What Does Tire Pressure Reset Mean?

Tire pressure reset refers to the operation of resetting the tire pressure monitoring system after addressing a tire pressure fault. Tire pressure reset method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button. Release the button after hearing a "ding" sound. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will turn off, indicating the completion of the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system typically alerts when the pressure is below 1.8 bar or above 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the tire pressure monitoring system will still record the old data, causing the tire pressure monitoring indicator light to remain on. A simple tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation port. If the sensor is damaged during driving, such as by hitting a curb, it can also trigger the tire pressure fault light. In case of sensor damage, the only solution is to replace it with a new one.

How to Check if a Car is New?

Here are the methods to check if a car is new: 1. Check the odometer: When taking delivery of the car, it's normal for the odometer reading of a new car not to be zero. This is because new cars usually undergo testing after production and need to be moved during transportation. If the odometer shows a higher number, there are two possibilities: either the car was driven directly from another location, or it might be a test-drive vehicle. In any case, if the odometer reading is unusually high, you can refuse to take delivery unless the dealership offers a replacement. 2. Inspect the exterior: Examine the entire body for any signs of repainting. Repainted areas will differ from the original paint, and careful observation from different angles can reveal these differences. Additionally, check for fingernail scratches under the four door handles. Test-drive and display cars often have such marks, and even if the dealership attempts to conceal them, they can usually be detected. 3. Check the manufacturing date: The production date is typically indicated on the door plate. Buyers should carefully check for any signs of tampering on the door plate. Besides this location, relevant information can also be found in the engine compartment and on the frame, which should be cross-checked for consistency. Generally, a manufacturing date within three months is considered normal, while anything beyond that may indicate the car is from stock.

Do spark plugs need to be replaced after driving 25,000 kilometers?

Generally, spark plugs do not necessarily need to be replaced after a car has driven 20,000 kilometers. Spark plug replacement cycle: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the instructions in the user manual. You can refer to the following standards for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. How spark plugs work: Under high voltage, the air between the center electrode and the side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark." Along with the heat expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2,000-3,000°C, which is sufficient to ignite the air-fuel mixture in the combustion chamber of the cylinder.

How to Close the Hood of a Corolla?

The method to close the hood of a Corolla is to lower the hood support rod with one hand while holding the hood with the other hand, then slowly lower it. When the hood is about 30 centimeters from closing, release it to let it fall freely. A 'clunk' sound indicates successful closure. Below are additional details about closing the hood of a Corolla: 1. Precautions: Before closing the hood, always ensure the support rod is placed back into its clip. Closing the hood while the support rod is still extended may cause the hood to bend. Check and confirm that the hood is fully closed and locked. If the hood is not properly locked, it may open while driving, leading to serious accidents, injuries, or even fatalities. 2. Function: As the hood is a crucial part of the vehicle, any issues with it can affect normal car usage. Like other car components, the hood serves important functions. Learning the correct way to open and close the hood is essential. Regular maintenance of the hood can prolong its lifespan and prevent disruptions to normal vehicle use due to hood damage.

Can a BMW Key Still Work After Being Soaked in Water?

Key may not work after being soaked in water. If the soaking time is long and the key has short-circuited due to water ingress, it needs to be disassembled and dried to determine if it can still be used. Here is some additional information: 1. Wipe with tissue: If a car key gets wet, it's similar to a phone getting wet—do not press the buttons immediately, as this can cause water to seep into the inner layers faster. Use a dry cloth or tissue to wipe the surface clean, and use highly absorbent tissue to clean the inside. 2. Dry with cold air: Use a hairdryer on the cold setting to dry the key. Never use hot air, as the internal circuit board should not be exposed to high heat. Alternatively, you can place the key in a breathable bag and then into a dry rice container, as rice is highly absorbent and can draw out moisture. 3. Wipe with alcohol: Use a cotton swab dipped in high-concentration alcohol to gently clean the internal button contacts and other parts, as high-concentration alcohol has strong water-absorbing properties.

What to Do When the BMW Fuel Tank Cap Won't Open?

Methods to handle a stuck fuel tank cap: 1. If the fuel tank cap is stuck or rusty: Insert a small wooden piece into the gap of the fuel tank cap to pry it open, remembering to pull the fuel tank cap release switch. 2. If the fuel tank cap spring loses elasticity: You can install a small spring (not too soft or too long) on the protruding rubber pad of the fuel tank to increase the elasticity between the fuel tank cap and the locking mechanism. 3. If the fuel tank cap hinge or latch is worn out: Apply lubricating grease to the hinge and latch of the fuel tank cap. 4. If the fuel tank cap is misaligned: Some cars have thinner sheet metal, which may cause the fuel tank cap to misalign. In this case, visit a repair shop to realign it. 5. If there is a control circuit issue: For cars with remote-controlled fuel tank caps, besides the above issues, the small motor on the fuel tank cap might be burnt out, usually requiring motor replacement. 6. If the fuel tank cap is frozen or too dirty: If the fuel tank cap is stuck due to freezing weather or excessive dirt, clean or thaw it first instead of forcing it open to avoid secondary damage.
