How to Repair Car Scratches?

Here are some tips for repairing car scratches: 1. Sandpaper polishing. Using sandpaper can also remove minor scratches on the car. Just prepare a piece of sandpaper, clean and dry the scratched area first, then gently rub the scratched area with the sandpaper dipped in water. Be sure to control the rubbing force and avoid rubbing for too long. 2. Iced cola repair. Pour a little cola onto a cloth and repeatedly wipe the scratched area. After several wipes, the scratch marks will gradually lighten. Repeating this process multiple times will yield better results. 3. Essential balm repair. The method is similar to cola repair, but it only works for minor scratches on the car. 4. Toothpaste repair. If the scratches are not too severe, toothpaste can remove them. First, clean the scratches with a cloth, then squeeze toothpaste onto a damp towel or soft sponge and rub the scratches up and down. This way, small scratches will gradually fade away. 5. Nail polish repair. Since nail polish and car paint are made of the same material, applying a layer of nail polish on deep scratches can prevent them from rusting. The method is to first clean the scratched area, then apply the nail polish and let it dry.

How many kilometers does the BMW X1 need for maintenance?

BMW X1 generally requires maintenance every 10,000 kilometers or six months, whichever comes first. The specific maintenance interval for the BMW X1 model can be referred to in the car's maintenance manual. More details are as follows: 1. Maintenance cycle, generally speaking, it is every 10,000 kilometers, which means the maintenance cycle of the BMW X1 is calculated based on the time for oil and oil filter replacement. Of course, the items for each maintenance may vary slightly, as some parts and items do not need to be replaced every 10,000 kilometers like the oil. But overall, the BMW X1 maintenance cycle is set at every 10,000 kilometers or every six months, because some car owners drive less within six months, and there are quite a few who do not reach 10,000 kilometers in half a year, hence these two standards. 2. The BMW X1 enjoys a two-year unlimited mileage warranty, and the first maintenance for a new car should be done at the dealership after driving 5,000 kilometers.

Can Run-Flat Tires Be Repaired?

Run-flat tires may get punctured by sharp objects during driving, leading to air leakage. Some 4S stores recommend replacement over repair, as they need to follow the advice of tire manufacturers and carmakers. Certain automakers explicitly state that they do not endorse any tire repair methods, meaning only replacement is allowed. In reality, as long as the puncture is not too large, the tire can be repaired. Run-flat tires under the following conditions cannot be repaired. 1. The puncture is too large, exceeding 4.2 mm. 2. The puncture is located on the sidewall. 3. The tire was damaged while driving after being punctured and losing air. 4. The tire has been repaired twice already.

How to switch between D and S gears?

D gear and S gear can be switched at any time without being affected by vehicle speed or road conditions, and there is no need to press the brake. However, some CVT vehicles, in addition to the S gear button on the gear lever, also have a DS sport driving gear, which is somewhat similar to the low gear (L gear). Below is more information about D gear and S gear: 1. D gear is also known as the forward gear or drive gear, while S stands for sport mode. When the gear lever is shifted into S gear, the engine speed will remain in a higher RPM range. S gear is designed to provide the car with more powerful performance for certain actions. 2. S gear functions to make the automatic transmission drop one gear from the current gear, thereby enhancing climbing power and overtaking power. The D gear in automatic transmission cars is the most commonly used gear, suitable for general road conditions.

What do the plus and minus signs on an automatic transmission car mean?

Automatic transmission cars with plus and minus signs on the D gear are equipped with a manual-automatic transmission, which is a type of automatic transmission. Here is the relevant information: 1. First, pull the gear lever down to engage the "D" gear, then push the lever to the left until "M/S" lights up, indicating that the manual mode is engaged. When you need to shift gears, push the lever forward to downshift and pull it backward to upshift. Note that if your vehicle speed and engine speed do not meet the requirements, you will not be able to upshift. Every operation must be approved by the transmission control unit. 2. The D gear of an automatic transmission car does not have the engine braking function and will continuously shift to higher gears as the downhill speed increases, making the car go faster and faster. You must constantly use the foot brake to control the speed, which can easily cause the brakes to overheat and fail due to excessive use, which is very dangerous. Therefore, when driving an automatic transmission car on a long downhill slope, do not use the D gear.
