This used OEM Heater Core Coolant Pipe / Tube (OEM part number 4M0819857) was removed from a donor Audi Q7. It is also known interchangeably as a coolant tube. Fitting 3.0L diesel, gas, and mild-hybrid engine variants from Audi, this pipe directs coolant to and from the heater core to supply heat to the cabin. When this tube fails or develops a leak, you may notice low cabin heat or visible coolant loss under the dashboard or near the firewall.
