This used OEM Audi alternator coolant adapter pipe, part number 079121131AH, was removed from an RS4. Also called the alternator coolant line, this genuine pipe routes coolant to and from the alternator to prevent overheating. A common failure symptom is a coolant leak at the connection, which can lead to alternator or charging system issues if left unchecked. This fits both 4.2L V8 engine variants (4163CC and 4172CC).
