What Causes Vibration When Braking at Speeds Above 100 mph?

Vibration when braking at speeds above 100 mph may be caused by issues with the brake pads or brake discs, or deformation and out-of-round conditions in the wheel hubs or tires. Brake Pad or Brake Disc Issues: For example, if either the brake pad or disc is uneven or deformed, it can lead to excessive runout of the brake disc. Additionally, impurities or oil contamination on the brake pads or discs can also cause this. The solution is to disassemble and inspect the brake pads or discs, replacing them if necessary. Wheel Hub or Tire Deformation and Out-of-Round Conditions: These can result in excessive dynamic imbalance, which can also cause vibration during braking. The solution is to perform a four-wheel dynamic balance check and inspect the tires and wheel hubs. If the deformation or out-of-round condition is too severe, replacement is required.

What does PQ mean in car safety inspection?

PQ in oil inspection refers to the amount of ferromagnetic particles in the oil, and the PQ value is also known as the mechanical wear index. The following is an introduction to PQ-related information: Instruments for measuring PQ value: There are specialized measuring instruments for measuring PQ value, called PQ meters, also known as ferrometers. Working principle of PQ: The working principle is that the tested oil sample is slowly and steadily transported by a double-tube infusion pump to the tray support above the magnet pole through the oil delivery pipe. The ferromagnetic wear particles in the oil are adsorbed on the center of the tray support surface under the action of a strong magnetic field. Meanwhile, the oil flowing through the strong magnetic field area is sucked back by the double-tube infusion pump along the oil return pipe, and then the inner wall of the oil delivery pipe and the center of the tray support surface are cleaned with a cleaning solution (such as tetrachloroethylene) that has strong dissolving power and good volatility.

How to Check Tire Pressure on Audi Q5?

Audi Q5 tire pressure checking method: Start the car, view the central display screen and touch the CAE button on the left; enter the relevant menu information in vehicle settings, select tire settings in the vehicle settings options; in tire settings, click tire monitoring to view tire pressure. There are three commonly used tire pressure monitoring methods: Direct tire pressure monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure tire pressure, and uses a wireless transmitter to send pressure information from inside the tire to the central receiver module, then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system will automatically alarm. Indirect tire pressure monitoring: When the pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, resulting in its rotation speed being faster than other wheels. By comparing the difference in rotation speed between tires, the purpose of monitoring tire pressure is achieved. The indirect tire alarm system actually relies on calculating the rolling radius of the tire to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the above two systems, equipping direct sensors in two diagonally opposite tires and a 4-wheel indirect system. Compared with using only a direct system, this composite system can reduce costs and overcome the defect that the indirect system cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires like the direct system.

How Long Does It Take for the ECU to Adapt After Replacing Spark Plugs?

How long it takes for the ECU to adapt after replacing spark plugs depends on the condition of the old spark plugs. If the old spark plugs are covered in carbon deposits and the electrodes are severely deformed, it may take three to four days for the ECU to adjust the program to optimal performance after installing new spark plugs. If the spark plugs are damaged, they can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty starting the engine, which affects normal vehicle operation. Severe erosion of the spark plugs, such as scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plugs are worn out and should be replaced. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the owner's manual. Typically, platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

How to Use the One-Touch Power Window Feature for All 4 Windows on the Boyue?

Inside the car, press and hold the air recirculation button on the air conditioning panel; outside the car, press and hold the lock or unlock button on the remote key. Introduction to the window control switch: The first button position works the same as a regular power window. The second position means that if you press and release the button, the window will automatically open or close completely. With regular power windows, you need to hold the switch until the window reaches the desired position, then release the button to stop the movement. Additional Information: The one-touch power window feature refers to a system where the car window glass can be controlled to move to the desired position with a single press of a button; it does not mean that all four windows move simultaneously with one button press, but rather that pressing the button once can raise or lower the window.

What are the certificate number and vehicle identification number respectively?

The certificate number is the identity number of the motor vehicle whole vehicle factory certificate, and the vehicle identification number is the vehicle identification code, which is the ID number of the car. Introduction to the certificate number: The vehicle certificate number is recorded in the first column on the upper right corner of the vehicle certificate, which is the motor vehicle whole vehicle factory certificate issued with the vehicle. When the owner registers a new car for license plates, the vehicle certificate needs to be submitted to the vehicle management office for retention. Therefore, after registration and license plate issuance, the owner receives the motor vehicle registration certificate instead of the vehicle certificate. The certificate is another important document for the car and is essential for vehicle registration. Only cars with a certificate meet the national requirements for motor vehicle equipment quality and related standards. The vehicle certificate is one of the mandatory legal documents required for motor vehicle registration, insurance, cancellation, and other procedures. Introduction to the vehicle identification number: The vehicle identification number (VIN), also known as the frame number, is the ID number of the car. Every motor vehicle has this identification number, commonly referred to as the 17-digit code. The certificate is another important document for the car and is essential for vehicle registration. Only cars with a certificate meet the national requirements for motor vehicle equipment quality and related standards.
