Modifying the original factory model by replacing, adding, or removing parts or altering its appearance. Car modification is not illegal if it is done within the reasonable limits of the law. According to Article 16 of the 'Road Traffic Safety Law of the People's Republic of China': The first provision states that no unit or individual may assemble motor vehicles or alter the registered structure, construction, or characteristics of motor vehicles without authorization. Before modifying a vehicle: A professional modification technician mentioned that vehicle owners should apply to the vehicle management office in advance before modifying their vehicles. After modification, they need to fill out forms, take new photos, and update the vehicle registration certificate photo. However, the technician also pointed out that certain parts of the car cannot be modified, such as the shape of the headlights, and the engine cannot be replaced unless it is damaged. If one wants to replace the engine, proof from the insurance company or other relevant parties is required to justify the necessity of the replacement.

I'm really into car modifications and have been tinkering with them since my school days. Once, I modified the rims and headlights, which looked really cool, but whether the modifications are legal depends on what you change. For example, switching to smaller-sized rims or applying a car wrap is allowed in many places, as long as you register the changes with the DMV. However, if you modify the engine power, exhaust system, or chassis, that's definitely illegal because the law prohibits altering the vehicle's structure and safety features. You could face fines or even have your car impounded. My friend got fined because he modified his exhaust system, making it too loud, and a neighbor reported him. While modifications can be fun, safety comes first. I recommend checking the regulations online or consulting an expert before making changes. Don't risk accidents just to look cool, as insurance won't cover it.

How long should you drive before getting a car service?

Car maintenance is typically required every 5,000 kilometers or every six months, which generally involves changing the engine oil, oil filter, and air filter. Engine oil serves multiple functions including cooling, lubrication, cleaning, and sealing, playing a crucial role in ensuring the engine operates properly. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing. The scope of car maintenance primarily includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more.

Will the car's misfire trigger the malfunction indicator light?

Car misfire will trigger the malfunction indicator light, usually a yellow warning light. After engine misfire occurs, the vehicle will experience increased fuel consumption, black smoke emission, weak acceleration, severe vibration, and louder engine noise. It's also prone to stalling. The method to diagnose misfire is relatively simple: sequentially disconnect spark plug wires or fuel injector connectors while the engine is running. For normally functioning cylinders, cutting off spark or fuel will cause obvious engine reaction, while non-functioning cylinders will show almost no change in engine operation. Another method is to use an infrared thermometer to measure exhaust pipe temperature - the exhaust temperature of non-firing cylinders will be significantly lower than that of firing cylinders.

What is the issue with the Haval H6 transmission failure?

Haval H6 transmission failure is caused by improper operation or lack of timely maintenance. If the transmission malfunctions, it is necessary to promptly visit a 4S shop for repairs. The Haval H6 is a compact SUV under the Haval brand. The Haval H6 is equipped with two engines: a 1.5-liter turbocharged engine and a 2.0-liter turbocharged engine. As the flagship model of the Haval brand, the Haval H6 is positioned as an urban intelligent SUV and was launched at the Great Wall Motors Tianjin new factory. It offers Mitsubishi 2.0L gasoline-powered models and Green Power 2.0T diesel models, available in three versions: Urban, Elite, and Premium.

What is the wading depth of the Q5L?

The maximum wading depth of the Audi Q5L is 600mm. The wading depth of the Audi Q5L is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the Audi Q5L is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause serious damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, the auto start-stop function must be turned off to prevent the engine from automatically restarting after stalling in the water, which could cause serious damage due to water ingress. Based on the situation of the vehicle ahead, assess the underwater road conditions and choose a suitable entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. For roads prone to waterlogging, observe warning water level markers, trees, or other reference points such as the wheels and doors of other vehicles to judge the water depth before deciding whether to proceed. Understand your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not enter the water recklessly; choose an alternative route instead.

Can car air conditioning be directly charged with refrigerant without vacuuming?

Car air conditioning cannot be directly charged with refrigerant without vacuuming. If the vacuum is not thoroughly performed, the air conditioning will not work effectively. Moisture in the air can freeze and block the expansion valve during cooling, and the high-pressure gauge needle will continuously fluctuate. Hazards of charging refrigerant without vacuuming in car air conditioning: It can cause the compressor's exhaust temperature to be higher than the refrigerant gas temperature; when air enters the system, the condensation pressure will gradually increase; the gas layer formed on the inner surface of the condenser's heat transfer tubes will increase thermal resistance, thereby reducing the condenser's heat dissipation capacity; water reacting with the refrigerant can produce acidic substances, leading to corrosion of pipes and equipment; water and refrigerant are immiscible, resulting in ice blockage at the expansion valve's throttle orifice. Correct method for charging refrigerant in car air conditioning: Prepare a complete and qualified refrigerant charging tool; connect the car air conditioning system to the charging tool adapter; perform vacuuming; inject liquid refrigerant from the high-pressure side to complete the refrigerant charging process.

What does the A on the car dashboard mean?

There are two scenarios when the letter A appears on the car dashboard: one represents mileage counting, and the other indicates that the auto start-stop function is deactivated. Typically, a car's odometer can display two separate mileage counts - one showing the total distance traveled, and another for individual trip counting, which can be toggled using the black button on the dashboard. When switched to A, it can be used to calculate the distance traveled on a full tank of fuel (reset after refueling), track maintenance intervals, or display the distance between two locations. To reset, simply press and hold the black button. If the auto start-stop is turned off, the dashboard will display a circled A with OFF underneath (some models show a circled A with a slash through it).
