It is not normal for a car display screen to get hot. This could indicate an issue with the internal lamp tubes, and it is recommended to visit a repair shop or a 4S dealership for inspection and repair. Below are some relevant details: 1. Screen: The circuit board is located very close to the back of the LCD screen. During operation, the temperature of the circuit board rises, and the heat transfers to the screen, causing it to become very hot. 2. Backlight: Some LCD screens use CCFL tubes as backlight sources. These tubes generate significant heat during operation. Since the entire LCD screen (including the backlight system) is sealed, most of the heat is dissipated through the surface of the screen, making it warm. It is normal for an LCD screen that has been running for a long time to feel slightly warm, and this does not pose any harm to the screen itself, so there is no need to worry.

If an inspection reveals that the coolant level is actually adequate, it may be a false alarm. In this case, you can try restarting the vehicle to see if the warning disappears. If it does, no repair is needed. BMW offers various models, including the i, X, and Z series.

Is it normal for the production dates of car window glass to be different?

It is normal for the production dates of car window glass to be different, as car glass factories produce on assembly lines, and different batches of glass will naturally have different production dates. Car glass usually bears letters, numbers, and patterns representing the car manufacturer, glass brand, production date, and the China 3C compulsory certification mark. The manufacturing process of car glass involves heating the glass in a furnace to near its softening temperature, then quickly transferring it to air grids with varying cooling intensities for uneven cooling. This creates different stress levels between the main viewing area and the peripheral areas of the glass. Typically, glass produced this way is zone-tempered glass.
