This genuine OEM heater coolant hose / line, number 4H1819344B, was removed from a donor Audi A8 Quattro. As the factory coolant line that feeds the heater core, it circulates hot coolant to provide cabin heat. On the 3.0L supercharged V6, this hose can develop cracks or soft spots over time, leading to coolant leaks, low heat output, or overheating.
