The engine jolts, has large power losses and smokes heavily from the exhaust under full load? In addition the engine warning light lights up? Then there is probably a defect in the exhaust gas recirculation valve! This causes excessive emissions of pollutants. As a result, the car does not pass the exhaust emission test and therefore does not receive a TÜV sticker.
For this reason, it is important that the EGR valve is regularly tested and that the quality of the spare part is important. You are on the safe side with original parts from the manufacturer. Here you have not only the guarantee for highest quality, but also on absolute fitting accuracy. At the bottom of the page you will find a brief outline of how the valves work and a few tips on how to use and maintain them.
What is the EGR valve needed for in the car and how does the principle of exhaust gas recirculation work?The EGR valve is the abbreviation for the exhaust gas recirculation valve and is a component of the exhaust system. The valve is also synonymously referred to as the EGR valve. The task of the valve is to reduce the combustion temperature of the exhaust gases. This is done by returning some of the exhaust gases to the combustion process via the cylinder. Hence the term exhaust gas recirculation.
Modern diesel vehicles also have a AGR cooler, which further reduces the temperature of the exhaust gases before recirculation. The exhaust gas recirculation process reduces the emission of nitrogen oxides to the environment by up to 50 percent, thus making a significant contribution to environmental protection. The principle is thus one of the most important methods of reducing pollutants.
Leading vehicle manufacturers recommend regular inspection of the EGR valve and have therefore included inspection of the EGR valve at the usual inspection dates. This guarantees a long service life and avoids expensive follow-up costs due to repairs of the swirl flaps or the turbocharger. In addition, it prevents the soot particle filter from clogging in diesel vehicles.
A special care of the exhaust gas recirculation valve is not necessary, but there are a few tips that should be followed.
High quality EGR valves should be resistant to high temperatures, exhaust gases and corrosion. So that you can have the next exhaust gas test carried out with peace of mind, rely on the original spare parts of the vehicle manufacturer for the EGR valve. We have listed the appropriate original EGR valves for all common vehicle types in our range. In addition, our service team will be happy to help you choose the right exhaust gas recirculation valve and answer any questions you may have about the product.
