A used genuine OEM Audi Coolant Reservoir / Tank / Bottle, part number 1S0121407E (also cross-referenced as Porsche 95810640710), is now available. This part supersedes 1S0121407C, 1S0121407G, and 5Q0121407J. It serves as the expansion tank for the cooling system, holding excess coolant as it heats up and expands. When this plastic reservoir develops cracks or a failing seal, it can leak coolant, leading to low fluid levels and potential engine overheating.
