Mercedes EGR Valve Gasket - Reinz 6421410680

Product Information

An Exhaust Gas Recirculation (EGR) valve is a critical component in a vehicle’s emission control system. It recirculates a portion of the engine’s exhaust gases back into the intake manifold to be burned again. This process reduces nitrogen oxide (NOx) emissions by lowering the combustion temperature, helping the vehicle meet emissions regulations, and improving fuel efficiency.

• Rough Idle: A faulty EGR valve can cause a rough or unstable idle, as incorrect amounts of exhaust gases are recirculated into the intake manifold
• Check Engine Light: An issue with the EGR valve can trigger the check engine light. Common error codes for a failing EGR valve include P0400 to P0408, related to EGR flow or circuit issues
• Poor Fuel Economy: If the valve is stuck open, it can lead to excessive recirculation, reducing combustion efficiency and lowering fuel economy

About Reinz

Founded by Hugo Reinz in 1920, Reinz has been known for the manufacturing of Automotive gaskets for over 90 years. For almost a century Reinz has provided gaskets and sealing products for both auto manufacturers and as an aftermarket solution for car enthusiasts. Their full catalog features over 15,000 different products, providing a great selection for excellent value. Way back in 1962 Reinz became the (OEM) original equipment manufacturer for the prestigious Mercedes-Benz and Volkswagen car companies, a strong partnership that still continues to this day. The company continues to innovate and stay well ahead of the curve. For example, Reinz stopped using asbestos in their gaskets 12 years before it was banned in Germany in 1993. Reinz performs because every part they manufacture meets OEM standards – meaning you're getting great value that you can believe in. Many brands and models use sealing solutions from Reinz. In 1993 Reinx became a partner to the American company, Dana, to form the largest manufactures of components for automobile and commercial vehicles. The Gasket segment of Dana was Victor at the time ahich was then merged with Reinz to form the brand name of "Victor Reinz".
