This BMW coolant return hose, OEM 9292731, is a genuine used part removed from a donor vehicle. Also known as a coolant return line, it routes coolant back to the system after circulation. On the i3 and i3s — including both the 0.6L REX and EV/BEV variants — a failing hose can develop cracks or leaks, leading to overheating or low coolant warnings. Inspect for swelling or brittle sections.
