The Audi lower radiator coolant hose / line, OEM part number 8R0121049B (also replaces 8R0121055D), is a used genuine component removed from a donor Q5. This coolant hose routes fluid between the radiator and engine block on 2.0L turbocharged engines (including TFSI and hybrid variants). When this line cracks or leaks, you'll typically see coolant puddles under the vehicle or notice the low-coolant warning light.
