This is a genuine VAG (Volkswagen Auto Group) replacement reduction agent tank, part number 5Q0131877S. Designed to meet the exact specifications of your vehicle, this tank is crucial for the proper functioning of your AdBlue (Diesel Exhaust Fluid) system. The reduction agent tank stores the AdBlue fluid that is injected into the exhaust stream to reduce harmful nitrogen oxide (NOx) emissions. A properly functioning tank ensures a consistent supply of AdBlue, which is essential for meeting modern emissions standards and keeping your vehicle running cleanly. If your current reduction agent tank is damaged, leaking, or malfunctioning, replacing it with this genuine VAG part will restore the integrity of your emissions control system. This ensures your vehicle continues to operate efficiently and in compliance with environmental regulations.
