A used OEM Audi AC Hose / Line / Pipe, part number 5WA816721N, is a genuine air conditioning line from a donor vehicle. This component carries refrigerant between the compressor and condenser, and a failure often results in a system leak that prevents the A/C from blowing cold. It fits the 2.0L turbocharged and 2.0L mild-hybrid (MHEV) engines found in the Audi A3, A3 Quattro, and S3.
