This is a used OEM coolant hose assembly from a Volkswagen or Audi, part number 06K121051M (also replaces 06K121051J). This genuine VAG part is a coolant hose, line, and adapter for the engine cooling system. It serves EA888-gen 2.0L turbocharged and 1.8L TSI/TFSI engines, plus the 2.0L TDI diesel and 2.0L MHEV mild-hybrid variants. A failing coolant hose typically causes visible leaks, low coolant levels, or engine overheating.
