A used OEM Audi/VW Coolant Reservoir Hose / Line, genuine part 5QF122109A. This hose (also known as a coolant line) carries coolant between the reservoir and the cooling system. When it cracks or leaks, you may notice low coolant levels, visible drips, or engine overheating. This piece interchanges with 3Q0122109A, 5QN122109A, and 5QN122109. It comes from a 2.0L Turbo 4-cylinder (EA888 gen) donor — common in the Audi Q3, VW Arteon, and Tiguan. A leaking coolant hose can leave you stranded; replacing it restores proper system pressure and flow.
