For the Audi A6, A6 Quattro, and A7 Quattro, this used OEM coolant reservoir hose line (part 4G0122109AF, also replaces 4G0122109) carries coolant between reservoir and engine. It fits multiple 3.0L V6 supercharged and 2.8L V6 engines, as well as the 3.0L diesel. Over time, this hose can develop cracks or leaks, leading to coolant loss and potential overheating. A leaking hose is a common failure that should be addressed promptly to avoid engine damage.
