Used OEM Audi AC Hose / Line / Pipe, part number 4M0816721BA, removed from a donor vehicle. This genuine air conditioning hose carries refrigerant between the compressor and condenser. Also known simply as an AC line, a failure typically results in a refrigerant leak, causing warm air from the vents. This part fits Audi Q7 and Q8 models with 2.0L turbo, 3.0L diesel, supercharged, mild-hybrid, or plug-in hybrid engines.
