This used OEM Audi coolant reservoir hose / line (part 8R0121081AQ) was removed from a donor Q5. It serves as the coolant passage between the expansion tank and engine, and over time the rubber can develop cracks or leaks, leading to coolant loss and potential overheating. This specific line fits 2.0L turbocharged (gas, flex-fuel, hybrid) and 3.0L diesel drivetrains across multiple Q5 model years.
