What are the precautions for buying a car in full payment at a 4S store?

Precautions for buying a car in full payment at a 4S store include determining the ex-factory price, being cautious with free gifts, verifying the chassis number upon pickup, and inspecting the engine compartment. Determine the ex-factory price: When buying a car in full payment, consumers need to understand the ex-factory price. Generally, 4S stores do not force buyers to purchase insurance or other fees when paying in full, so consumers should negotiate based on the ex-factory price. Be cautious with free gifts: During price negotiations, 4S store salespeople may offer free gifts, which are usually inexpensive. If possible, consumers can request the value of the gifts to be deducted from the ex-factory price, making a price reduction more beneficial. Verify the chassis number upon pickup: When picking up the car, ensure the chassis number matches the code on the certificate of conformity. Check the production date of the car; a reasonable range is 3-6 months. Cars older than one year are not recommended for purchase. Inspect the engine compartment: Open the hood to check if the engine compartment is clean. Start the car for a few minutes, pull out the oil dipstick to check if the oil level and condition are normal, and inspect for any oil stains under the engine compartment.

Can the Car Film Provided by 4S Stores Be Used?

If it is some low-quality car film, it is better not to use it. If it is a product from a reputable brand with good quality, it can be used. Nowadays, many 4S stores offer gifts to customers after purchasing a car, such as floor mats, car films, and some car electronics. It is essential to carefully check whether the floor mats, films, and other products provided by the 4S store are high-quality and compliant. If they are inferior products, it is better not to install them in the car. Inferior films and floor mats can release toxic substances, affecting the health of passengers. Moreover, poor-quality films can significantly compromise driving safety, as their light transmittance does not meet standards, which can be hazardous during night driving. Inferior films also fail to block UV rays and provide heat insulation, accelerating the aging of the car's interior when parked under direct sunlight. It is recommended to purchase a high-quality film from a reputable brand after buying a car. Good-quality films can provide heat insulation and UV protection, safeguarding the car's interior. Additionally, premium films last longer and do not release harmful substances. High-quality car films have excellent light transmittance, ensuring safe night driving. When applying the film, it is advisable not to install it on the front windshield, as the windshield already has UV protection, and applying film there can impair driving visibility.

What kind of engine oil is usually used for the first free maintenance at a 4S dealership?

For the first free maintenance at a car 4S dealership, original equipment manufacturer (OEM) engine oil is typically used. In fact, OEM engine oil is produced by oil manufacturers according to the requirements of the car manufacturers. The first maintenance period for a new car is usually determined by either the mileage or the specified time interval, whichever comes first. Therefore, if the time interval is reached but the mileage is insufficient, the first maintenance should still be performed. Otherwise, the 4S dealership may claim that the standard has not been met, resulting in the information not being recorded in the nationwide warranty system, leading to the loss of warranty coverage. Precautions for the first car maintenance: In addition to changing the engine oil and oil filter, the first maintenance includes a comprehensive inspection and diagnosis of the vehicle's condition and usage. Typically, the first maintenance items are free of charge. If the technician recommends services not included in the first maintenance, the car owner should inquire whether there will be additional charges before deciding whether to proceed. As long as the new car undergoes its first maintenance at the 4S dealership within the specified period, it will still be eligible for the three-guarantee service even if subsequent maintenance is performed elsewhere. However, if the new car owner fails to have the first maintenance performed at the designated 4S dealership or the manufacturer's authorized service station within the specified mileage, any issues that arise with the car, even within the warranty period, may require the owner to pay certain repair costs.

Can front and rear fog lights be turned on together?

Front fog lights and rear fog lights can be turned on simultaneously. On the vehicle's lighting combination switch, there are distinct symbols for front and rear fog lights. The front fog light symbol features three downward-slanting lines on the left side of the bulb icon, while the rear fog light symbol shows three horizontal lines on the right side of the bulb. When driving in rainy or foggy conditions, it is essential to activate both front and rear fog lights to alert other vehicles and prevent potential safety hazards. Procedure for turning on both fog lights: Start the vehicle's power supply; Rotate the knob on the left panel of the steering wheel to the low beam position; Pull the knob outward one notch to activate front fog lights; Pull the knob outward two notches to simultaneously activate both front and rear fog lights. Light sources of fog lights: Generally, front fog lights use halogen or LED bulbs with yellow light, mounted near the ground on the front bumper. The beam angle must be properly adjusted - neither too low nor too high, as improper angles may obstruct the vision of oncoming drivers. Rear fog lights typically use red halogen bulbs. Installation positions vary by model, with some mounted near the ground on the rear bumper and others integrated into the rear taillight assembly. Important note: Fog lights should not be used as regular daytime running lights. Due to their high penetrating power, fog lights should only be used when necessary, as they can significantly impair other drivers' visibility when used inappropriately.

How to Replace Car Spark Plugs?

Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage ignition wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any leaves, dust, or debris on the exterior and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage ignition wires according to the firing order, and then secure the cover plate. If the spark plugs are damaged, they can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most notably, difficulty in starting, which affects the vehicle's normal operation. Severe spark plug erosion, such as pitting, damage, or melted electrodes, indicates that the spark plugs are ruined and should be replaced. Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the owner's manual. The following standards can be used as a reference for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

What Causes the Volkswagen Magotan to Shake During Startup?

The main reasons for severe shaking during the startup of a Volkswagen Magotan include severe carbon buildup in the throttle body, fuel injectors, and intake manifold; significant carbon deposits inside the engine; ignition system failure; unstable oil pressure; and aging engine components. When carbon buildup is severe, it is essential to promptly inspect and clean it. Developing a habit of regular carbon cleaning or allowing the carbon deposits to saturate with absorbed gasoline is advisable. The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon inside the engine, the gasoline sprayed by the cold-start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This causes the engine's combustible mixture to fluctuate between lean and rich, leading to idle shaking after a cold start. The lower the temperature, the more fuel is required for a cold start, so severe carbon buildup can significantly affect startup performance. If the ignition system malfunctions, it is necessary to promptly visit a repair shop for inspection and repair. Insufficient engine temperature, inadequate fuel and lubricant temperatures, and prolonged vehicle use can cause the spark plug's ignition gap to widen, reducing ignition energy and affecting engine performance, leading to shaking. When oil pressure is unstable, it is essential to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor, among other components. If the fuel pump's supply pressure is abnormal or the intake pressure sensor readings are incorrect, corresponding repairs should be carried out. Aging engine components should be replaced, and it is important to develop a habit of regular inspections and timely replacements. Aging engine components are often related to worn engine mounts. Engine mounts act as the engine's shock absorption system, absorbing minor vibrations during operation. If they fail, the vibrations can transfer to the steering wheel and the cabin, causing shaking during idle.
