This used OEM Audi heater coolant hose, OEM part number 4E1819374, was removed from a donor vehicle. Also known as a heater coolant line, it circulates engine coolant to the cabin heater core. A cracked or leaking hose can cause coolant loss, overheating, or insufficient cabin heat. This original hose was fitted to both naturally aspirated V8, V10, and W12 engines in the A8 and S8.
