What are the consequences of leaving the parking ventilation on all the time?

Leaving the parking ventilation on all the time has little impact on the vehicle, as it does not activate the air conditioning compressor during operation, so it will not affect the vehicle. Here is some relevant information about parking ventilation: 1. Meaning: Parking ventilation refers to blowing natural outside air into the car without starting the compressor. On hot summer days when the car has been parked outside and the temperature inside is high, you can use your phone to activate the parking ventilation in advance to lower the interior temperature. 2. Working principle: Parking ventilation is a comfort feature of BMW. After the vehicle has been parked for a long time, when the owner enters the car, the vehicle will automatically activate the air circulation system or automatically turn on the air conditioning system to adjust the interior temperature. BMW refers to this as the parking ventilation device or parking ventilation system.
I've been driving for over a decade and often forget to turn off the parking ventilation system after parking. Once, I stopped by the roadside for lunch with the ventilation running for more than two hours, only to return and find the battery completely drained—the car wouldn't start at all. During the scorching summer heat, it's tempting to use it for cooling, but since it relies on the car battery, prolonged operation can lead to deep discharge and shorten the battery's lifespan. It might also consume extra fuel or electricity, and replacing the battery is quite expensive, costing several hundred yuan. Now I've learned my lesson: I use the car's built-in timer to set it for just 10 to 15 minutes, ensuring comfort without hassle. Most modern cars come with this timer feature, so I recommend checking your settings to avoid forgetfulness and reduce unnecessary energy waste. Also, make a habit of regularly checking the battery indicator light—it's crucial.
