What Is The Function Of EGR Valve In Audis?

by schearerswpadmin October 16, 2018

Often in life, it is the small things that make big differences. Boats can either be propelled by oars, vast sails, or great engine turbines, but the direction they go is determined by small rudders. The tiniest grain of sand in your shoe can feel like a boulder when you have a long way to walk. Similarly, there are many small parts that help keep a car going that might seem inconsequential, but in reality are imperative for your vehicle’s continued operation. This is especially true of cars known for intricate engineering, like Audis.

Your EGR Valve in your Audi is one of those small parts that makes a big difference in your vehicle. Unless you have a very old vehicle, you have one in your engine and it performs some very important tasks.

What Is An EGR Valve?
The EGR Valve is a term that refers to your Exhaust Gas Recirculation Valve, and it has two very important jobs in your Audi.

First, it monitors your exhaust system, making sure harmful gasses are not released into the atmosphere or into your car. This ensures that your Audi is able to pass the strict vehicle emission inspections, and also helps keep you and the environment safe. It does this work by controlling the temperature of combustion. High temperature combustion produces nitrous oxide and other harmful greenhouse gasses. By reducing the temperature of the combustion that powers your Audi, your EGR Valve is able to reduce the amount of excess gasses produced by your engine.

Second, it makes sure that gas is burned clearly and efficiently in the proper place, rather than combusting, or “detonating” in the engine, causing engine knock, which damages the engine.

What Kind Of Signs Show That Your EGR Valve Is Failing?
If your EGR Valve is not operating correctly, you may experience several different symptoms. You will probably notice a loss of engine power while driving. Your car may drive like it is not getting enough gas. Along with poor power, you will notice that it is not getting gas mileage the way it normally does. If you have a digital screen that monitors gas mileage, it may tell you this immediately, otherwise you will note that you have to fill the tank more often than normal. You may notice that your Audi is releasing more exhaust than normal. The final symptom of EGR Valve failure is engine ping or engine knocking.

Gas escaping through the exhaust is not a good thing for your car, but it is not an immediate safety issue. Neither is poor gas mileage. However, if gas is detonating in your engine loud enough for you to hear it (engine knocking or pinging) you need to get your Audi looked over right away. An unintentional explosion in your car is the last thing you want to have while driving.

How Do You Fix An EGR Valve?
Every EGR Valve is specifically calibrated for the individual engine it sits on. It is attached to the intake manifold most of the time and functions as a mechanical component in older vehicles, employing a vacuum connection. Newer models use an electronic mechanism, meaning that it may be an electrical malfunction causing it to fail.

Since the EGR Valve needs to be specifically calibrated, it is best left to professionals to install, repair, or recalibrate it. If you try to fix the EGR Valve yourself, you take the risk of calibrating it incorrectly, causing further engine damage and safety risk to yourself and others.

what people say about us

Excellent & timely service – keep up the great job!! =D

Excellent service. Work done on time as promised.

Just got back from having a turn signal bulb replaced… For $133… Bulb is available for $7.98 online, but the intensive training required to unscrew the old bulb and screw in the new one must have been very costly indeed. Was looking for a new place to go for service on my GTI. Got a postcard saying “you don’t have to go to the dealer” As horrible as the dealer is, I very certainly would have been much better off. Oh, and they charged me $80.00 for the bulb! I said that’s some real markup on that and they told me it was 65% markup as they bought it for $25.00… Unbelievable.

You always take good care of my daughters car. Fast reliable and honest service.

Very Professional and Through in their Work. They have my Trust in their recommendations.

Always professional. I’m a 7 year customer. I’ve had several vehicles serviced here and I’ve never had to worry that the work wasn’t done properly.

You are always very helpful to me. Had my car ready on time , the time I said needed it. No loaner cars available but so good of Rayanne and Christie to get me back and forth. Thank you so much.

Thank you for polite and professional service!

Work nicely done at a reasonable price – made recommendations for (necessary!) additional work I hadn’t considered. Left one wire disconnected, but that was promptly and properly corrected. Thanks!

Service at Schearers is always meticulous and professional. The work for which I brought my car in was done well, and an inspection of potential future problems was also undertaken, enabling me to plan for future maintenance to keep my car running smoothly. I am satisfied, as always, with the quality of work and the professionalism of everyone I encountered at Schearers.

Excellent service as usual. Work was done in a timely fashion at a reasonable price. I really like the loaner car arrangement. Mike was very nice to schedule service on the same day and get the necessary parts quickly. Samantha provided a coupon from the internet. Thanks

Friendly service and fair pricing.

Very personable owner/ family. Made us feel comfortable. Explained everything that was necessary for our car upkeep. Prices better than other foreign car dealerships. Car was completed in a timely manner. Will recommend to friends. Thank you

I wish I had found them earlier! Great company and very talented group of mechanics, specializing in German cars. They do excellent work and you’ll save a lot of money over the dealer.

Great service. I would recommend this service center to every one. Very professional and courteous. Always get the job done right.

Polite, helpful staff and professional service always!

Great experience! From the first call I made and spoke with Kristy to Mike walking me through and explaining what he was going to do. Mike also did an evaluation and let me know what to expect regarding services my car will need in the future. Exceptional customer service from beginning to end, including Samantha taking my payment. I told Mike, I am a customer for life! Well done Scherrers!! Jim Rowlands

The headlight lens cleaning was great. Thanks for suggesting.

Tom and the team deliver again! There is a reason we come back for our fleet of cars, excellent, trustworthy service with a personal touch. Keep up the great work.

Great Professional service!! I originaly contacted Schearer’s to get an estimate for my bmw M3 oil pan replacement because the threads were stripped.

Shearer’s yet again provided exceptional service! I am always informed of any maintenance requirements, reasons for, and associated costs before any actions are taken. They offered flexibility for returning home while the work was done in terms of a loaner car or ride. Everyone with whom I spoke was knowledgeable, courteous, and supportive. I highly recommend Shearer’s to service your car!

Always very nice and accommodating being that I live in Vermont. Will definitely have them maintain my sons car for the next 2 years while he attends school in PA.

Incredible service at a great price. I totally trust the Schearer’s Team!
