Usually, we don’t have to worry about what the O2 sensor is doing, as it typically handles its job without interference or a need for maintenance. However, if the sensor begins to show signs of malfunction, it could mean there is a greater problem that needs your attention.
Our cars are basically mobile computers that regulate mechanical functions as we go about our daily commute. Because they have intuitive design, they let you know when something isn’t working properly with warning signs of malfunction. Because the O2 sensor isn’t something the average car owner has to worry about, here are a few signs to look out for so that you know when it’s time to take your Audi to a mechanic.
Your check engine light is the warning sign for a lot of different malfunctions in your Audi. It can mean anything from low oil to an electrical misfire. If you see your check engine light illuminate, you should visit a trained service mechanic immediately. Oftentimes, they will diagnose the warning light cause at no cost to you so you can know exactly what is happening with your vehicle. Because your check engine light can signal something serious, you don’t want to ignore it for long periods of time. It is a warning to you that something is malfunctioning, and if left unchecked, it could lead to far worse damage that will be more expensive to fix.
If your Audi is rattling, bouncing, or lurching while you’re driving, you are seeing signs of a rough idle or a beginning stall. Idling and stalling can be caused by several issues, but they can reduce your vehicle’s performance and make you vulnerable to accidents if it happens in the middle of the road. If your car is showing these signs, it could mean there is a failure of the O2 sensor and should be looked at immediately.
If the issue is with your O2 sensor specifically, you will notice an increase in fuel consumption. Because the sensor keeps an eye on how your fuel is running, if it is malfunctioning, it can’t communicate with the other parts of your vehicle to adjust the air-to-fuel mixer. It could run rich or lean.
State regulators will not pass your car when it comes time for inspection if your O2 sensor is malfunctioning. It regulates the emissions your car is expelling into the environment and those around you. Also, without it being able to help regulate those emissions, your car will start running rougher and your fuel economy will drastically drop. This can cause other components to wear and begin to overheat and fail over time. If you notice any of these issues, you should see a mechanic you trust as soon as possible to rectify the problem and save your car from far more expensive and dangerous damage.
