5 Signs You Need to Replace Your Audi’s Oxygen Sensor from Certified Mechanics in Suwanee

All modern cars are coming equipped with many high-end features that make driving them a real pleasure & your Audi is not an exemption. In fact, Audi is one of the most popular luxury cars that one gets to see frequently on the roads of Suwanee, GA.

One such extraordinary feature in your Audi is the oxygen sensor or O2 sensor as it is popularly called. There are many sensors in your car that monitor the functioning of the vital parts & the O2 sensor keeps a tab on the air/fuel mixture of your vehicle which is essential for the efficient combustion process.

Whenever the oxygen sensor malfunctions, you are going to face several issues in your car because it directly affects the combustion process in the engine. Here in this article, we will discuss the top 5 signs associated with O2 sensor failure in your Audi so that you can immediately replace it.

Emissions Test Failure

One of the prominent signs that is associated with oxygen sensor failure in your car is the failure of the emission tests that are conducted before completing one’s registration process. The primary role of the oxygen sensor in your vehicle is to reduce the emissions coming out of your car by regulating the air/fuel mixture.

The oxygen sensor gathers information about the air/fuel mixture and then relays this information to the engine control unit (ECU) of your car. The information used by the ECU is then used for regulating the flow of fuel inside the combustion chamber.

This helps in the smooth running of your car as the engine gets an adequate amount of fuel based on the air intake. However, a faulty O2 sensor often leads to your car running either lean or rich. This is when you are going to fail the emission test continuously & it is best to replace the oxygen sensor.

Engine Issues

Whenever there is anything wrong with the functioning of the oxygen sensor in your vehicle, then it has a direct bearing on the functioning of the engine. A faulty O2 sensor will disturb the air/fuel mixture of your car and this will give rise to several issues in your high-end car.

Due to an improper air/fuel ratio, the engine timing will go haywire and the combustion process is going to get affected. This is when you are going to experience frequent misfiring, rough idling, and engine stalling when starting your car.

Moreover, you might also experience a drop in the performance of your car as the engine will struggle to keep up with the demand for more power. You must not waste any time and take your luxury car to an Audi specialist who can accurately diagnose the problem in your vehicle.

Decreased Gas Mileage

Now, most luxury car drivers won’t be looking at their fuel gauge often as high-end cars are considered a bit low on miles per gallon. However, there is a great misconception when it comes to decreased gas mileage. No matter what your car will be having a constant gas mileage based on your city or highway driving.

However, when you see frequent fluctuations in these miles per gallon and a drastic drop in the gas mileage of your car without any reason, then you must seat up and take notice. Most of the time this indicates underlying issues that need to be rectified immediately & a bad oxygen sensor also cannot be ruled out altogether.

Pungent Smell

Among the various signs that you are going to witness in your car whenever the oxygen sensor fails, experiencing a pungent smell is quite common. Most of the time when the O2 sensor goes bad it leads to a rotten egg-like smell inside the cabin of your car.

This smell is caused due to the presence of an excess amount of fuel in the engine. In addition to the smell, you might also get to see excess black smoke coming out of the exhaust of your car. All these things point toward the failure of the oxygen sensor in your car.

Check Engine Light

The check engine light located on the dashboard of your car is responsible for alerting you whenever there is something wrong in your vehicle. The illumination of the check engine light can be caused due to failure of the oxygen sensor.

However, the check engine light can come on due to various other issues and a certified mechanic is the only person who will be able to diagnose the root cause behind the warning light illumination.

Finally

The above-discussed factors are some of the signs that you are going to experience whenever the oxygen sensor of your Audi goes bad. Most of the time the premature failure of the oxygen sensor can be avoided if you are proactive in maintaining your high-end car as per the manufacturer-recommended maintenance schedule.
