This used OEM coolant hose / line, genuine Audi part 9J1121178B, was removed from a donor vehicle. Also referred to as a coolant line, this rear-mounted hose circulates coolant within the battery thermal management system of battery-electric models. A failing hose often leaks coolant, leading to reduced cooling performance and potential thermal derating. Installation requires a qualified technician for proper clamping and bleeding.
