This is a used OEM Audi coolant hose adapter/connector, part number 8W0121089G, which also supersedes 8W0819334F. This genuine plastic fitting joins coolant hoses in the 2.0L turbocharged four-cylinder engines—including the TFSI and MHEV variants—found in A4, A5, and their Quattro and allroad models. When this adapter cracks or its O-ring seal fails, it can cause a visible coolant leak at the hose junction, leading to overheating.
