Volkswagen New Polo's spark plug model is Bosch F7HER2. The spark plug material is nickel alloy. When the vehicle reaches a certain mileage, the spark plug may develop issues such as carbon deposits and increased electrode gap. Carbon deposits can lead to increased fuel consumption, while an enlarged spark plug gap may cause insufficient ignition energy, resulting in difficulty starting the engine. Therefore, regular inspection and maintenance of the spark plug can extend the engine's lifespan. Below are precautions for using spark plugs in Volkswagen New Polo: 1. Avoid long-term neglect of carbon deposit cleaning. During use, normal carbon deposits will accumulate on the electrode and skirt insulator of the spark plug. If these deposits are not cleaned for a long time, they will accumulate more and more, eventually leading to electrode leakage or even failure to spark. 2. Avoid prolonged use. There are many types of spark plugs, each with its own economic lifespan. Continuing to use them beyond this lifespan will adversely affect the engine's power and fuel efficiency.

What does the key icon in the car mean?

When the key icon appears on the car dashboard, it may indicate one of three situations: first, the remote key battery is low; second, the smart key is not within the sensing range; third, there is an issue with the car's smart sensing system. It is recommended that car owners use the process of elimination to identify the cause and address it promptly to avoid affecting vehicle usage. Below are some relevant tips for car key maintenance: 1. During the use of the car, it is important to protect the remote key. Do not expose the key to environments below 0°C or above 50°C, as this will significantly reduce the battery's lifespan. 2. Keep the key in a dry environment, as humidity can decrease battery life. Avoid placing the key with hard objects to prevent scratching the chrome plating on the key. 3. Do not place the key near high-power appliances such as TVs, microwaves, washing machines, or computers, as this may cause the key to malfunction.

What is the working principle of a car speed sensor?

The working principle of a car speed sensor is: The output signal of the speed sensor can be a magnetoelectric AC signal. The speed sensor is usually installed in the drive axle housing or transmission housing, displaying the vehicle's speed through pointer swings or generating alternating current signals. It typically consists of a magnetic core and coil with two terminal posts. These two coil terminal posts are the output terminals of the sensor, converting into current amplitude to represent the vehicle speed. More information about the speed sensor is as follows: 1. The speed sensor is a device used to detect the speed of electronically controlled vehicles. The control computer uses this input signal to control engine idle speed, torque converter lock-up in automatic transmissions, automatic transmission shifting, and other functions such as the opening and closing of the engine cooling fan and cruise control. 2. The magnetoelectric speed sensor is an analog AC signal generator, usually composed of a magnetic core and coil with two terminal posts.

What are the methods to deal with stubborn water stains on car glass?

There are 6 methods to deal with stubborn water stains on car glass: 1. Use toothpaste: Apply toothpaste to remove water stains. Take an appropriate amount of toothpaste, apply it to the water stains, and then wipe with a soft towel. Repeat several times and rinse with water; 2. Use cleaning clay: Purchase a piece of cleaning clay and use it before washing the car. Wait for the car to dry, and there will be no water stains. It can also remove asphalt spots; 3. Use detergent: Dishwashing detergent used in the kitchen can also remove stubborn water stains. Apply an appropriate amount of detergent to the stains, use a cleaning sponge to wipe, and rinse multiple times; 4. Use hydrochloric acid: Buy some hydrochloric acid, dilute it with a plastic container, and then use a plastic brush. After a while, it can be rinsed off with water. If there are still stains, wipe again with diluted hydrochloric acid and then rinse with clean water; 5. Use a glass scraper, water squeegee, bubble-free glass cleaner, and strong all-purpose cleaner: Thoroughly remove dirt, including cleaning the window frames and their protective film, vacuum the interior of the window gaps, and especially use a glass knife to remove stubborn cement spots or adhesive spots. The cleaning solution contains anti-static ingredients, making the wiped glass crystal clear and less likely to attract dust; 6. Use shampoo or water from washing hair: Mix a spoonful of shampoo with a little water or use the water from washing hair, wipe the stained areas with a cloth, and then dry with a dry cloth or paper.

What is the reason for the non-responsive headlight adjustment of the Xiali N5?

Xiali N5 headlight adjustment not responding may be due to stripped screws, which need to be replaced. The screws are located at the back of the headlight. Different flashing patterns of the headlight indicate different meanings. Details are as follows: 1. Flash once or twice: At intersections, when the light turns green, sometimes the car in front may not move. This could be due to the driver being a nervous beginner, slow to start, or not noticing the traffic light change. In such cases, the following car usually takes some action to alert the driver ahead. Many choose to honk repeatedly, but this might have the opposite effect. Instead, flashing the headlight once or twice can remind the driver ahead, but avoid doing it too frequently. 2. Flash twice: When approaching an oncoming car from a distance, flashing the headlight twice reminds the other driver to switch to low beams. If there's no response, you can also briefly turn on the high beams and then quickly turn them off to alert the oncoming driver to change their lights. 3. Flash three times with a horn: If you notice issues like a flat tire, an open trunk, or other problems with another car, flash your headlight three times and honk to alert them to pull over and check. 4. One flash for 'agree,' continuous flashing for 'disagree': If a car behind signals to overtake, one flash indicates agreement, while continuous flashing means refusal. This helps the following car understand your response and decide whether to proceed with overtaking.

What to Pay Attention to When Replacing a Car Battery?

Precautions for replacing the battery are as follows: 1. Before installing a new battery, if the brand and model of the battery are inconsistent, compare the external dimensions and terminal positions of the old and new batteries, and carefully check the battery's capacity and cold cranking amperage (CCA) parameters. Especially in northern winters, if the CCA does not match, it may cause difficulty in starting the vehicle. 2. If conditions permit, use a battery tester for testing. Some batteries, after being stored for a long time, may show a voltage above 12V between the positive and negative terminals, but actually have insufficient capacity, known as "false voltage." Such batteries need to be charged. 3. Place the new battery in the installation position and secure it. For batteries with vent tubes, do not forget to remove the vent tube connector from the old battery and install it on the new one. For lead-acid batteries, ensure that the tilt angle does not exceed 30° during installation. 4. When connecting the battery terminals, connect the positive terminal first, followed by the negative terminal. After installation, you can spray anti-rust protectant or acid-free grease on the battery terminals for protection.

What does it mean when the EPC light comes on in the car?

Possible reasons for the EPC light being on: The car's throttle is dirty and needs cleaning. Brake system malfunction, in which case the brake light also won't illuminate. Fuel quality issues can trigger the EPC warning light. EPC (Electronic Power Control) stands for Engine Electronic Power Control System. When a sensor fails or detects abnormal conditions, the control system will take corresponding measures according to preset programs. The following situations may cause the EPC light to come on: Engine intake system failure, throttle failure, fuel system failure, Engine malfunction, ECU control unit failure, brake light failure. Solutions for EPC light illumination: Troubleshoot intake system issues, use qualified fuel, clean throttle body, etc. Remove carbon deposits and clean relevant components. Re-flash related data (this applies when other troubleshooting methods fail to resolve the issue). Other potential faults cannot be ruled out; specific diagnosis should be based on actual vehicle inspection results before proceeding with repairs. When encountering EPC light illumination, follow these steps: Restart the vehicle after turning it off and check the EPC light. If it doesn't come on, there's likely no issue - occasionally the EPC light may illuminate due to external interference. If the EPC light frequently comes on over a period, first check whether the brake lights are functioning. If brake lights don't work, inspect the brake switch, bulbs, and wiring (sometimes a burnt-out brake bulb may cause this - simply replacing the bulb may solve it). If the EPC light remains on after checking the brake lights, visit a 4S shop for inspection. Common EPC indicator colors are typically two types: yellow and red. A yellow EPC warning light with normal vehicle operation means you should drive slowly to a repair point. A red EPC fault light indicates a more serious situation - immediately pull over and contact maintenance personnel. Continued driving may directly affect core vehicle components or driving safety.
