Below are the methods to remove small black dots on a white car: 1. Tar: If the black dots are tar attached to the car paint, you can clean them using a tar remover. Remember to wear gloves when using the tar remover. 2. Bird droppings and other impurities: If you often park under trees, your car will inevitably be attacked by bird droppings or tree sap. If the black dots are substances like bird droppings, you can soak them with car wash liquid or glass cleaner, and after softening, they can be easily removed. 3. Iron particles: If the black dots on the white car paint are dense iron particles, none of the above cleaners will work. Only specialized clay bars or cleaning cloths can be used to slowly grind them off after washing the car body.

What is the maximum age for driving with a C1 driver's license?

There is no upper age limit for holding a C1 driver's license. However, applicants aged 70 and above must pass tests for memory, judgment, and reaction abilities. Physical examination requirements: Motor vehicle drivers aged 70 and above (including 70) must undergo an annual physical examination, while those under 70 do not need to. Permitted vehicle types: The C1 driver's license allows driving small and micro passenger vehicles, as well as light and micro cargo vehicles; light, small, and micro special-purpose vehicles; and small passenger vehicles with a seating capacity of 9 or fewer. C1 driver's license holders cannot drive: large buses, tractors, city buses, medium-sized buses, large trucks, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. Additionally, a C1 license does not permit driving vehicles with more than 9 seats or trucks with a total length exceeding 6 meters.

What Are the Causes of BMW Transmission Abnormal Warning?

The main causes of abnormal transmission warnings in BMW vehicles include transmission slippage, damage to components directly related to transmission electronics, and transmission control module failure. Transmission slippage occurs due to worn clutch friction plates, surface peeling, valve body wear, and insufficient pressure. Damage to transmission electronic components happens when debris from worn clutches and valve bodies clogs solenoids. A faulty transmission control module leads to abnormal signal processing, triggering fault alerts in the vehicle monitoring system. During prolonged use, frequent gear shifting inevitably causes wear and deformation of transmission components, resulting in symptoms like difficult gear engagement, automatic gear disengagement, and operational noises. Regular full-load operational checks should be performed to observe transmission smoothness, abnormal gaps, or unusual sounds for timely troubleshooting. Solutions for abnormal warnings: 1. First scan for transmission system fault codes. 2. Identify specific transmission faults based on codes before replacing corresponding components. 3. Seek professional inspection at an automatic transmission repair center. Typically, replacing only the damaged individual components can resolve transmission issues.

Is the Tayron equipped with a dry or wet dual-clutch transmission?

The 1.4-liter version of the Tayron uses a dry dual-clutch transmission, while the 2.0-liter version is equipped with a wet dual-clutch transmission. Detailed information about dual-clutch transmissions is as follows: 1. In a dry dual-clutch transmission, the clutch connects the driving plate and the driven plate through air, directly contacting the engine flywheel. 2. A wet dual-clutch transmission uses oil to connect the driving plate and the driven plate, immersing the clutch plates in a sealed oil trough to absorb the heat they generate, significantly improving heat dissipation performance. This results in better performance in terms of shifting speed, fuel consumption, and comfort. 3. A dual-clutch transmission (DCT) has two sets of clutches in the transmission system, each connected to an input shaft—one controlling the odd-numbered gears and the other the even-numbered gears. This greatly reduces shifting time and increases efficiency, enhancing comfort during gear changes.

What Causes the Motorcycle Engine Oil Light to Illuminate?

Analysis and solutions for the motorcycle engine oil light illumination: 1. Insufficient engine oil level, leading to inadequate lubrication and low oil pressure. Solution: Top up oil. 2. Dirty or thickened oil preventing the oil pump from effectively circulating oil, causing low or no oil pressure. Solution: Change oil. 3. Thin oil or thinning due to high engine temperature, resulting in leakage through engine gaps and low oil pressure. Solution: Change oil or inspect cooling system. 4. Oil pipe leakage or oil pump damage/excessive wear reducing oil circulation, leading to low or no oil pressure. Solution: Inspect and repair. 5. Excessive clearance between crankshaft and bearings causing oil leakage and low pressure. Solution: Repair. 6. Faulty pressure relief valve due to weak/ stuck spring or damaged ball, reducing oil pressure. Solution: Replace or repair. 7. Oil sensor, pressure gauge, or electrical circuit malfunction causing low oil pressure. Solution: Replace or inspect.

What are the battery specifications of the Baojun 730?

The Baojun 730 uses a Camel brand 86550T-12V-55Ah-550CCA battery. The car battery is installed in an appropriate location with special safety features. If the battery must be replaced, ensure the new battery's electromagnetic compatibility, dimensions, maintenance, output power, and safety requirements are considered before purchase. Here are the relevant details: 1. Checking the electrolyte level of a battery with an inspection eye: (1) To clearly identify the color inside the circular window on the battery, ensure sufficient lighting. Never use an open flame or sparking items for illumination. (2) The circular window on the upper part of the car battery changes color based on the electrolyte level. 2. Checking the electrolyte level of a battery without an inspection eye: (1) The electrolyte level should always be between the "Min" and "Max" marks on the side of the battery and should never exceed the "Max" mark. (2) If the electrolyte level is below or near the "Min" mark, the battery should be replaced immediately.

How to Confirm ETC is Functioning Properly?

Methods to check if ETC is functioning properly: Manually insert and remove the card once. If there is a sound, it indicates that the ETC is in normal working condition. ETC working principle: Through the dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station, computer networking technology is used to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping while being able to pay highway or bridge fees. Where can ETC be installed: For small vehicles such as cars and minivans, the OBU device is installed in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, the installation position is in the middle and lower part. ETC installation position requirements: The height should not be less than 1.2 meters or higher than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane).
