What is the fault of BMW x3 start-stop function?

The failure of BMW x3 start-stop function may be caused by low water temperature and low battery voltage, and the specific reasons are as follows:

It is not a fault, but the working environment does not meet the requirements of automatic start-stop. It is required that the engine temperature and water temperature reach the ideal state, the passengers in the car fasten their seat belts and the doors are locked. Turn on the warm air key, it will not start or stop automatically.

Water temperature, battery:

Many factors, such as low water temperature, low battery voltage and running state of air-conditioning compressor, will affect the normal operation of automatic start-stop system.

Reason for being in startup state:

If the car has just started, its automatic start function will not start, and it will only start when the water temperature of the car reaches the ideal state.

Weather reason:

It may be that the weather is too cold, the engine speed is relatively high, and the water temperature can't get up, so the engine can't start and stop, or the throttle valve is dirty or out of order.
