A used genuine OEM Audi/Volkswagen coolant line, tube, or pipe, part number 5Q0121070BT, also replaces 5Q0121070BQ. This factory coolant line routes engine coolant through the 2.0L 1984cc 121ci turbocharged four-cylinder and the 2.0L MHEV (mild hybrid) engines. A cracked or leaking coolant line can cause overheating or a low coolant warning, so this replacement restores the original sealed flow path.
