Audi Coolant Reservoir Vent Hose, OEM part number 8W1122051, is a genuine used part from a donor vehicle. This hose connects the coolant reservoir to the vent system, allowing air to escape and preventing pressure buildup in the cooling circuit. When this vent hose fails or becomes blocked, you may notice coolant leaks, air pockets in the system, or overheating—especially after a service where the reservoir was drained. It serves the EA839 2.9T and 3.0T engines, as well as the 2.0L TFSI and MHEV variants.
