This Audi coolant/water pipe (078121071CF) is a used OEM rear-mounted tube for the 2.7L twin-turbo V6. Also known as a water pipe or tube, it routes coolant at the back of the engine. When this pipe cracks or its O-rings fail, you’ll likely spot a coolant leak near the firewall that can mimic a heater core failure. Genuine Audi replacement ensures correct fit and flow for the turbocharged V6 in A6 Quattro and Allroad Quattro models.
