Factors that Lead to the Glowing of the Low Coolant Light in BMW

While BMWs are well-known worldwide for their stamina, endurance, and exceptional quality of engineering and design, they still encounter issues like every other mechanically-engineered item. Caring for your BMW is the best way to combat problems from affecting your vehicle’s performance and reliability. However, when something does come up, it’s critical that we pay attention to the warning signs our car is trying to communicate to us.

Being aware of the ways our car attempts to alert us of issues is nearly as important as following through with ongoing maintenance. Noticing the lights that illuminate in the dashboard is the most common way that problems are communicated to the driver—and to automotive professionals for that matter. For instance, when your BMW’s dash displays the “low coolant” light, it emits a code that lets the diagnosing professional know what avenue to take for treatment. In this article, you’ll discover some of the potential issues that could contribute to the low coolant light coming on, and what you can do to prevent these issues.

BMW Low Coolant Light

What Factors Might Cause the Coolant Light to Come on?

You might be surprised to learn that a “low coolant” light doesn’t necessarily mean that coolant is low; but there could be other issues, including failing parts leading to coolant becoming low over time. Since most modern vehicles, including most BMWs, utilize coolant that’s developed to last a significant amount of time, the low coolant light is concerning.

Low Coolant

Of course, it is highly possible that the illuminated light is indeed correct and that your coolant level is not where it should be. Low coolant is a problem for your car’s cooling system, especially in a performance vehicle like a BMW that requires higher quality conditions to run optimally.

Faulty Sensors

BMWs are basically a complex network of communicating technology. The car’s warning system runs off of a series of sensors for various parts and functions of your vehicle. There are sensors that are specifically purposed to determine the coolant level and the functioning of the cooling system. These sensors can also fail on their own, communicating to the driver that there’s a problem when indeed there isn’t.

Failing Radiator Seal

The radiator circulates the coolant. In order to do this, it must contain the coolant but it also must contain the pressure in the system. It does so by way of airtight seals, which can become damaged or corroded. When the cooling system reaches a low pressure, the car might perceive this as low coolant. In this case, the sensor will likely need to be replaced.

Coolant Leak

Coolant leaks can occur due to a number of reasons, including a broken radiator seal or a compromised radiator. It’s important to have your coolant levels inspected and keep an eye out for leaks beneath your car or throughout your engine to detect leaks in a timely manner—otherwise you might wind up on the side of the road with an overheated engine.

What You Can Do To Prevent Coolant Issues in Your BMW

Many drivers abstain from engaging in ongoing car maintenance because it can be expensive; however, it’s often surprising to learn that automotive maintenance is not nearly as costly as the repairs that can result from lack of maintenance. By maintaining your BMW’s overall health, including inspecting and servicing the cooling system, you can prevent coolant leaks, radiator seal issues, and other problems that could lead to problems with low or inadequate coolant.
