What is the BMW air conditioning auto function?

BMW air conditioning auto is the automatic mode of the air conditioning. When pressed, the air conditioning will operate in automatic mode, automatically adjusting the airflow and the compressor's engagement based on the set temperature and the actual ambient temperature. If the car makes a vibrating sound as soon as the air conditioning is turned on, it may be due to the following reasons: 1. Dirty air filter: A dirty air filter can cause excessive noise and abnormal sounds. 2. Debris in the blower fan blades: Debris in the blower fan blades can cause abnormal sounds. You can test this by turning on the blower without starting the engine to see if the sound appears. If it does, the issue is likely with the blower. 3. Fan issues: Deformed fan blades or a damaged fan motor in the car's air conditioning system. 4. Worn clutch bearing: A worn clutch bearing in the air conditioning pump can cause the engine sound to become louder when the air conditioning is turned on. This component cannot be replaced individually; the entire air conditioning pump assembly must be replaced.

Where is the PCV valve located on the Baojun 730?

The PCV valve of the Baojun 730 is located inside the crankcase. Here are the specific details: 1. Function of the PCV valve: At the end of the engine's combustion process, some unburned mixture leaks into the crankcase from the piston rings under high pressure. These blow-by gases can escape into the atmosphere, causing pollution. If these gases are not removed, they can dilute the engine oil in the crankcase, leading to oil degradation and premature wear of engine components. Therefore, a PCV valve is installed on the valve cover to allow these exhaust gases to re-enter the engine through the intake manifold for re-combustion. 2. Working principle of the PCV valve: The PCV valve is controlled by vacuum. When the engine is idling, the intake manifold has vacuum, which causes the plunger to be directly sucked against the spring force, preventing the exhaust gases from flowing. At high speeds, the spring force holds the plunger in place, also preventing the exhaust gases from flowing. At medium speeds, the vacuum suction from the engine's intake manifold overcomes half of the spring force, causing the plunger to wobble within the valve body, allowing the exhaust gases to start flowing into the intake manifold.

Can You Turn in 5th Gear?

It is possible to turn in 5th gear, but it is quite dangerous and not recommended. When a car needs to make a turn, you should decelerate and downshift to 2nd gear in advance. Applying light throttle while entering the turn with the gear engaged helps reduce vehicle roll. During a turn, you need to operate the transmission gear lever to select the appropriate gear based on the engine power and the speed while turning. Here are some safe methods for turning: 1. The speed should not be too fast when turning. Reduce speed before entering the turn and go through the turn slowly. Avoid using emergency brakes and meeting other vehicles in the curve whenever possible. 2. When turning, the steering wheel operation should coordinate with the speed. Turn and return the wheel as needed, and adjust the turning angle according to the actual situation. Otherwise, it is easy to lose control and cause an accident, and it also makes it difficult for the driver to observe oncoming vehicles in the curve. 3. When turning, always check the rearview mirror to ensure there are no vehicles or pedestrians behind or to the side before making the turn, to avoid collisions caused by forced turns.

What is the reason why the 3008 parking brake failure cannot start?

3008 parking brake failure cannot start because there is a fault in the parking brake system. It may be caused by a problem with the brake light switch, resulting in the ECU not receiving the normal start power signal. It is recommended to contact a professional technician at a 4S shop to use a computer to check the specific fault content and then carry out targeted repairs. The following are methods to reduce car failures: 1. Engine oil change knowledge: The engine oil change cycle is 5,000 kilometers. Not all models are suitable for car owners to change the oil themselves. You can learn to check the oil dipstick to determine whether the oil needs to be changed. When changing the oil, the oil filter must also be replaced. 2. Antifreeze usage knowledge: Antifreeze is best used all year round. In addition to its antifreeze and cooling functions, antifreeze also has cleaning, rust removal, and anti-corrosion effects, reducing corrosion of the radiator and protecting the engine. Pay attention to choosing the correct color of antifreeze and do not mix different types. 3. Brake fluid usage: The function of the brake system is closely related to the brake fluid. When inspecting or replacing brake pads, brake discs, and other hardware, do not forget to check whether the brake fluid needs to be added or replaced. 4. Transmission oil: To ensure flexible steering of the car, frequently check the transmission oil. Whether it is gear oil or automatic transmission fluid, pay attention to the oil model.

Is It Serious to Mix a Little Bit of Coolant?

It is not recommended to mix coolants. However, if only a small amount is mixed, it will not affect the vehicle. The mixed coolant must be of the same brand. Different brands of coolants may have varying production formulas, and if mixed, chemical reactions between various additives are likely to occur, rendering the additives ineffective. Method for Replacing Coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connections to different parts, and the coolant flows through it before being distributed to various sections of the car to function. If there is any leakage of coolant in this part, replace the hose or resecure the connection as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continue adding water to ensure it flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially draining from the reservoir may appear slightly pinkish; continue adding clean water until clear water flows out. Remember to remove the heater hose and drain the water from the heater core. About an hour after draining, add the new coolant through the radiator hose—this allows the coolant to flow quickly into the radiator. Then, add another bottle of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Top up the coolant to the "MAXT" mark on the reservoir.

Where is the air filter located in a 2017 Lavida?

The air filter of the Volkswagen 2017 Lavida is located on the upper left side of the engine compartment. According to the Lavida maintenance manual, the air filter should be replaced every 1-2 kilometers or during each maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The function of the air filter: to filter out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinders and preventing airborne dust from being sucked into the engine, which accelerates the wear of the piston group and cylinders. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or air element. It is mainly used in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filtration device. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinders, accelerating the wear of the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand from the air, ensuring that a sufficient amount of clean air enters the cylinders. A dirty air filter: Using a dirty air filter while driving will result in insufficient engine air intake, leading to incomplete fuel combustion, unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car air filter is a device that removes particulate impurities from the air, consisting of one or several components that clean the air. Its main function is to filter out harmful impurities from the air before it enters the cylinders, thereby reducing early wear of the cylinders, pistons, piston rings, valves, and valve seats. Therefore, before air enters the cylinders, it must pass through the fine filtration of the air filter. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if you find little dust and minor blockage, you can use high-pressure air to blow it clean from the inside out and continue using it. A severely dirty air filter should be replaced promptly.
