After turning off the engine, the noise when opening the door mainly comes from the door hinges and limiters. Due to years of opening and closing, the door hinges and limiters experience wear and dust accumulation in the gaps, leading to vibration interference and abnormal noises during door operation. You can repeatedly apply engine oil with a cotton swab to the marked areas (red circles) of the door hinges and limiters, then repeatedly open and close the door. Repeat the steps of applying engine oil and operating the door until the noise disappears. The function of the door opening limiter is to restrict the degree to which the door can open. On one hand, it limits the maximum opening angle of the door to prevent it from opening too wide; on the other hand, it keeps the door open when needed, such as when the car is parked on a slope or during windy conditions, preventing the door from automatically closing.

Is Dual Clutch Manual or Automatic?

Dual clutch is automatic. Automatic transmissions include: traditional automatic transmissions, CVT transmissions, and dual clutch transmissions. Any transmission that does not require manual operation and completes gear shifting automatically is collectively referred to as an automatic transmission. Car transmissions can be divided into manual transmissions and automatic transmissions, with the latter further categorized into AT automatic transmissions, AMT semi-automatic transmissions, DTC dual clutch transmissions, and CVT continuously variable transmissions. Throughout the process from starting the car to normal driving, the driver can operate the clutch as needed to temporarily separate or gradually engage the engine and the drivetrain, thereby cutting off or transmitting the power output from the engine to the drivetrain. Its function is to allow the engine and the transmission to gradually engage, ensuring a smooth start; temporarily disconnect the engine from the transmission to facilitate gear shifting and reduce impact during shifting; and act as a separator during emergency braking to prevent overloading of the transmission and other drivetrain components, thus providing a certain level of protection.

Why can't I find my driver's license file number on 12123?

The reasons why the driver's license file number cannot be found on 12123: 1. It may be that the data from the traffic police department's system has not been updated to the 12123 software system. You need to wait for the system data to be synchronized before you can view it; 2. It may be that the correct issuance address of the driver's license was not selected during registration, which can cause some data to not be displayed or delayed; 3. It may be because the driver's license has expired and needs to be replaced with a new one. Solutions: 1. Check the duplicate of the driver's license, which has two numbers—the top one is the license number, and the bottom one is the file number; 2. You can go to the traffic police department or the vehicle management office consultation window and ask the staff to help you query; 3. You can also use the touch query terminal at the traffic police brigade to query using ID card recognition; 4. Search on the public security traffic police website by logging in with your name and ID number; 5. You can also use Alipay's city services to bind your driver's license, after which you can view it.
