Audi is at the forefront of motoring innovations. All modern high-performance cars rely greatly on a variety of sensors to ensure the driving experience they offer their drivers is second to none. There are sensors throughout every system of your car from air flow sensor, temperature sensors, and more. These sensors help to precisely manage the overall performance of your car, guaranteeing excellence in performance while driving time after time.
One of the most essential sensors in your Audi is the oxygen sensor. Also known as the O2 sensor, this part is integral to the overall health and operation of your vehicle. In this article, we will look more closely at your oxygen sensor, find out what it is, what it does, and also discuss some common signs and symptoms of failure.
What does the oxygen sensor do?
The oxygen sensor is found inside the exhaust system of your Audi. Its purpose is to examine the chemical makeup of your vehicle’s exhaust emissions. It provides this information to your Audi’s OBD (onboard computer) which is then used to make adjustments to guarantee optimal engine performance.
The oxygen sensor helps ensure peak engine performance, as it helps make sure that the air-to-fuel ratio inside the engine is perfect, meaning that combustion is steady and perfect every time. It mainly helps ensure this by giving the OBD data to make miniscule adjustments that make a big difference to your vehicle’s performance and safety.
Signs and Symptoms of a Failing Oxygen Sensor
It is important that drivers are aware of some of the most common signs and symptoms of part failure. Spotting warning signs early can help preserve the overall health of your vehicle as well as save you money by avoiding extensive repairs. Below are some of the most common signs of O2 sensor failure.
1. Poor Engine Performance
To operate at its very best, you engine needs every part of your car to be firing on all cylinders. Just one part failure can start to take a toll on your engine, and in the case of oxygen sensor failure, it can cause your engine to misfire more frequently as well as idle roughly and stall more often.
2. Low Fuel Economy
High-performance vehicles often have impressive fuel economy due to the variety of delicate sensors and measuring tools they use to ensure exact amounts of fuel are used. If the oxygen sensor starts to fail, then your car is likely to use more fuel, otherwise known as running rich, resulting in lowered fuel economy.
3. Check Engine Light
The check engine light is a warning indicator on your dashboard that will illuminate if the onboard computer senses an issue with the engine or its related systems. If the O2 sensor is the cause of the illumination, then the OBD will show specific error codes to the diagnostic tools of your mechanic, who will be able to interpret these codes and offer the proper repairs.
Preventing Oxygen Sensor Failure
The best way that any driver can prevent any part failure is to make sure they follow a comprehensive maintenance routine and seek yearly servicing from an expert mechanic. It is no different when it comes to caring for your O2 sensor. Taking your Audi in for regular maintenance by experienced professionals will ensure that all issues are dealt with in a timely manner and all parts are kept in peak running order. This benefits you, as it ensures you have the very best driving experience your car can offer.
Of course, problems can arise quite suddenly, even with good maintenance practices, and when this happens, you should seek diagnostic work and repairs from a professional mechanic as soon as possible.
