Restarting the engine after stalling in water does not necessarily mean water will enter the engine. It is commonly believed that when a vehicle drives through water, a large amount of water can be sucked into the combustion chamber through the air intake. During the compression stroke, the water, being less compressible than air, can block the piston. If the engine is restarted, the powerful rotational force may not overcome the compression resistance, potentially leading to a bent connecting rod. Below is relevant information about vehicle water damage insurance: 1. Important Notes: If engine damage is caused by human actions, such as restarting the engine after stalling in water, insurance companies will not cover the damage even if the policy includes water damage coverage. 2. Coverage Details: Rescue costs, cleaning expenses, electrical damage, and interior component damage are covered under comprehensive auto insurance, while only engine damage is covered under water damage insurance. Most insurance companies impose a 15%–20% absolute deductible on water damage claims. This means that even with comprehensive insurance, water damage coverage, and additional no-deductible riders, the maximum reimbursement for engine damage is limited to 80%–85%.

Do I need to bring photos when getting a driver's license for the first time?

First-time applicants for a driver's license do not need to bring photos. The photos submitted when registering for driving lessons are used not only in the driving school records but also for the driver's license itself. Below are some precautions for first-time license holders (probationary period): 1. Follow the rules: Adhere to traffic regulations, avoid excessive speed, and minimize traffic violations, fines, and penalty points. 2. No solo highway driving: Do not drive on highways alone; an experienced driver must accompany you. 3. Display probationary signage: A standardized probationary sign must be affixed or hung at the rear of the vehicle. 4. Points to note: For a Class C license, a maximum of 11 points can be deducted; exceeding 12 points will result in license revocation. For Class AB licenses, a maximum of 5 points can be deducted; exceeding 6 points extends the probationary period by one year, and exceeding 12 points revokes the driving qualification for the probationary vehicle class.

What causes Toyota P1603 engine stall and shutdown?

Toyota P1603 engine stall and shutdown can be caused by engine stall failure or transmission failure. The following are the relevant reasons: Engine failure: The engine control module, also known as the engine control unit (in some vehicles, the engine control module and transmission control module are integrated into a powertrain control module), controls the operation of the entire engine. Its main function is to control the optimal fuel injection amount and ignition timing. Another important role is to monitor the components of exhaust emission control. Transmission failure: The main cause of transmission failure is often a dirty valve body. A dirty transmission valve body can degrade the quality and friction characteristics of the transmission fluid. This increases friction and wear, and sludge can also form inside the transmission, leading to blockages in the valve body and pipelines. This disrupts the proper regulation of hydraulic pressure, resulting in transmission problems.

What does 'Brake Servo System Function Limited' mean in Audi?

Audi dashboard displays 'Brake Servo System Function Limited' indicating a fault in the vehicle's braking system, such as excessive brake pad wear or water ingress. You may continue driving to see if the warning disappears. If it persists, it is recommended to visit a 4S store for code reading and troubleshooting. Below is an introduction to this system: 1. Overview: This braking system is formed by adding a power servo system to the manual hydraulic braking system. Under normal circumstances, most of the braking energy is supplied by the power servo system. In case of servo system failure, it can still rely entirely on the driver's input. 2. Types: Servo braking systems can be divided into two categories: booster type and supercharging type. The booster type, also known as direct control type, features a servo system control device (control valve) directly operated by the brake pedal mechanism. The vacuum servo chamber generates assistance that works together with pedal force on the brake master cylinder to supplement pedal force. Passenger vehicles commonly use vacuum booster servo braking systems.

Is it necessary to warm up the car before starting a new vehicle?

It is necessary to warm up a new car before starting it. Here are the reasons why warming up is required: Lack of lubrication in a cold engine: After the car has been parked for a long time, the engine oil flows back into the oil pan at the bottom of the engine. Therefore, when starting the engine after a long period of inactivity (such as overnight), the upper part of the engine is without oil and lacks lubrication. It takes about 10 seconds after starting for the oil pump to circulate the oil to the parts of the engine that need lubrication the most, such as the pistons, connecting rods, and crankshaft. Effective vaporization of gasoline: Before the engine reaches its operating temperature (approximately between 90-110 degrees Celsius), the fuel supply system cannot effectively vaporize the gasoline completely due to the low temperature. When the gasoline is not vaporized and remains in a "wet" liquid state, it is difficult to ignite and start the engine.

What is the wading depth of the all-new 2020 Sagitar?

The maximum wading depth of the Sagitar is 70 cm, while the safe wading depth is 31 cm. Additional information: Advantages of the Sagitar: 1. Interior materials: Although the Sagitar is not positioned as a high-end model, the dashboard is still wrapped in soft materials, giving it a sense of premium quality. 2. Spacious seating: For a passenger who is 180 cm tall, the front headroom exceeds three fingers, while the rear legroom is about two fists. The rear headroom is slightly cramped, measuring only about two fingers. Car enthusiasts have noted that this level of space is sufficient for family use. 3. Practical trunk: The trunk has a standard capacity of 510L, which is ample for household needs. Additionally, the rear seats can be folded down proportionally using the handles inside the trunk, enhancing convenience. Furthermore, the rear armrest area can be connected to the trunk, further improving practicality.

Difference between Parking Brake and Service Brake

Stoppers are brakes, while the parking brake should actually be called the parking brake system. This device is the handbrake system, which is not used to slow down the vehicle during driving but to keep the vehicle stationary after parking. The brake system is used to slow down the vehicle while driving. The brake system is a very important system in a car, as it relates to the driving stability and safety of the vehicle. The following are the functions of the brake system: Service Brake: During driving, the service brake (foot brake) is generally used to slow down the car or stop it in the shortest distance; it also helps maintain a stable speed when driving downhill. Parking Brake: The parking brake is not only used to keep the car stationary but can also be used when the service brake fails. Once the car is parked, the parking brake (handbrake) should be applied to prevent the vehicle from sliding forward or rolling backward.
