If you notice a coolant leak in your BMW F30, it's important to address it promptly. A coolant leak can cause low coolant levels, leading to engine overheating. The most frequent cause of a coolant leak is a hose issue, where hoses connecting to the radiator and engine may come loose. It's also possible for a rubber hose to dry out and crack, causing a leak in the engine bay. If these issues are not the culprit, check the radiator for signs of damage or cracks.
