The Audi coolant hose (OEM 3Q0121107A) is a used genuine part, originally fitted to an A3 Sportback e-tron with the 1.4L PHEV turbo engine. This water hose carries coolant between engine components; a cracked or leaking hose can cause overheating or low coolant warnings. Also known as a coolant/water hose, it is a direct replacement for the original equipment part.
