A used OEM Audi AC Refrigerant Line / Pipe Assembly, part number 4M8816886, is a rear-mounted refrigerant line for the air conditioning system. This genuine Audi part carries no interchange numbers. It comes from a donor vehicle and serves the 3.0L and 4.0L MHEV V6 and V8 engines in the Q7, Q8, RS Q8, and SQ8. When this refrigerant line leaks or fails, the AC system loses cooling capacity and may blow warm air.
