Audi has been a dominant force in the luxury car industry, even as a relative newcomer forming as the company known today only six decades ago. These cars are built for durability, safety, and a luxurious ride. Although they will keep you on the road for years to come across thousands of miles, it only comes from proper upkeep and maintenance.
As with any aspect of maintenance, anticipating problems and keeping up routine work is safer and cheaper than waiting until something is already worn out and broken, which often leads to damage to other parts of the vehicle. There are some common issues and routine services to keep your luxury vehicle on the road and out of the shop.
What does the EGR Valve do?
Through some complex chemical reactions between the fuel, oxygen, and combustion of the engine, your EGR valve works to keep the cylinders cool and functioning optimally. There are some clear symptoms to look out for to tell if your EGR valve is failing, and some options for what to do if this is the issue.
- Performance while driving: Every part serves its own purpose. Because of this delicate balance, if the cylinders are not being cooled properly, performance of the vehicle will begin to suffer. In many ways, this is both good and bad. As the driver, you will notice any relatively small changes in driving. The difficulty is that as the check engine light does not share exact information on what’s wrong, this issue could be a sign of any number of issues. That is why it is so important to bring your vehicle to a certified technician as soon as a problem arises.
- Difficulty idling: A specific problem that can help pinpoint the EGR Valve as the issue is if the car experiences significant change in idling. When a car is idling there are many fewer moving and operating parts so a roughness in operation can be seen or heard. The cylinders, where pistons are housed and fire thousands of times per minute, have very tight tolerances. The temperature is critical because as metals change in temperature they expand and contract. Though the engine will continue operating for some time after the valve has sustained damage, if not addressed, it will only lead to further damage to other parts in the engine.
- Check Engine Code: The best way to know the EGR Valve needs to be cleaned or replaced is that there are check engine light codes for most issues. The car’s computer chip should sense the problem and be able to throw the correct code. At this point it is best for the driver and vehicle to have it looked at by a professional because they can check the codes and look at the engine itself, to save you the time, money, and guesswork.
Change or Repair?
With an even smaller membrane inside this already relatively small part, there are a couple options to approach sustained damage. Sometimes the valve can be simply sticking or not closing as it should be. In this case, the valve can be cleaned and you can keep on driving.
Due to the critical role this plays if it is already clogging and the part needs to be removed to clean anyway, many drivers make the choice to have it replaced and not have to worry about going in to clean it again some months down the road.
