Audi Heater Coolant Supply Hose / Line OEM 4E1819672A, a used genuine part removed from a donor vehicle. This hose delivers engine coolant to the heater core on Audi A8 Quattro models equipped with the 4.2L V8 (both 4163cc and 4172cc variants). Over time, the rubber can develop cracks or the fitting may weaken, leading to coolant leaks that reduce cabin heat or risk engine overheating.
