The temperature gauge in your BMW is actually quite important. Unfortunately, most drivers don’t pay much attention to this gauge. On your dashboard you will generally have several needles that indicate speed, rpm’s, oil pressure, and the temperature of the engine.
The temperature gauge is there so that the driver, you, can keep an eye on operating temperature. If the temperature in the engine gets too high, it can cause catastrophic damage and complete engine failure. Engine overheating is one of the most common reasons why people end up stranded on the side of the road.
That is why it is important to make sure that the temperature gauge in your BMW is operating properly. Some people will assume that since the needle doesn’t move very much that it is working properly. However, if there is an issue with the sensor or any components between that sensor in the engine and the dashboard, it could lead to a failure of the temperature gauge to register the accurate temperature inside the engine.
Most cars will run with that temperature reading almost evenly between cold and hot, once the engine warms up to optimal performance levels. During the winter, it is going to take longer for the needle to move to that center position. That is one reason why it is best to warm up your car for several minutes or longer the colder it is outside.
If you notice that the temperature gauge is hovering below the “C” line or just slightly above it, it may indicate that there is a problem with the sensor or the gauge itself. It does not mean that your car is operating at a cooler temperature, thus more efficiently.
If you notice that the temperature gauge in your car is not moving to that center position, bring it to an authorized BMW service center to have a technician determine if there is a problem and, if so, the best way to fix it.
