A used genuine OEM Audi Coolant / Water Hose, part number 4M0121449BG, is available from a donor vehicle. This rear right hose is a factory coolant line for the 3.0L diesel, gas, and mild-hybrid V6 engines in the Audi Q7. The hose carries engine coolant to the rear of the engine bay; a failure can cause a visible coolant leak, steam, or an overheating condition and a low-coolant warning.
