Audi A3 common faults include transmission failure, automatic start-stop failure, frequent ABS pump failure, interior odor, brake noise, and reverse gear shaking. Common faults of Audi A3: Transmission failure symptoms: Abnormal noise, specifically a metal friction sound from the left side of the engine, referred to as 'sheep calling' by 4S shops. Automatic start-stop failure symptoms: Displays as unavailable. Reasons such as not wearing a seatbelt can trigger this fault. Frequent ABS pump failure symptoms: ABS light turns on, indicating ABS pump damage. Interior odor symptoms: Occasional burnt smell inside the car. Brake noise symptoms: Squeaking noise when braking during slow starts with a cold engine. Reverse gear shaking symptoms: Engine shakes when braking in reverse. Audi A3 failure rate: The failure rate of the Audi A3 is not very high; it is lower than many joint-venture models in the same price range. As a luxury brand, Audi has strong brand competitiveness. The A3, as an entry-level model of Audi, fulfills many people's dream of owning a luxury car, making it relatively cost-effective.

I've been driving an Audi A3 for three years and have personally experienced several common issues. For example, the engine makes particularly loud noises during cold starts, which was found to be caused by aging turbocharger components. The air conditioning system also occasionally fails, possibly due to refrigerant leaks or clogged pipes, making repairs quite annoying. Electronic sensors are prone to false alarms, with warning lights frequently appearing on the dashboard. Once, the ABS anti-lock braking system malfunctioned, nearly affecting brake response, but fortunately, the sensor was replaced in time. The suspension system wears out quickly on rough roads, and the shock absorbers start making noises after prolonged use. Overall, while these issues aren't critical, regular maintenance is recommended to prevent minor problems from turning into major expenses.

What are the penalty standards for oncoming vehicle encounters?

Introduction to the rules for oncoming vehicle encounters in Subject 3: 1. When encountering an oncoming vehicle on a road without central isolation facilities or a centerline, failure to slow down and drive on the right side, or failure to maintain a safe distance from other vehicles, pedestrians, or non-motorized vehicles will result in a 100-point deduction; 2. Failure to yield when encountering difficulties in passing will result in a 100-point deduction; 3. Poor judgment of lateral safety distance, leading to emergency steering to avoid the oncoming vehicle, will result in a 100-point deduction. Before encountering an oncoming vehicle, you should follow the 'look, calculate, and slow down' principle: 1. 'Look' means to observe carefully. The observation should include: the type, speed, and load of the oncoming vehicle; the width and condition of the road; pedestrians, vehicles, and obstacles on the roadside; whether there are any oncoming vehicles ahead or vehicles behind trying to overtake. 2. 'Calculate' means to estimate the approximate meeting point by observing the distance and speed of both vehicles, and to choose a suitable meeting point by controlling your own speed. Suitable meeting points should be: a. where the road is wider; if the road width is limited, choose a wider area where both vehicles can ensure safety; b. where there are no obstacles on the right front of both vehicles. 3. 'Slow down' means to reduce speed. If conditions are poor when approaching the meeting point, you should further reduce speed and avoid reckless passing. If necessary, stop first to ensure a smooth encounter between the two vehicles.

Can You Start Learning Subject 2 Only After Passing Subject 1?

After completing Subject 1, you can start learning Subject 2 according to the driving school's arrangement. The exam for Subject 2 can be scheduled online 10 days after passing Subject 1. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the registration requirement for Subject 2 is completing 26 class hours, including 2 hours of theoretical knowledge, 3 hours of simulated driving, and 21 hours of practical training. For a C1 driver's license, the Subject 2 exam can be scheduled online 10 days after passing Subject 1. For each Subject 2 exam appointment, you have two attempts. If you fail the first attempt, you can retake it for free. If you do not take the retest or fail the retest, the exam ends, and you can reschedule the Subject 2 exam after 10 days. Within the validity period of the driving license learning, the number of Subject 2 exam appointments must not exceed five. If you fail the fifth appointment, the results of other previously passed subjects will be invalidated. To continue learning for the driving license, you must restart from Subject 1. Subject 2 Exam Content: Driving a motor vehicle within a designated area to complete the exam tasks; demonstrating mastery of vehicle driving skills; and assessing the ability to judge the spatial position of the vehicle. Subject 2, also known as the small road test, includes five mandatory tasks: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving. Subject 2 Exam Tips: After getting into the car, adjust the seat and rearview mirrors to a suitable position and state, and always fasten your seatbelt. For parallel parking, remember to find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the vehicle's speed. When stopping on a slope, remember to engage the handbrake. When starting, signal with the left turn light, release the handbrake, stabilize the clutch, and gently press the accelerator while releasing the clutch to avoid stalling or rolling back. For right-angle turns, identify the turning point quickly and react accordingly, coordinating with the vehicle speed to prevent deviation. For curve driving (S-turns), slow down and proceed cautiously. Those with good driving sense during practice can pass through smoothly in one go. For reverse parking, control the speed carefully, identify reference points accurately, and make minor adjustments if deviations are observed in the rearview mirror. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the exam on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skills test. Subject 3 is divided into 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, in official terms (i.e., the Ministry of Public Security's Order No. 123), there is no such thing as Subject 4.

How many subjects are there in the car driving license test?

Four subjects. Subject 1 is a written test. Subject 2 is called the small road test. Subject 3 is called the big road test. Subject 4 is also a theoretical test. Here are the details: Subject 1: Road traffic safety laws, regulations, and related knowledge test. The structure of the test question bank and basic question types are formulated by the Ministry of Public Security, and the traffic management departments of provincial public security authorities establish the test question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. Subject 2: Field driving skills test. The test items include: reversing into a parking space, stopping and starting on a slope, turning at a right angle, driving on a curve, and parallel parking. In cities like Shanghai, Subject 2 consists of nine mandatory items: reversing into a parking space, turning at a right angle, parallel parking, driving through a tunnel, stopping to take a card, driving on a curve, making a U-turn on a narrow road, emergency stopping, and stopping and starting on a slope. Subject 3: Road driving skills test. The basic test items include: preparing to start, starting, driving straight, changing lanes, passing through intersections, pulling over, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting oncoming vehicles, overtaking, making U-turns, and driving at night. Subject 4: Safe and civilized driving knowledge. The test items include: knowledge related to safe and civilized driving. Before learning to drive, you should also undergo a physical examination, as follows: Physical examination items as stipulated in Article 11 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses": Height: Applicants for large buses, tractors, city buses, large trucks, or trolleybuses must be at least 155 cm tall. Applicants for medium-sized buses must be at least 150 cm tall. Vision: Applicants for large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or trams must have uncorrected or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart. Applicants for other vehicle types must have uncorrected or corrected visual acuity of at least 4.9 on the logarithmic visual acuity chart. Color vision: No red-green color blindness. Hearing: Able to distinguish the direction of sound sources with each ear 50 cm away from a tuning fork. Upper limbs: Both thumbs must be intact, and each hand must have at least three other fingers intact, with normal limb and finger movement functions. Lower limbs: Normal movement function. Applicants for manual transmission vehicles must have a leg length difference of no more than 5 cm. Applicants for automatic transmission vehicles must have a sound right lower limb. Torso and neck: No movement dysfunction. Notes: Each test subject has two attempts. If both attempts fail, you must reschedule the next test, usually with a 10-day interval. The test validity period is three years, meaning you must complete all tests within three years after passing Subject 1. Otherwise, the previous test results will be automatically invalidated, and you will need to reapply to a driving school.

How many points are deducted for making a U-turn over double solid yellow lines?

Making a U-turn over double solid lines is a traffic violation. According to Article 93 of the Road Traffic Safety Law, violators will be fined 200 yuan and receive 3 penalty points. On long roads, solid white lines are usually present in the middle section or before intersections. If the lines are yellow dashed or white dashed, U-turns are allowed. However, U-turns are strictly prohibited over any solid lines. Permissible U-turn situations: If there is a clear U-turn sign at an intersection, U-turns are allowed. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, make a U-turn based on the specific situation, ensuring it does not obstruct other vehicles or pedestrians. U-turns are allowed at intersections without explicit "No U-turn" or "No Left Turn" signs: If there are no signs explicitly prohibiting U-turns, you can perform a U-turn. "No explicit prohibition" means the intersection lacks signs like "No U-turn," "No Left Turn," or solid center lines. In such cases, U-turns are permitted. U-turns are also allowed over yellow grid lines: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary stops, important facility entrances, or other designated areas. Stopping on these grid lines (including waiting for traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed as long as there are no central barriers. Yellow grid lines without barriers are equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, follow it. U-turns are only allowed when the light is green. When "No Left Turn" and "U-turn Permitted" signs appear together: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Precautions when making U-turns at intersections: Observe road markings. If the lines are solid, U-turns are prohibited under any circumstances. Continue driving to find a suitable U-turn location. If there is a "No Left Turn" sign ahead, U-turns are also prohibited at that intersection, even if there is no explicit "No U-turn" sign. This is because U-turns and left turns involve similar movements, and a U-turn always requires a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not allowed at that intersection. Always yield to oncoming traffic when making a U-turn. Perform the maneuver only if it does not interfere with the normal flow of traffic. Otherwise, you will bear full responsibility for any accidents. Near intersection stop lines, lanes usually have guiding arrows for vehicle direction. The leftmost lane may not always have a left-turn arrow. If a straight arrow is present, U-turns are prohibited even if there are no explicit "No U-turn" signs. U-turns are not allowed on pedestrian crosswalks and are considered traffic violations.

Why is the production capacity of BYD DM-i unable to meet demand?

Introduction to the reasons why BYD DM-i production capacity cannot keep up: 1. The powertrain and dedicated Blade Battery for DM-i models require specialized production lines, but establishing/renovating production lines requires capital and time; 2. Limited by the supply of components from suppliers. The Xiaoyun powertrain used in DM-i models and the dedicated Blade Battery require independent production lines, which cannot be met through simple adjustments of existing production lines (pure electric or DM-p model production lines). Therefore, BYD must establish new production lines or renovate existing ones to meet production supply.
