What does SET mean in Volkswagen Bora?

SET in Volkswagen Bora refers to the Tire Pressure Monitoring System. More information about the Tire Pressure Monitoring System is as follows: 1. The Tire Pressure Monitoring System can automatically monitor various conditions of the tires in real time by recording the rotation speed of the tires or through electronic sensors installed in the tires, providing effective safety protection for driving. 2. During driving, the direct tire monitoring system uses tire pressure sensors on the tires to monitor the tire pressure of all four driving wheels. When a loss of pressure is detected, the system will issue a visual or audible alarm. 3. When the tire pressure is too low, the corresponding actual inflation pressure value will be displayed, allowing the selection of standard inflation pressure for partial or full load conditions.

What are the operating procedures for a wheel alignment machine?

Below are the operating procedures for a wheel alignment machine: 1. Check the vehicle's suspension system, wheel bearings, steering system, etc., for any gaps or damage. The maximum allowable tread depth difference for tires on the same axle is 2mm. Ensure the tire inflation pressure meets specifications. The vehicle should be fully equipped to its weight. 2. Drive the vehicle onto the four-post lift and position it stably, aligning the vehicle's center with the center of the lift and turntable. Inspect and, if necessary, modify the vehicle specifications. 3. Strictly follow the steps displayed by the alignment machine; no steps should be omitted. For example, perform wheel runout compensation and tire inspection as required. 4. The adjustment of each wheel's alignment parameters (toe-in, camber angle) should comply with the requirements specified in the vehicle's 'service manual.' Any parameters that do not meet the specified requirements should be adjusted (except for those that cannot be adjusted as per the original vehicle configuration).

How to Fix Scratched Car Paint?

Here are the methods to fix scratched car paint: 1. Generally, the front bumper, rear bumper, and fuel tank cover of a car are made of plastic, and the paint layer is relatively thin. If the scratch is minor and you don’t want to repair it, you can use a touch-up paint pen for treatment. 2. If the scratch is on other parts of the vehicle, such as the door panel, then it depends on the type of paint. If it’s a solid color paint, you can also use a touch-up paint pen, and it usually won’t be noticeable under normal circumstances. 3. If it’s metallic or pearl paint, the scratch will be more visible. In this case, you’ll need to go to a 4S shop for a repainting treatment. Typically, 4S shops repaint the entire panel for such repairs.

Can the Cabin Air Filter Be Reused?

It is not recommended to reuse the cabin air filter in a car. If the cabin air filter is excessively dirty, reusing it is inadvisable because the filter, which appears to be made of paper, actually consists of multiple layers designed for deep filtration. This means that even if the surface of the filter is cleaned, some contaminants may remain trapped between the layers. More details are as follows: 1. If the cabin air filter is dirty and not replaced promptly, prolonged use can lead to unpleasant odors. When the air conditioning is turned on, a musty smell may develop inside the car, which is likely caused by bacterial growth on the filter. 2. When the air conditioning is in use, the cabin air filter can absorb harmful substances from the outside air, protecting both the health of the passengers and the car's air conditioning system. 3. Generally, there are two types of cabin air filters used in cars: a standard filter and an activated carbon filter. The latter is more expensive because it contains activated carbon within its layers, which effectively absorbs impurities and odors from the air conditioning system. 4. If the car is frequently driven in areas with poor environmental conditions, it is advisable to regularly check the condition of the filter. The replacement interval for the cabin air filter should be determined based on the specific usage conditions of the car. If the filter becomes excessively dirty, it is recommended that the owner replace it promptly.

What is the principle of a car horn?

Car horns work by the vibration of a metal diaphragm to produce sound. An automotive electric horn consists of an iron core, a magnetic coil, contacts, an armature, and a diaphragm. Here is a related introduction to car horns: 1. When the driver presses the horn switch, current flows through the contacts to the coil, generating a magnetic force that pulls the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, along with the armature, returns to its original position under its own elasticity and the action of the spring plate, closing the contacts and completing the circuit again. Current flows through the contacts to the coil, generating magnetic force, and the process repeats. 2. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound. The resonance board, rigidly connected to the diaphragm, makes the sound smoother and more pleasant (i.e., the principle of an electromagnet).

Is it necessary to go to the 4S store where the car was purchased for maintenance?

Car maintenance does not necessarily have to be done at the 4S store where the car was purchased. Any 4S store nationwide that matches the car model brand is acceptable. Typically, car warranty policies are mostly for 2 years or 60,000 kilometers (whichever comes first), with some models having slightly longer warranty periods, but generally not exceeding 5 years or 100,000 kilometers. Relevant information about car maintenance is as follows: 1. Car maintenance (Car-maintenance), also known as car servicing, refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car. 2. Car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, and extend the service life.
