This EGR (Exhaust Gas Recirculation) valve is designed as a direct fit for various VAG (Volkswagen Auto Group) models, ensuring seamless integration with your vehicle's existing emissions system. Part number 04L131501S is manufactured to meet or exceed original equipment specifications, providing reliable performance and durability. The EGR system plays a crucial role in reducing nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gas back into the engine's combustion chambers. This process lowers combustion temperatures, which in turn significantly reduces the formation of NOx. Replacing a faulty EGR valve can resolve issues such as rough idling, poor acceleration, increased fuel consumption, and illuminated check engine lights. By restoring proper function, this valve helps maintain your vehicle's performance, fuel efficiency, and compliance with environmental regulations.
