A used OEM Audi coolant pipe / tube / line, part number 4G0121071N, removed from a donor vehicle. Also called a coolant tube or line, this component routes coolant between the engine and cooling system. It fits Audi A6 and A7 Quattro models equipped with the 2.8L V6, 3.0L TDI diesel, and 3.0L supercharged gasoline engines. A cracked or leaking pipe can cause coolant loss and overheating; this used part restores proper circulation without the cost of new.
