Audi A6 and A7 heater coolant hose/line, OEM part number 4G1819350AH, also replaces 4G1819371AC. This used genuine hose carries engine coolant to the cabin heater core, common on 2.8L and 3.0L V6 gas (including supercharged) and 3.0L V6 diesel applications. When the hose cracks or its o-ring fails, you may notice coolant loss, a sweet smell, or poor cabin heat.
