The oxygen sensor in your Audi plays a crucial role in the smooth running and better performance of the car. However, issues with the functioning of the oxygen sensor can adversely affect the smooth running and better performance of your Audi and will leave you disappointed.
There are several factors that can affect the functioning of the O2 sensor in your Audi and it is pertinent to address these factors. Here in this article, we will discuss the reasons behind O2 sensor failure & tips to prevent the problem.
- Dirty Fuel
- Overheated Engine
- Oil & Coolant Leaks
- Electrical Faults
Dirty Fuel
One of the leading reasons behind the failure of the oxygen sensor in your high-end car is related to the type of fuel you are using in your vehicle. Most of the time it is seen that Audi owners who encounter oxygen sensor failure in their cars use the general fuel that is available in the filling stations.
This low-grade fuel is filled with sulfur, lead, and silicone and these contaminants take a toll on the functioning of the oxygen sensor of your luxury car. The contaminants present in the fuel accumulate on the sensor and this hampers their ability to measure the oxygen levels properly.
One of the best ways to prevent the problem from occurring is by opting for high-quality fuel for your Audi. Besides that, you must desist from using fuel additives in your Audi unless asked specifically by the manufacturer to use them & you must also regularly clean your fuel system to make it free from any contaminants that might accumulate on the sensor & affect its functioning.
Overheated Engine
Another prominent factor behind the malfunctioning of the O2 sensor in your Audi is tied to excess heat being produced by the engine during the combustion process. The surplus heat produced by the engine can adversely affect the oxygen sensor of your car.
The heat produced due to the internal combustion process of your car affects the internal components of the sensor and this is when the oxygen sensor goes bad. The continuous exposure to excess temperature from the engine is considered harmful for any component under the hood including the oxygen sensor.
The heat produced due to the internal combustion engine needs to be kept at an optimum level all the time and the engine cooling system is responsible for the job. You need to keep a tab on the functioning of the cooling system & if any component acts up then you should get in touch with an Audi specialist immediately so that the issue is addressed before your O2 sensor gives up.
Oil & Coolant Leaks
The oil and coolant in your high-end car play a stellar role in the smooth running and better performance of your car. Generally, it is observed that leaking fluids when they come in contact with any other parts of the car adversely affect their functioning and the same thing happens in the case of the O2 sensor as well.
At times, it is seen that oil and coolant leaks when they get in touch with your O2 sensor will cause the sensor to malfunction and this is a situation you must guard against. There are several instances where the O2 sensor in Audis is damaged due to coming in contact with leaking oil and coolant.
The coolant or oil leaks out of worn-out gaskets and after your Audi picks up miles over the years, the seals and gaskets start to wear out and this is when you experience oil and coolant leaks from your car and the best way to prevent it from affecting your O2 sensor is by replacing the worn-out seals & gaskets as soon as possible.
Electrical Faults
Often it is observed that electrical problems like damaged wiring or bad connections do affect the functioning of the oxygen sensor in Audi. The O2 sensor is responsible for transmitting data to the engine control unit (ECU) and any issues with the transmission of the signal can play spoilsport with the functioning of the O2 sensor.
The best way to deal with the problem is by staying proactive in terms of regular inspection and maintenance of the electrical connections connecting your sensor with the rest of the car.
