Why can't the Volkswagen car key be remotely controlled after replacing the battery?

What are the main components of a car's power system?

The automotive power system mainly consists of a battery, alternator, and voltage regulator. The alternator is responsible for charging the battery to maintain it in a fully charged state over time, while both the battery and alternator supply power to all electrical components in the vehicle. Below are detailed explanations: 1. The battery is an essential part of a car, which can be categorized into traditional lead-acid batteries and maintenance-free batteries. Since lead-calcium alloy is used for the grid frame in these batteries, water decomposition during charging is minimal, resulting in low water evaporation. 2. The alternator serves as the primary power source of the vehicle. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally (above idle speed), while simultaneously charging the battery. 3. The voltage regulator is necessary because the alternator is driven by the car's engine, whose speed is not constant. This leads to unstable output voltage from the alternator, hence requiring an electronic device to control the alternator.

Which One is the Fog Light on a Car?

Fog lights are generally located below the car's headlights, and the fog light button is on the left side of the steering wheel, above the headlight switch on the body panel. Here are the details: 1. Car fog lights can increase the running distance and improve the visibility of the driver and surrounding traffic participants, allowing oncoming vehicles and pedestrians to spot each other from a farther distance. 2. Fog lights are divided into front fog lights and rear fog lights. Front fog lights are usually bright yellow, while rear fog lights are red. 3. The symbol for the rear fog light is slightly different from that of the front fog light. The front fog light symbol has downward light lines, while the rear fog light symbol has parallel lines, generally located on the dashboard inside the car.

What is the Difference Between 2.0L and 2.5L Car Engines?

The differences between 2.0L and 2.5L car engines are as follows: 1. Power Output: A 2.0L engine has a smaller displacement compared to a 2.5L engine. A larger displacement means the engine can release more energy per unit time, resulting in better performance. Therefore, a 2.0L engine delivers less power than a 2.5L engine. 2. Fuel Consumption: Due to its smaller displacement, a 2.0L engine consumes less fuel than a 2.5L engine when traveling the same distance. Additional details are as follows: 1. Turbocharging technology was not initially developed for car engines; it was first used in aircraft engines. Turbocharging helps address the issue of insufficient air intake in aircraft engines at high altitudes. 2. Later, turbocharging technology was widely adopted in both gasoline and diesel car engines. Turbocharging allows for increased air intake without increasing the engine's displacement.

Will a Car Get Damaged by Sun Exposure?

It is rare for a car to be damaged by sun exposure. Here are the effects of prolonged exposure to sunlight: Vehicle Aging: Extended exposure to sunlight can accelerate the aging of plastic components in the vehicle. Examples include the dashboard with numerous wiring, car doors, and the sealing rings around the sunroof. Particularly, sealing rings are prone to aging and cracking after prolonged sun exposure, significantly reducing their sealing performance, which may lead to water leakage or seepage. Significant Safety Hazards: Flammable items should not be left inside the car, especially lighters. Lighters exposed to prolonged sunlight inside the car may explode, posing serious safety risks.

How Long Can a Vehicle Go Without Inspection?

A vehicle can go without inspection for up to three months. If the inspection is overdue for less than three months, you can simply make up for it and will receive a verbal warning without a fine. If the inspection is overdue for more than three months but less than two years, you will need to pay a fine and receive a 3-point penalty. If the vehicle has not been inspected for more than two years, its registration file will be canceled. A vehicle is considered overdue for inspection once it exceeds the validity period of the inspection. Vehicle inspections can be conducted up to three months in advance. If a vehicle is driven on the road without undergoing the required periodic safety inspection, a 3-point penalty will be imposed, along with a warning or fine. According to Article 49 of the "Regulations on the Registration of Motor Vehicles": The owner of a motor vehicle may apply for an inspection compliance mark at the vehicle management office of the registration location up to three months before the expiration of the inspection validity period. According to Article 90 of the "Road Traffic Safety Law of the People's Republic of China": If a motor vehicle driver violates the road traffic safety laws or regulations regarding road traffic rules, they shall be given a warning or fined. If other provisions of this law apply, penalties shall be imposed accordingly. According to Article 16 of the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China": Motor vehicles shall undergo safety inspections at the following intervals from the date of registration: Passenger vehicles for commercial use must be inspected once a year within the first 5 years; after 5 years, once every 6 months; trucks and large or medium-sized non-commercial passenger vehicles must be inspected once a year within the first 10 years; after 10 years, once every 6 months; small and mini non-commercial passenger vehicles must be inspected once every 2 years within the first 6 years; after 6 years, once a year; after 15 years, once every 6 months; motorcycles must be inspected once every 2 years within the first 4 years; after 4 years, once a year; tractors and other motor vehicles must be inspected once a year. If a commercial motor vehicle passes the safety inspection within the specified inspection period, it does not need to undergo another safety inspection.

What brand is Atrezzo tires?

Atrezzo is a renowned tire tread series product under the Sailun brand. This series of tires, whether on dry surfaces or muddy roads, features a unique tread design, robust tire shoulders, and a special formula in the tire materials, enhancing the tire's handling performance and braking characteristics. The company's predecessor was the Qingdao Sailun Radial Tire Information Production Demonstration Base Co., Ltd., established on November 18, 2002, located in the Fuyuan Industrial Park, Qingdao Economic and Technological Development Zone, covering an area of approximately 611 acres. It is a domestic brand. However, unlike other domestic brands, Sailun focuses on a globalized industrial layout, having established factories in Qingdao, Dongying, and Shenyang, and sales centers in the Americas, Europe, Australia, and other regions. Methods for tire maintenance: Enhance awareness of tire safety and inspect tires more frequently. Regularly correct wheel balance; unbalanced wheels can cause high-frequency oscillations during high-speed driving, leading to uneven tire wear. Perform regular tire rotation. To ensure even wear on all tires of the same vehicle, rotate the tires every 5,000 kilometers. In daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves gradually become shallow. If the tread is worn flat, it will lose its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks can be potential hazards for tire blowouts during high-speed driving. Additionally, immediately remove pebbles from the grooves. Park on flat ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this operation accelerates tire wear. Do not splash water for cooling. In hot weather or during high-speed driving, tires are prone to overheating, and pressure increases. In such cases, stop to dissipate heat. Never release air to reduce pressure or splash water to cool down, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and emergency stops to prevent accelerated tread wear due to dragging between the tire and the ground.
