A used OEM Diesel Exhaust Fluid Tank / DEF Reservoir, part number 4G0131879C, is available from a donor vehicle. This part also replaces earlier versions 4G0131879A, 4G0131879B, and 4G0131879. It stores the urea solution injected into the exhaust to reduce NOx emissions; when the tank or its level sensor fails, the system may trigger a warning or limit engine performance.
