A used OEM Audi Heater Coolant Hose / Line Set, part number 4G1819350BJ, includes the factory hoses that route coolant to the heater core. This set also replaces numbers 4G1819374G, 4G1819373AT, and 4G1819371AQ. Designed for 1.8L and 2.0L turbocharged four-cylinder engines, brittle factory hoses often develop cracks or swelling that lead to coolant loss and insufficient cabin heat. Using a genuine used set restores proper flow without aftermarket fitment guesswork.
