Expert Service for Your Audi in Louisville to Replace the EGR Valve

Posted on August 26, 2021 by smikyautomowp

As an Audi owner, you may enjoy its smooth, superior performance above its many perks. You want the most knowledgeable and reputable technicians to keep your car running well. The EGR valve is a critical component of your Audi’s engine system, and because it is so important, the consequences of not replacing it when it is failing can hurt your Audi’s power and speed. Our technicians at St. Matthew’s Import Service are experts at handling any case of EGR valve replacement.

The EGR valve is responsible for constricting the harmful release of air pollutants, specifically nitrous oxide. It does this by regulating the temperature of gases through recirculation, which passes through the valve itself. As well as keeping the air around us clean, it keeps the engine from overheating. Although physically a small part, it is vital to your Audi’s health. Replacing the valve and getting preventative care will reduce the likelihood of your engine failing so that you can enjoy worry-free driving.

Why do EGR valves need to be replaced?

EGR systems filter out unnecessary pollutants from the exhaust system. This keeps excessive amounts of nitrous oxide out of the air and in cars. Over time, the EGR valve collects the product of this constant recirculation and filtering. The buildup causes the valve’s piston to become stuck and no longer able to serve its purpose.

When pollutants cause the EGR to be coated with remnants, it blocks the engine’s flow. It would be easy to mistake the engine’s breakdown as the result of a different problem. Looking out for other symptoms, such as those below, can help you pinpoint the valve’s insufficiency.

The carbon buildup on the valve can be cleaned instead of replaced. A regular trip to St. Matthew’s Import Service can accomplish this for you. We will also check the health of the EGR system so that preventative measures can be taken if necessary.

How to Know When to Replace Your Audi’s EGR Valve

Some signs of a malfunctioning EGR valve are visible and some need more investigation. Below are the most common symptoms that your car will present if the EGR valve needs cleaning or replacement:

• The smell of exhaust fumes or gasoline is hard to ignore, and the drivers behind you may stay back quite a distance if this is the case. Your EGR system may not be recirculating fumes properly, which means what is usually filtered before being expunged is now steadily coming out of your car.
• A decline in speed and performance is not something any Audi driver wants to experience. When the EGR valve is failing, the combustion chamber is not getting the amount of gas it needs to bring the acceleration to its full potential.
• Overheating engine: The EGR valve plays a significant role in lowering the engine’s temperature so that the car can run without hindrances like weak acceleration. An overheating engine can also lead to severe damage like cracks and oil leaks and further, render your car undrivable.
• Engine knocking results from high temperatures, and if there has been no other obvious sign of a hot engine, then knocking is a strong indicator.
• Rough Idle: An unusually-rocky vibration that happens when your car is sitting idly means that your vehicle is experiencing a rough idle. Like other valves, the EGR valve’s piston requires movement to work. Often, a valve can become stuck, and rough idling happens when the EGR valve is sticking.
• Engine Warning Light: If your Audi is experiencing any of the red flags above, the EGR valve may be at fault. Your engine light could illuminate for many reasons. Always bring your Audi to us if your engine light is on, in order to resolve the issue before it becomes a costly repair.
