What Does the Used Car Business Include?

Used car business operations encompass the following aspects: 1. Traditional used car markets. This includes vehicle acquisition and sales, as well as proxy services for transfer of ownership, annual inspections, and insurance. 2. Used car brokerage firms. These act as intermediaries, typically offering used car consignment sales and used car sales on behalf of clients. 3. Used car auction companies. These conduct online auctions for used vehicles. 4. E-commerce. This refers to used car websites that provide information on used vehicles. Additional information: The business scope refers to the categories, varieties of goods, and service items that the state permits enterprises to produce and operate. It reflects the content of the enterprise's business activities and the direction of production and operation, serving as the legal boundary for the enterprise's business activities and embodying the core content of the enterprise's civil rights capacity and behavioral capacity.

Should the Generator Belt and Tensioner Pulley Be Replaced Together?

Both must be replaced together. The specific reasons are as follows: 1. The service life of the belt tensioner pulley is limited. 2. Cars generally exhibit the following scenarios: (1) The tensioner pulley may fail before the belt shows any signs of damage. Therefore, replacing the belt indicates that its lifespan has expired (2) Although the tensioner pulley may not be damaged at present, its remaining lifespan is short. While it is possible to wait until it fails to replace it, doing so carries significant risks. (3) If the tensioner pulley is severely damaged, it can damage the new belt, and even if it doesn't, it may not function properly. (4) Replacing the belt is to avoid breakage and driving failures, eliminating potential hazards. If the tensioner pulley is not replaced, the hazard remains. Therefore, for safety reasons, both the belt and the tensioner pulley should be replaced together.

What causes the jerk when shifting from CVTD to N?

Damaged solenoid valves are a major cause of jerking. The distinction is simple: occasional jerking occurs without a pattern, while consistent jerking happens at a certain RPM or when shifting between specific gears (e.g., from 2nd to 3rd). The reason for jerking at fixed speeds is: sludge in the transmission fluid circulating and clogging the oil passages in the valve body. Over time, this can lead to a series of transmission issues such as overheating, harsh shifting, and slipping. More reasons are as follows: 1. Presence of contaminants: Transmission jerking or harsh shifting is often not due to internal valve body damage but rather stubborn dirt and contaminants inside, especially when they accumulate in the valve body, blocking oil passages and preventing effective oil pressure regulation, leading to jerking, harsh shifting, and slipping. The traditional solution is to replace the transmission fluid. 2. Insufficient air intake: The engine's air intake system—engines require not only fuel but also air. If components like the air filter or throttle body are clogged or malfunctioning, reducing air intake, it can result in sluggish acceleration and jerking. The ignition system should not be overlooked either; if spark plugs misfire, leak, or fail to atomize properly, it can also affect engine acceleration.

What stickers are suitable for blue cars?

Generally, for blue cars, you can choose white or yellow stickers. White is the best option as it creates a harmonious and eye-catching effect, while yellow offers a contrasting look. Stickers primarily serve a decorative purpose, so it's important not to choose colors that clash too much with the car's original color. Here are some sticker considerations: 1. Avoid yellow and red stickers: Yellow and red are typically used for emergency repairs and warnings, so using these colors may result in penalties. It's worth noting that stickers cannot be applied arbitrarily—size and placement matter. Car stickers must comply with regulations; otherwise, they may fail annual inspections. If spotted by traffic police, you could also face fines. 2. Sticker area: If you want to apply stickers to your car, the total area must not exceed 30% of the car's surface. Exceeding this limit requires filing with the vehicle management office and obtaining a new vehicle license. Additionally, stickers must not be placed in any location that obstructs the driver's view or affects driving safety, as this will also cause the car to fail the annual inspection. Lastly, stickers resembling police insignia are prohibited.

Can the owner's phone number be queried through the license plate number?

Knowing the license plate number allows you to inquire about the owner's information by calling 114 or 122, but corresponding permissions are required. Below is an introduction to the types of license plates: 1. New energy vehicle special license plates: Green background with black characters and black borders. New energy vehicle license plates feature a gradient green color, while large new energy vehicle license plates have a yellow-green dual-color scheme. 2. Large vehicle license plates: Yellow background with black characters and black borders, applicable to medium (and above) passenger vehicles, cargo vehicles, special-purpose vehicles, semi-trailer tractors, and electric vehicles. 3. Trailer license plates: Yellow background with black characters and black borders. 4. Small vehicle license plates: Blue background with white characters and white borders. 5. Embassy and consulate vehicle license plates: Black background with white characters, red "Embassy" or "Consulate" characters, and white borders. 6. Hong Kong and Macau entry-exit vehicle license plates: Black background with white characters, white "Hong Kong" or "Macau" characters, and white borders.

What is the reason for BMW X3 air conditioning not cooling?

The reasons are: lack of refrigerant in the air conditioning system / the refrigerant pressure switch detects too low pressure or pressure switch failure; air conditioning compressor failure; air conditioning control unit failure; air conditioning function switch failure; air conditioning system wiring harness open circuit / short circuit failure. Here is the extended information: 1. How air conditioning works: The air conditioning system mainly works by the compressor compressing the gaseous refrigerant into a high-temperature and high-pressure gas, which then flows through the pipeline into the condenser. In the condenser, it is cooled and condensed into a high-pressure liquid refrigerant by the cooling fan. The high-pressure liquid refrigerant flows through the pipeline into the dryer reservoir, where it is dried and filtered before flowing into the expansion valve for throttling. Its state changes dramatically, turning into a low-temperature and low-pressure liquid refrigerant that enters the evaporator. In the evaporator, it absorbs the heat from the air flowing through the evaporator, lowering the air temperature and blowing out cold air, producing a cooling effect. 2. How refrigerant works: The refrigerant itself evaporates into a low-temperature and low-pressure gaseous refrigerant after absorbing heat, and is then sucked into the compressor through the pipeline for compression. As long as the compressor works continuously, the refrigerant circulates continuously in the air conditioning system, producing a cooling effect. When the compressor stops working, the refrigerant in the air conditioning system stops flowing, and no cooling effect is produced.
