A used genuine OEM Volkswagen / Audi heater core, OEM part number 1J1819031A, also replaces 1J1819031 and 1J1819031B. This is the cabin heater core, a small radiator-like component that circulates hot engine coolant to provide warmth to the vehicle's interior through the HVAC system. When a heater core fails, common symptoms include a lack of heat from the vents, a sweet coolant smell inside the cabin, or fogging on the windows.
