The Importance of EGR Valve in a Volkswagen by Experts of Tempeby admin January 25, 2021
In addition to being versatile and reliable vehicles, Volkswagens are well-known for becoming increasingly more environmentally friendly. One component that has helped with this process is the exhaust gas recirculation (EGR) valve. Not only does this valve help your vehicle function more smoothly, but it also reduces the emissions released into the atmosphere. So, the EGR valve is an important part of your Volkswagen’s engine that should definitely receive proper care.
Purpose of the EGR Valve
As stated above, the EGR valve is primarily responsible for reducing the emissions that your Volkswagen releases into the environment. In order to do this, it opens when the engine is functioning, thus allowing the rest of the EGR system to pull emissions away from the combustion chamber. These emissions are then cooled and gradually reintroduced back into the combustion chamber. In addition to helping the environment, this recycling process also decreases fuel consumption and improves vehicle performance.
Consequences of EGR Valve Failure
Because the EGR valve is frequently exposed to considerable levels of carbon, dirt, and soot, it can easily become clogged in the open or shut position. This can cause several larger problems for your vehicle, perhaps the most problematic of which is increased emissions. In addition to being extremely harmful to the environment, increased emission rates can also cause your Volkswagen to fail an emissions test, which will make your vehicle illegal to drive until the situation has been resolved.
Another problem that may result from EGR valve failure is increased fuel consumption. By redirecting emissions back into the combustion chamber, the EGR valve offers the engine an additional energy source besides fuel, thereby decreasing fuel consumption. However, when the EGR valve becomes clogged, that additional energy source disappears, which means that the engine has to use up more fuel to travel the same distance. Unsurprisingly, the cost of this can really add up.
Often, an increase in fuel consumption caused by EGR valve failure is accompanied by decreased vehicle performance. The EGR system is interconnected with every other component of your Volkswagen’s engine; therefore, when it gets backed up, the effects resonate throughout the vehicle, causing reduced power and acceleration. Furthermore, a clogged EGR valve may also cause your vehicle’s engine to idle, especially if it is stuck in an open position. These problems might be little more than irritations in the short term, but if left unaddressed, they can cause serious, lasting damage to your vehicle.
Solving the Problem
As with all vehicular issues, preventing is the easiest way to keep problems from happening in the first place. Fortunately, the prevention process is often as simple as having the valve cleaned on a regular basis.
Experts recommend that you have a professional mechanic carbon clean your vehicle’s EGR valve after every 50,000 miles. A particularly good way to make sure that this is taken care of is by adding it to the list for your vehicle’s annual checkup, which you should be sure to make for a variety of reasons.
Of course, it’s impossible to anticipate or prevent all of the effects of wear and tear on a vehicle, and there’s a strong chance that your Volkswagen’s EGR valve will either clog or break entirely. If this happens, you should take your vehicle to a professional technician to have the problem solved as soon as possible.
The EGR valve is far too finicky of a component to be fixed at home, and attempting to do so will likely cause further damage to your vehicle. An experienced mechanic, however, will be able to repair or replace the valve efficiently and with comparatively little expense.
