Where You Should Go to Repair Your Audi’s Engine Misfire in Pinevilleby Dutch Silverstein March 30, 2020
Audi has spent decades refining their vehicles to the point of excellence, and this includes their powerful engine. Known to give drivers high-performance and power, with the right care and maintenance, an Audi engine can provide excellent driving experiences for many years. However, given time and mileage, even the most well-crafted engines can start to develop problems. The most common issue that an engine system can develop are misfires. Let’s take a look at why this happens and where you should go to resolve the issue.
Reasons Behind Engine Misfires
Your Audi’s combustion engine follows a 4-stroke (or four-step) combustion cycle. The four stages are intake, compression, power, and exhaust. These occur over and over in a cycle as you drive. If any of these steps do not perform correctly or are prevented from occurring, then the result will be an engine misfire.
Types of Engine Misfires
The type of misfire your Audi experiences depends upon what has occurred inside the engine to prevent combustion from happening correctly. If one of the moving parts of the engine develops a problem, such as the pistons, then you’re Audi will experience a mechanical misfire. However, if the flow of air or fuel to the engine’s combustion chamber becomes inhibited, then a lean misfire will occur. Finally, if the air and fuel mixture inside the combustion chamber cannot be ignited, then the result will be an ignition misfire.
Types of Part Failure that Cause Misfires
Several parts in your engine system can result in misfires. The most common problem-parts include:
Your spark plugs are the part of your Audi,Audi Engine Misfire aside from the wheels, that take the most consistent wear as you drive. The spark plugs are placed in pairs and are set apart at a specific distance. This distance is just enough for a highly-charged spark of electricity to jump from one plug to another. This is what is used to ignite the fuel in the engine. However, this powerful jolt of electricity chips away at the metal surface of the plugs. Over time, this will widen the gap to the point where the spark is no longer able to reliably jump between the 2 plugs. This is when ignition misfire happens.
Fuel injectors are needed to distribute the precise amount of fuel needed to balance the amount of air entering the engine. However, over time, the injectors can get clogged up by the contaminants naturally present in the gas. While higher-quality gas tends to have less contaminants, no fuel is ever wholly free from sediment or microscopic debris. This is why maintaining the various filters inside your engine are important, as these can help trap the majority of contaminants that could reach the fuel injectors. However, given enough time and the failure of filters, the fuel injectors can become clogged. This negatively affects the amount of fuel that can enter the engine, throwing off the balance of air and fuel and causing lean misfires.
If your engine isn’t correctly maintained, or early warning signs have been ignored, a leaky head gasket may blow. In the early stages when leaks occur, the cylinders are not able to reach the maximum compression needed to pressurize the air and fuel mixture inside the combustion chamber for optimal ignition. This is an example of mechanical misfires. This can also contribute to general rough idling and reduced performance.
How Engine Misfires are Fixed
As there are a myriad of causes for engine misfire, there are also so many ways in which misfires are also repaired. Because of this, and the cost of your engine as a whole, if you’re not experienced or have any doubt in what you are doing, you shouldn’t attempt DIY engine repairs. An experienced mechanic will be able to pinpoint issues through experience, and they will methodically work through more obscure issues. This will help ensure that not only will your problem be resolved correctly, but that the overall health of your engine is safeguarded also.
