When you purchase an Audi it is helpful to be aware of issues that may develop as the years go on and wear and tear may begin to take a toll. One such issue has to do with the EGR valve. This valve plays a crucial role in ensuring that your Audi remains fuel-efficient and the environment remains protected.

The Purpose of the EGR Valve

As your Audi runs, gases are created by the engine. Normally, these gases are released out of the vehicle through the exhaust pipe and into the environment. Now more than ever, vehicle makers are attempting to reduce the amount of nitrogen oxide gases that are being emitted. The way that Audi does this is by having an EGR valve.

The EGR system, Exhaust Gas Recirculation system, is responsible for redirecting exhaust gases back into the engine to be reused instead of immediately being let out into the atmosphere. The EGR valve is what is in place to ensure that those gases are being circulated back to the engine.

When there is an issue with the EGR valve, your Audi will start to release a significant amount of gases into the environment. This should be quickly prevented to ensure that your Audi is not negatively affecting the environment. A properly-functioning valve will also ensure good fuel efficiency, which means less expense.

Signs of a Failed EGR Valve

Knowing and being able to recognize the signs of a failed EGR valve is how you remain vigilant about the overall health of your Audi. These signs can sometimes correlate with other parts or issues in your vehicle. The signs below will alert you to the need for proper maintenance and an inspection of the EGR valve.

• One sign to look for is a compromised fuel economy. The EGR system helps your Audi run efficiently because it is recycling gases. These recycled gases allow your Audi to use less fuel. If the EGR valve needs to be replaced, then more fuel will be used. The excess fuel will be used in an inefficient way as your Audi was meant to function with the EGR system fully intact. You will notice that there is something wrong with the fuel economy when you frequently have to stop at the gas station to fill up.
• Another sign is rough running and idling. The engine of your Audi needs the gases that would normally be expelled for its overall function. This is the way that your Audi was designed, which is why there is an EGR valve in place. Without the nitrogen oxide gases re-circulating through the engine, the engine becomes unbalanced. This imbalance leads to a rough running engine. You will feel excessive vibrations as you drive and when you sit idle at a stoplight.
• One last sign that you should be aware of is the check engine light. Your Audi was designed to be a smart vehicle, so it has countless sensors that are constantly reporting back to the computer. If the computer receives notice that the EGR valve is malfunctioning or has completely failed, you will be alerted via the dashboard. There is not a specific light for the EGR valve, so the check engine light will illuminate. As stated previously, this sign could apply for other issues, but if you see this in conjunction with one of the other signs, then it is most likely an issue with the EGR valve.
