Can You Still Drive When the BMW 3 Series Coolant Warning Light Comes On?

[LeAiden]

When the coolant warning light comes on in a BMW 3 Series, you should not continue driving. Continuing to drive may cause the engine temperature to rise excessively, leading to engine damage. To avoid unnecessary losses and ensure safety, it is not advisable to keep driving. Below are the reasons for the coolant warning light: Overheating: If the warning is due to the engine overheating, it is best to pull over, keep the engine idling, open the hood to allow it to cool down until the temperature warning disappears. Low Coolant Level: If the warning is caused by insufficient coolant and you don’t have coolant on hand for immediate refill, you can add an appropriate amount of purified water, preferably soft water (such as distilled water). Do not use tap water or other hard water, and avoid adding too much, as this can alter the coolant’s boiling point.
