This used genuine OEM Heater Coolant Hose / Line Set (part number 4M0819350F, also listed as Porsche PAB81935040) was removed from a donor vehicle. It carries hot coolant from the engine to the heater core, supplying cabin heat. Cracks or leaks in this hose set can result in coolant loss, poor heater performance, or overheating. Fits multiple Audi Q7, Q8, RS Q8, and Porsche Cayenne configurations with 2.0L, 2.9L, and 3.0L gasoline, diesel, MHEV, and PHEV engines (EA839 and related families). A common failure point on these models, this used OEM hose set is a direct replacement.
