This Audi AC Hose / Line / Pipe (OEM 8W1816720) is a used genuine part removed from a donor vehicle. Also called an AC line or pipe, it carries refrigerant between the compressor, condenser, and evaporator. As these hoses age, common failure points include cracking or chafing that leaks refrigerant, leading to a warm cabin and reduced cooling performance. This example came from an Audi equipped with one of several engine options — including the 2.0L, 2.9L, and 3.0L turbo/supercharged units — found across the A4, A5, S4, S5, and RS5 model families.
