Audis are known for their reliability, but are prone to wear-and-tear over time just as any other vehicle. As an Audi owner, you’ll want to stay on top of any issues, even minor ones, to ensure your vehicle’s longevity.
Minor issues can and will lead to major issues if not dealt with in a timely manner. One such minor issue you may encounter is an oxygen sensor failure. Let’s discuss the role of an oxygen sensor in your Audi, signs of a faulty oxygen sensor, and what to do when your oxygen sensor needs replaced.
The oxygen sensor in your Audi monitors the oxygen in the exhaust after fuel has been burned. Your car’s combustion process cannot work properly without it. The oxygen sensor helps regulate your fuel mileage and is responsible for your vehicle’s performance. An oxygen sensor’s role in regulating your fuel mileage is important because without it, your Audi will run at lower fuel mileage, which results in more frequent trips to the gas station. Lower fuel mileage also contributes to increased air pollution, so not only do oxygen sensors help your car run efficiently, they help protect the environment, too.
When oxygen sensors go bad, it is usually caused by one of two reasons: the sensor is wearing out after years of use or it has been contaminated.
Oxygen sensors are fairly cheap to fix and definitely cheaper than having to fill up your gas tank more than what is necessary. The oxygen sensor lets your vehicle’s computer know when the oxygen level isn’t correct and when an adjustment is needed.
A faulty oxygen sensor cannot provide an accurate air-to-fuel ratio, and will signal to your Audi usually in the form of a check engine light that something is amiss. While a bad oxygen sensor might not stop you from getting from point A to point B, letting the problem persist over time could lead to engine damage. If you suspect a problem with your Audi, it is much cheaper to have it examined as soon as possible and will spare you from future headaches in the long run.
If you’re experiencing suspicious activity with your Audi, a failing oxygen sensor may be to blame. Here are the key signs there’s a problem with your oxygen sensor:
If you find yourself making more frequent visits to the gas station, your vehicle is receiving poor gas mileage, which is one of the key signs your oxygen sensor is on the fritz.
A rough idle when starting your car or stopping at stop lights is a sign your vehicle is in trouble. An oxygen sensor’s output helps control engine timing, combustion intervals and the air-to-fuel ratio. If the sensor is going bad, these engine functions cannot work as they should, which leads to the rough idle or misfires you may be experiencing.
Because the oxygen sensor’s job is to regulate the air-to-fuel ratio to your engine, a problem with the sensor will cause increased vehicle emissions. It could result in lean or rich fuel-injection delivery. All lead to improper engine combustion and increased emissions.
The most obvious sign your Audi needs maintenance or repair is the check engine light turning on. When this happens, you should consult your trusted Audi service and repair center as soon as possible.

Keeping your vehicle in working order is all about routine maintenance, which should be performed to keep a vehicle as reliable as Mercedes driving as it should. For any driver, it can be worrying to see problems emerge under the hood of your car. Despite this, rest assured knowing that most problems can be quickly and successfully handled by professionals.
On that note, there are more serious issues that can arise under the hood, such as an air suspension failure. If you believe or know this has happened to your Mercedes, it’s best to take your car in right away so that the problem is not made worse. Always trust a certified professional to fix problems on your car, and keep an eye out for some of the common signs that something has gone wrong with your air suspension system.
To actually understand who it is important to get your air suspension fixed when problems arise, you need to first understand what the air suspension system does. Doing so will allow you to see the importance and reasoning behind getting it fixed. In short, an air suspension system is a reason you are allowed to drive your car comfortably.
Originally used mainly in the trucking industry, an air suspension system is still relatively new to standard cars. The air suspension system used in Mercedes’s powerful cars helps to ensure a smooth and non-bumpy ride by using a controlled method.
In older cars, a vehicle’s suspension system used coil springs to support the vehicle. As you may have guessed, air springs are used in Mercedes vehicles in place of the traditional spring.
These air springs are tough rubber plastic bags that get inflated to a certain pressure and height when demanded. This action, powered by sensors and electronic controls, allows your Mercedes vehicle to adjust its height electronically depending on where you are driving your vehicle.
The airbags that take the place of the coil springs are also responsible for absorbing a fair amount of the impact that may be experienced from driving on the road. If there are problems with the air suspension system, they are likely to be noticed quickly as the ride may become far bumpier. Any problems that are noticed should immediately be taken care of as soon as possible to ensure no further problems develop.
Fortunately, given the importance of the air suspension system, there are a number of signs to watch out for that will indicate when the system may be having problems. Any of the following signs should be taken seriously and used as cause to take your vehicle into the shop.
Each air spring in the system on your Mercedes is independent. Even though it is unlikely, if the rubber casing of the airbag has a rip and cannot inflate, you may notice your car tilt to one side if you try to adjust the height of your vehicle. This is a great indicator that one of the air springs in the system is not working.
If you attempt to change the height on your Mercedes to no avail, it’s possible that an electrical problem is stopping the air springs from inflating. It’s also worth noting that trying to change the height on your vehicle and the height being wrong can also occur if the sensors that tell the air springs to quit inflating stop working. Regardless, this is a major sign that something is wrong.
As mentioned, the air springs help the shocks on your car by absorbing a large number of impact sensations from the road. If the air suspension system fails in your Mercedes, you may notice that the ride becomes a lot bumpier and you begin to feel more sensations from the road.
