According to the vehicle's maintenance manual, the air filter of Audi Q3 should be replaced every 40,000 kilometers or during every other maintenance service. This helps reduce the accumulation of sludge in the throttle body. The location of the car's air filter varies depending on the intake form and engine structure, but it is generally located in the air filter housing on the engine intake pipe. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. The function of the car's air filter is to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinders and preventing airborne dust from being sucked into the engine, which could accelerate wear on 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, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust in the air will be drawn into the cylinders, accelerating wear on the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially 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 particles, ensuring sufficient and clean air enters the cylinders. Using a dirty air filter while driving can lead to insufficient engine air intake, incomplete fuel combustion, unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car's air filter is a device that removes particulate impurities from the air, consisting of one or several filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinders, reducing early wear on the cylinders, pistons, piston rings, valves, and valve seats. Thus, air must pass through the fine filtration of the air filter before entering the cylinders. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if it is lightly clogged with minimal dust, it can be cleaned by blowing compressed air from the inside out and reused. Severely dirty air filters should be replaced promptly.

Can a tire with exposed cords still be used?

Tires with exposed cords inside should not continue to be used. Below are specific details about when to replace car tires: 1. Replacement timing depends on conditions: For drivers with good driving habits, tires generally need replacement every 3-5 years or after traveling 60,000-80,000 kilometers. If driving conditions are harsh, such as frequent travel on gravel roads or in heavy traffic with sudden braking and sharp turns, the replacement interval will be shorter. 2. Tire aging period: The main material of tires is rubber, which naturally ages over time. Signs of aging include hardening of the rubber and small cracks appearing on the tire sidewalls. The natural aging period is typically 4-5 years. Tires should be replaced after 5 years of use to prevent the risk of blowouts. 3. Observe tire wear: If tire wear is severe, and the tread pattern is level with the wear indicators, the tires should be replaced. Otherwise, braking on wet roads will be more difficult, and the vehicle may easily lose control. Driving on very rough roads with worn tires also increases the risk of blowouts.

How many times can I retake the Subject 1 exam if I fail?

There is no limit to the number of times you can take the Subject 1 exam. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," you can take the Subject 1 exam twice on the same day. If you fail the first attempt, you can retake it for free a second time. If you fail the second attempt as well, the Subject 1 exam for that day will be terminated, and you can only schedule another exam after ten days. Subject 1, also known as the theoretical driving test or driver's theory exam, is part of the motor vehicle driving license assessment. The exam content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is conducted on a computer and has a time limit of 45 minutes. To pass the Subject 1 driving test, you need a score of 90 or above. The test consists of 100 questions, including single-choice and true/false questions, with each question worth 1 point, totaling 100 points. If you answer 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1 exam content: Driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 exam precautions: During the exam, candidates should dress appropriately—no slippers are allowed. Electronic devices and bags are prohibited in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen, and store personal belongings in lockers before entering the exam room. Upon entering the exam room, you will be assigned a seat at the identity verification counter. Once seated, begin the exam. Ensure the camera is aligned with you and follow exam discipline. If you fail the first attempt, you can retake it on the same day. If you fail again, you must pay to reschedule. After the exam, queue to collect your score report and sign it. An unsigned score report is considered invalid. There is no limit to the number of times you can schedule the Subject 1 exam. Each subject can be taken once, with one retake allowed if you fail. If you do not attend the retake or fail it again, the exam for that subject will be terminated, and you must reschedule. In contrast, Subject 2 and Subject 3 only allow five exam attempts. Subject 2 and Subject 3 exams can be rescheduled after ten days. If you fail the Subject 3 safe driving knowledge test, your previously passed road driving skills test results remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge exam. Subject 2 refers to the field driving skills exam. Subject 3 consists of two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject 4."

Why does the car shake violently when it is just started?

The reasons for violent shaking when the car is just started are as follows: 1. Poor fuel quality: Inferior fuel has poor volatility, and the engine block temperature is low when starting a cold car, causing the fuel injected into the cylinder to not fully mix with the air, resulting in difficulty starting and severe body shaking. 2. Carbon deposits in the engine valves and intake pipes: Carbon deposits can absorb an appropriate amount of fuel, causing the electronic control unit to make incorrect judgments, failing to provide the power needed for car startup, leading to shaking. 3. Spark plugs: The gap between the spark plug electrodes gradually increases, the ignition energy decreases, and the fuel atomization is poor, causing the car body to shake immediately after starting.
