When purchasing an Audi, it is important that you are aware of potential problems that may arise as the car ages and wear and tear begins to take its toll. One such problem seems to be with the Exhaust Gas Recirculation (EGR) valve. This valve is responsible for ensuring that your car is fuel-efficient and that the environment is protected.

How does an EGR valve work?

The EGR saves fuel by rerouting part of the unused fuel back into the engine so that it can be reused before being expelled out of your automobile. It also minimizes hazardous gases in the atmosphere.

The EGR valve initiates a chemical process in the intake system that burns and converts the gas to a less-toxic form by recirculating gases back into the engine of your Audi.

When should you replace your EGR valve?

Audi suggests replacing your EGR valve after 50,000 miles. Changing it at this interval will help to avert total failure when driving your automobile. Other factors might shorten your Audi’s EGR valve’s lifespan.

Let’s take a closer look at the warning signs that could lead to sudden failure so that you can keep your automobile operating smoothly before the 50,000-mile milestone:

  • Increased fuel consumption: When your Audi’s EGR valve fails, it consumes far more fuel than what it needs to run. When your vehicle’s system detects a need for additional fuel, it sends the signal to add more. What it isn’t aware of yet is that there is an issue causing this excessive fuel requirement.
  • Check engine light: Whenever the system detects that there is a problem with your EGR valve, it will display the check engine light.
  • Engine knock: A faulty EGR valve prevents the byproducts of nitrogen gas from being converted into less hazardous gases. These more dangerous gases could lead to knocking sounds in your engine.
  • Poor performance: Without a properly-functioning EGR valve, your Audi will perform poorly during acceleration and as you drive on the highway.

Causes of EGR Valve Failure

Typically, an EGR valve malfunctions when specks of dirt and grime accumulate inside it. It’s normal for some carbon buildup to occur over time, but when this buildup is excess, it could mean that something has gone wrong. Here are a few reasons why impurities accumulate within an EGR valve.

  • Faulty or non-existent air filter: To perform well, your Audi makes use of air pumped into it. All of the contaminants that come with this air are not needed, and that is where the use of an air filter comes in. An air filter is intended to keep these air contaminants out of the engine. When you use a cheap or defective filter, impurities will be allowed to flow through. When this happens, they go straight into the EGR valve to cause a blockage or damage.
  • Intake Leaks: If your filter is leaking, it might cause problems with the intake system. To allow sufficient air to flow through the filter, the system must be sealed. Any leakage beneath the air filter will allow debris to slip through.
  • Vacuum leaks: Vacuum leaks act in the same manner as a leaking intake system, allowing some air to bypass the filter.

The EGR valve is important to the overall performance of your vehicle and is also environmentally friendly. As a result, if you observe any of the above-mentioned problems, it is time to take your Audi in for service.

EGR Valve Replacement

The exhaust system on your Audi and most other vehicles might be costly to replace. However, replacing an EGR valve is not incredibly expensive. If a person with limited experience in Audi technology performs the repair, they risk causing more damage to the whole exhaust system.

If you want a professional to replace your EGR valve, only ASE-certified technicians who are familiar with the Audi engine are required to do the repair work. Also, ensure that they have the right equipment to correctly analyze your EGR valve problem in order to determine whether the repair was even necessary in the first place.
