BMW warning: Engine overheating, drive with caution. You should not continue driving. The reasons for engine overheating are as follows: Insufficient coolant: Prolonged water circulation during engine operation can cause the coolant in the engine cooling system to gradually deplete, leading to a lack of water in the radiator. If the owner does not promptly inspect, detect, and replenish the coolant, this can easily result in engine overheating. Cooling fan malfunction: A damaged cooling fan or a short circuit in the wiring can cause the fan to stop working or operate at a slow speed, preventing the engine's heat from dissipating and naturally causing the engine temperature to rise.

When I see the BMW pop-up warning 'Engine Overheated, Drive with Caution,' my heart instantly tightens. This is no minor issue—continuing to drive poses significant risks, potentially causing severe internal engine damage like cylinder explosion or gasket meltdown, with repairs easily costing tens of thousands. I’ve experienced a similar situation before when unnoticed coolant leakage led to engine shutdown after just a short drive. My advice: immediately pull over safely, shut off the engine, and let it cool for at least 30 minutes while checking coolant levels—top up with distilled water if critically low, but avoid pushing the car further. Always call roadside assistance for a tow to a professional shop for a full cooling system inspection. Regular maintenance, including periodic coolant replacement and radiator flushing, can prevent such incidents.

Honestly, I'd risk driving short distances when the engine overheats, but only as a last resort. For example, if it's hard to stop on the highway, I'd drive slowly to the nearest service area, turn off the AC to reduce engine load, and open windows for ventilation. But this is just a temporary solution—hidden dangers remain. Overheating accelerates engine component wear and even risks fire. Root causes could be fan failure, water pump damage, or coolant blockage. I recommend using an OBD scanner to check trouble codes and a quick DIY coolant inspection (shouldn't be cloudy). Check for leaks after stopping. In most cases, don't gamble—calling a tow truck is safer and cheaper. BMW parts are expensive; don't risk ruining the entire engine to save trouble.

When the engine overheating warning appears, my first thought is a cooling system issue, like a clogged radiator or a failed cooling fan. Continuing to drive is absolutely not advisable, as thermal expansion could cause the engine to seize or even blow a gasket. Once, I ignored the warning and kept driving, only to break down halfway and end up paying hundreds in towing fees. The correct approach is to immediately pull over safely, turn off the engine, and let it cool naturally for at least half an hour without moving the car. Check the coolant reservoir; if the level is low, don’t top it up yourself—consult a professional. BMW’s electronic control systems are sensitive, and the 'Drive Moderately' message might be a buffer period, but it doesn’t mean you can drive long distances. In emergencies, drive short distances with the AC off, but get it repaired as soon as possible to avoid repeated failures.
