The BMW low coolant warning light is a dashboard indicator that tells the driver when the engine coolant level is low. The light comes on when the coolant level drops below a certain point, typically about 15% of the total capacity. The purpose of the BMW low coolant warning light is to prevent engine damage caused by overheating.
When the coolant level gets too low, it can no longer effectively remove heat from the engine, leading to engine damage. If you see the BMW low coolant warning light come on, add coolant to the machine as soon as possible. In most cases, you can add coolant to the overflow tank. However, if the coolant level is very low, you may need to add it directly to the radiator.
