This used OEM Coolant Reservoir Vent Tube / Line / Hose, genuine Audi part number 0P2121455G, also supersedes 0P2121455L and 0P2121455G. It came from a donor 4.0L 3996cc V8 mild-hybrid turbo (MHEV) engine found in Audi RS Q8 and SQ8 models. This hose connects the coolant reservoir to the vent system; a failing vent tube can cause coolant odor, visible drips, or a low-coolant warning light.
