What is the wading depth of Volkswagen's dry dual-clutch transmission?

The maximum wading depth for Volkswagen's dry dual-clutch transmission is 150mm. The wading depth of Volkswagen's dry dual-clutch transmission is determined by the vehicle's ground clearance, which is listed in the model's parameter configuration sheet. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, off-road vehicles and SUVs have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a reference when passing through waterlogged roads. If the air intake is below the water level when wading with a Volkswagen dry dual-clutch transmission, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. Installing a snorkel can increase the height of the engine's air intake, thereby improving the maximum wading depth. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the engine from automatically restarting if the vehicle stalls in water, which could lead to severe engine damage due to water intake. Assess the underwater road conditions based on the passage of preceding vehicles and choose an appropriate entry point. Follow the path taken by other vehicles, drive at a low speed, and avoid sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, or other reference points like the wheels and doors of other vehicles to estimate the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half the tire height or the engine's air intake, avoid entering the water and choose an alternative route.

What Does the Driving Test Subject 4 Cover?

Subject 4, also known as the theoretical driving test or driver's theory exam, assesses "driving ethics." The main content includes safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. Below is an introduction to the content of Subject 4: According to the "Order of the Ministry of Public Security of the People's Republic of China," the small vehicle question bank contains 1,240 questions, while the large vehicle question bank has 1,715 questions. Some question types in Subject 4 are extracted from Subject 1, focusing on safe and civilized driving requirements, safe driving skills under complex conditions, and emergency handling knowledge. These are tested after the practical road driving exam (Subject 3) to further evaluate the candidate's traffic awareness. Subject 4 has no limit on the number of attempts. If the first attempt on the day is unsuccessful, an immediate retake is allowed. If still unsuccessful, the candidate must reschedule, with no additional fees for retakes. However, it is important to note that the driving skill test permit is valid for three years. If the candidate fails to complete the test within this period, previously passed subjects will be invalidated. Subject 4 Exam Notes: Exam Duration: The test lasts 45 minutes. Making 12 mistakes (6 questions) will terminate the exam. Question Count: Depending on the license type, 50 questions are randomly selected from the Subject 4 question bank—800 questions for small vehicles and 1,023 for large vehicles. Each question is worth 2 points. Question Types: The exam includes true/false questions (1-20), single-choice questions (20-40), and multiple-choice questions (41-50). Questions may involve animations, images, scenario recognition, or text descriptions. Retake Notes: Failing Subject 4 only requires retaking Subject 4. The driving school schedules retakes, with no limit on attempts and no additional fees. Subject 4 Exam Tips: Strengthen weak areas by identifying mistakes. For marked questions, avoid merely memorizing answers. Instead, consult regulations, textbooks, or reference materials to understand the reasoning behind correct answers. Categorize and summarize questions, referring to the question bank for similar questions. Many questions are easily confused, such as traffic signs for walking, hiking, pedestrian crossings, etc. Grouping them helps avoid errors. Use memory techniques: Many questions involve numbers. Summarizing these numbers aids memorization. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 3 is divided into two parts. Subject 1 covers traffic laws, regulations, and related knowledge; Subject 2 tests field driving skills; and Subject 3 evaluates road driving skills and safe, civilized driving knowledge.

How to Soundproof the Engine Compartment?

There are several methods to soundproof the engine compartment: 1. Install a firewall U-channel in the engine compartment for soundproofing, which requires the use of firewall sandwich foam and damping sound insulation vibration pads. 2. Remove the dashboard in the cabin for soundproofing, which requires the use of damping sound insulation vibration pads, damping sound insulation absorption foam, and polyester fiber cotton. 3. If you do not want to work in the engine compartment or remove the dashboard, you can cut polyester fiber cotton into blocks and use tools to fill them inside the dashboard to make it more solid, thereby achieving the purpose of isolating engine noise.

How to Distinguish Between Domestic Cars and Joint Venture Cars?

The difference between domestic cars and joint venture cars lies in the technology used: domestic cars utilize domestic technology, while joint venture cars employ foreign technology. There are many joint venture brands in China, such as GAC Toyota, FAW Toyota, GAC Honda, Dongfeng Honda, FAW Volkswagen, SAIC Volkswagen, Brilliance BMW, Beijing Benz, and FAW Audi. Taking the Vios FS as an example, it is a compact car under FAW Toyota. In terms of body dimensions, it measures 4140mm in length, 1700mm in width, and 1485mm in height, with a wheelbase of 2550mm. The front face of the car features a large air intake grille with a smoked black design.

How to Deal with Wind Noise?

Methods to handle wind noise include reducing the sealing gaps of the four doors and enhancing the sealing at the joints. You can add sealing strips to the door frames and install soundproofing cotton inside the door panels. For engine noise, you can install soundproofing cotton on the engine cover and wrap soundproofing cotton around the air conditioning pipelines and wiring harnesses. Wind noise occurs when the pressure of oncoming wind exceeds the sealing resistance of the car doors during high-speed driving, entering the vehicle. The faster the speed, the greater the wind noise (mainly generated and transmitted through the sealing gaps of the four doors and the overall thin steel plates).
