If the vehicle's body color is changed by more than 30%, you must visit the vehicle management office within 10 days to take new photos and apply for a modification registration in order to pass the annual inspection. The rear spoiler cannot be too large. Body aerodynamic kits, including side skirts, spoilers, and rear wings, do not require modification registration at the vehicle management office. Wheels can be modified, provided that the original factory size is maintained. If the wheels are of the same size but different style, modifications are allowed without restrictions. Modifying brake discs and calipers is not restricted, as long as the braking performance meets the annual inspection standards. Brake upgrades do not affect the annual inspection. Suspension modifications are not permitted, as they alter the vehicle's structure and are considered illegal modifications.

As a seasoned car enthusiast passionate about vehicle modifications, I've found that while transforming a BJ80 to resemble a Mercedes-Benz G-Class is visually appealing, strict adherence to legality is crucial for safety and reliability. The key lies in avoiding infringement on Mercedes' design patents, particularly by not directly replicating iconic elements like the grille or emblem. Practically, opt for certified non-infringing modification kits available on the market, some of which are custom-designed for the BJ80. Post-modification, mandatory registration of the altered specifications with local vehicle management authorities is essential—failure to do so risks penalties or impoundment for illegal modifications. Prioritize safety by preserving the vehicle's structural frame and chassis to maintain crash protection integrity. Consulting professional modification shops beforehand is highly recommended; their expertise ensures compliant part selection and a hassle-free process. Remember, legality is paramount—enjoy personalized driving pleasures while staying firmly within regulatory boundaries.

How to solve fault code p0606?

Fault code p0606 can be resolved as follows: After this fault code appears, first delete it and observe whether it reappears. If it reappears quickly, in most cases it means that the electronic control module or original factory parts need to be replaced. Below is an extended introduction: 1. Fault code p0606 means that there is a fault in the electronic control unit (ECU). This fault code may appear due to the use of non-original factory parts. 2. After troubleshooting the car, it is often necessary to clear the fault code. When clearing the code, be sure to follow the fault code clearing method specified for the specific vehicle model. Never directly disconnect the negative ground wire to clear the fault code.

What is the appropriate color temperature for headlights?

The color temperature should be between 3500K and 5000K, with 4300K generally providing the best lighting effect. If the color temperature is too high, the light will appear bluish (or even purplish at higher levels). Such color temperatures have poor penetration in hazy weather conditions, which can easily lead to safety issues. Here is an introduction to automotive xenon headlights: 1. The full name of xenon headlights is HID (High Intensity Discharge Lamp). They use a matching electronic ballast to instantly boost the car battery's 12V voltage to a triggering voltage of over 23KV, ionizing the xenon gas in the headlight to form an arc discharge and maintain stable illumination, providing a stable automotive headlight system. 2. Xenon lamps break away from the tungsten filament lighting principle invented by Edison. They are filled with high-pressure inert gas—Xenon—inside a quartz tube, replacing the traditional filament. Mercury and carbon compounds are present at the two electrodes, and the xenon gas is stimulated to emit light by a 23,000-volt high-voltage current through the ballast, creating a perfect white arc between the electrodes. The light emitted closely resembles nearly perfect sunlight.

How to solve Peugeot fault code P0420?

When the P0420 fault code appears in a car, it mainly indicates that the conversion efficiency of the catalytic converter is below the threshold value. The possible cause is a damaged catalytic converter. Here are 3 quick solutions to resolve the Peugeot fault code P0420: 1. Replace the vehicle's original catalytic converter (avoid using aftermarket parts as they may not last long and the fault light could reappear). 2. Install a TDTAS fault code eliminator or similar component to repair the data and clear the P0420 fault light. 3. Use a car diagnostic tool to access the engine ECU and disable the P0420 fault code (this method may work for some vehicles but not all).

How to solve the P1297 trouble code?

P1297 trouble code causes and solutions are as follows: 1. The P1297 trouble code means the electric load sensor circuit voltage is too low. When the vehicle's charging system load increases due to car lighting or rear window heating, it can send an electronic signal to the ECU to control idle speed and resolve the issue. 2. P1297 can also indicate a pressure difference between the exhaust turbocharger and throttle valve. This fault may be caused by throttle valve damage, which can be resolved by inspecting and replacing the throttle valve. Here is some extended information: 1. During vehicle operation, component aging, damage, missing parts, or functional abnormalities are inevitable. When the components don't match the information stored in the control unit, specific trouble codes are generated within the control unit. These codes are translated into professional terms familiar to technicians through specialized diagnostic tools, while also providing important data streams at the time of the fault. 2. Trouble codes are stored in registers for easy reading and analysis, and can also alert drivers through instrument displays or warning sounds.

What car brand is represented by five vertical lines?

Five vertical lines represent the WM Motor, which is a Chinese independently produced pure electric vehicle. Below is an extended introduction: 1. The logo of WM Motor consists of five vertical lines, symbolizing cloud services, platform, people, automobiles, and multi-channel. These five elements represent WM Motor's production and sales philosophy, with the five lines continuously interacting and interconnected. 2. Currently, WM Motor has only released one pure electric vehicle, positioned as a pure electric intelligent SUV. This model is called the WM EX5 and is also the first mass-produced vehicle by WM Motor. The WM EX5 features front-wheel drive, with a front suspension system comprising a MacPherson strut independent suspension with a stabilizer bar, and a rear suspension system with a variable cross-section torsion beam suspension. The front face of the WM EX5 adopts the common closed grille design for electric vehicles, with the WM Motor logo on the charging cover that can display battery information, giving it a certain technological feel.

Is Transmission Fluid Basically Unnecessary to Replace?

Transmission fluid basically does not need to be replaced is a misconception. Here are the reasons: 1. Transmission fluid is a consumable item. During vehicle operation, the transmission generates friction, producing fine debris and impurities, causing the transmission fluid to become cloudy and its performance to degrade. This affects the transmission's operation and may lead to driving issues, necessitating replacement. 2. Depending on the type of transmission, transmission fluid can be categorized into automatic transmission fluid (ATF) and manual transmission fluid. Generally, manual transmission fluid has a longer service life than automatic transmission fluid. Manual transmission fluid should be replaced approximately every 3 years or after driving 80,000 to 100,000 kilometers, while automatic transmission fluid needs replacement every 2 years or after driving 50,000 to 80,000 kilometers.
