Thumbnail Filmstrip of Audi/VW Genuine Urea, Diesel Exhaust Fluid (DEF) - GUS052910A3 Images
Function: It is a high-purity urea solution used in modern Audi and VW TDI (diesel) engines equipped with Selective Catalytic Reduction (SCR) systems. It breaks down harmful nitrogen oxide (NOx) emissions into harmless nitrogen and water vapor.
Volume/Quantity: 2.5 Gallons (9.46 Liters).
Common Applications: Widely used in TDI models equipped with diesel emissions fluid reservoirs, such as the Audi Q7 TDI, Volkswagen Touareg TDI, and Passat TDI.
Modern diesel vehicles require this fluid to operate legally and efficiently; if the AdBlue/DEF reservoir runs completely empty, the vehicle's engine will eventually prevent itself from restarting until it is refilled.
