This is a used OEM Audi/VW coolant reservoir, OEM part number 5Q0121407G, also replacing 5Q0121407A and 5QM121407B. Also called the coolant tank or bottle, this plastic reservoir holds the engine's coolant and provides a fill point for the cooling system. A cracked or leaking tank is a common failure, often causing low-coolant warnings or visible drips under the hood.
