Diesel Exhaust Fluid, also known as Adblue, is a liquid used to reduce the amount of air pollution created by a diesel engine. These diesel vehicles are equipped with a selective catalytic reaction system that reduces emission levels from diesel engine exhaust. The system automatically injects DEF into the exhaust system. To operate correctly, the Adblue tank of your EcoBlue diesel engine must be filled with Adblue fluid.
