This used genuine OEM AC hose (line/pipe), part number 5Q0816721AG, was pulled from a donor Audi or Volkswagen. It also replaces 5Q0816721M, 5Q0820721K, 5Q0816721C, and 5Q0816721Q. This component routes refrigerant between the compressor, condenser, and evaporator. Common failure is a refrigerant leak from the hose or its O-rings, causing weak or no cabin cooling. It is compatible with 1.4L, 1.8L, and 2.0L turbocharged, diesel, and hybrid engines in select A3, TT, Golf, and Arteon models.
