Not only for BMW models, but for any fuel-powered vehicle, the normal water temperature should be 90 degrees. Introduction to the Automotive Water Temperature Sensor: The interior of the automotive water temperature sensor contains the water temperature sensor itself. The lower the temperature, the higher the resistance; conversely, the resistance decreases. It is installed in the water jacket of the engine block or cylinder head, in direct contact with the coolant, thereby measuring the temperature of the engine coolant. Principle of the Automotive Water Temperature Sensor: The electronic control unit measures the temperature of the engine coolant based on this change—the lower the temperature, the higher the resistance, and vice versa. The electronic control unit uses this variation to determine the engine coolant temperature, serving as a correction signal for fuel injection and ignition timing.

How Long Can a 2008 Car Be Driven?

A 2008 car can be driven as long as it meets the following conditions: first, it must pass the annual inspection; second, there are no local driving restrictions in place; third, the mileage does not exceed 600,000 kilometers. Here are the relevant details: 1. Whether a car is scrapped is not determined by its age but by its mileage. A car must be forcibly scrapped once it reaches 600,000 kilometers. For specifics, refer to Articles 5 and 7 of the "Regulations on the Compulsory Scrapping Standards for Motor Vehicles." 2. Regarding driving restrictions, for example, a 2008 car typically meets the National III emission standard. If a local policy prohibits vehicles with National III emissions from being driven on the road, then the car cannot be used. Major cities like Beijing, Shanghai, Guangzhou, and Shenzhen have already implemented corresponding driving restrictions. 3. Additionally, cars older than 15 years must undergo inspections every six months, meaning two annual inspections per year. If the car fails even one inspection, it cannot be driven. For specifics, refer to Article 16 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China."

What to Do When the Car is Too Close to the Left Side?

Straighten back a little, then drive forward to the right a bit, and straighten back again. Repeating this two or three times should do the trick. Depending on the size of the space, if you realize it's not suitable right after entering, you can try reversing out the same way and then re-entering. If the car isn't too close, you can make slight adjustments. If it's extremely close, you'll need to be very careful and move out bit by bit.
