This 10-liter container of VAG Urea Solution AdBlue is specifically formulated to meet the stringent requirements of modern diesel engines equipped with Selective Catalytic Reduction (SCR) technology. AdBlue is a diesel exhaust fluid (DEF) that works by reducing harmful nitrogen oxide (NOx) emissions. When injected into the exhaust stream, AdBlue reacts with NOx in the presence of a catalyst, converting it into harmless nitrogen and water vapor. This process is crucial for meeting current and future emissions regulations. Using genuine VAG AdBlue ensures compatibility and optimal performance of your vehicle's SCR system. It prevents potential damage to the catalyst and AdBlue injection system that can occur with non-approved fluids. This 10L pack is a convenient size for regular top-ups. Always store AdBlue in its original container, away from direct sunlight and extreme temperatures. Ensure you handle it with care to avoid spills. Refer to your vehicle's owner's manual for specific AdBlue refill instructions and recommended intervals.
