The front parking radar failure in the Volkswagen Magotan is typically caused by poor contact or power supply issues with the radar host's power line, or a malfunction in the front radar sensors. It is recommended to visit a local 4S shop to replace the power line or troubleshoot the circuit for a resolution. Parameters of the Magotan 2020 model: Length*Width*Height 4865*1832*1471 (mm), equipped with a 7-speed dry dual-clutch transmission, maximum torque of 250 (N·m), and maximum power of 110 (kW). Functions of the front parking radar: Accurately measures the distance between the rear of the car and the nearest obstacle. When reversing to the limit distance, it emits an urgent warning sound to remind the driver to brake. Repeats voice warning sounds to alert pedestrians. The functions of front radars vary among different vehicles. For private cars, most high-end models come with parking radars and rearview cameras to assist the driver in viewing the rear situation. Some even more advanced vehicles are equipped with front radars or cameras to help the driver control the front distance during parking. The primary function of front radars is to assist in parking. Working principle of the parking radar: The parking radar works by utilizing ultrasonic signals. Controlled by the microcomputer inside the radar host, the signals are transmitted and received by the probes. The distance to the obstacle is calculated by comparing the signal's return time, and then the alarm emits different warning sounds accordingly. The parking radar system consists of the parking radar ECU, the parking radar buzzer, and several parking radar sensors installed on the bumper. If a rear camera is installed, it provides an image of the rear area of the vehicle on the navigation screen. When the vehicle is shifted into reverse gear, the parking radar ECU uses ultrasonic sensors to monitor the area around the rear bumper. If an object is detected within the monitored area, the sound alarm device in the instrument cluster emits an audible warning.

Why does the car shake severely when starting?

The reasons for severe shaking when starting the car: 1. Engine mount issue: If the car shakes while idling in place, the engine mount needs to be replaced; 2. Carbon deposit problem: Excessive carbon deposits on the pistons or spark plugs can cause the fuel injected by the fuel injector to be absorbed by the carbon deposits during cold starts, preventing it from participating in combustion. This leads to incorrect air-fuel mixture, unstable idling, shaking, or even misfiring; 3. Incorrect air-fuel mixture ratio: This involves multiple factors, such as the atomization condition of the fuel injector, the ignition condition of the spark plugs, the data from the intake pressure sensor, the air intake data from the mass air flow sensor, the fuel pump pressure issue during cold starts, and the environmental temperature data from the ECU, all of which need to be checked.

Is a 6-seater vehicle exempt from inspection for 6 years?

6-seater vehicles are exempt from inspection for 6 years. According to regulations: non-operational passenger cars and other small, mini passenger vehicles (excluding vans and vehicles with 7 or more seats) within 6 years of initial registration are exempt from inspection. After the 6-year period, starting from the 7th year, they require annual mandatory inspections. For non-operational small private passenger vehicles with 6 or fewer seats, the 6-year exemption means the vehicle is exempt from on-site inspection, but the owner still needs to apply for the inspection compliance label at designated vehicle management offices, motor vehicle registration service stations, or traffic police substations within specified periods, and affix it to the upper right corner of the windshield. Vehicle annual inspection refers to the mandatory safety technical examination conducted yearly for vehicles that have obtained formal license plates and registration certificates.

Do You Need to Press the Clutch When Shifting Gears in a Manual Transmission Car?

Shifting gears in a manual transmission car requires pressing the clutch. The functions of the clutch are: 1. Gradually increasing the driving force to allow the car to start smoothly; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration impact from the engine and extending the lifespan of transmission gears. The working process of the clutch is: 1. When the clutch pedal is pressed, the push rod moves the master cylinder piston to increase hydraulic pressure; 2. The pressure travels through the hose to the slave cylinder, forcing the slave cylinder rod to push the release fork, which moves the release bearing forward; 3. When the clutch pedal is released, the hydraulic pressure is relieved; 4. The release fork gradually returns to its original position under the action of the return spring, and the clutch re-engages.

What transmission does the Geely Icon use?

Geely Icon is equipped with a seven-speed dual-clutch transmission across all models. Here is some relevant knowledge about dual-clutch transmissions: Working principle of dual-clutch transmission: A dual-clutch transmission consists of two sets of manual transmissions. Generally, adjacent gears are arranged alternately on the two sets of gears, and two clutches respectively control the connection and disconnection between the two sets of gears and the engine. Advantages of dual-clutch transmission: The dual-clutch transmission combines the advantages of manual and automatic transmissions. Instead of using a torque converter, it employs two sets of clutches that work alternately to achieve seamless gear shifting. Since there is no hydraulic torque converter, the engine's power can be fully utilized, and the alternating operation of the two clutches results in extremely short shift times.

What is the principle of a 360-degree panoramic camera?

360-degree panoramic camera works by using cameras mounted on the front and rear mirrors of the car to achieve all-round monitoring. When the 360-degree panoramic assist system is activated, the cameras on the car will upload the captured images to the vehicle's computer. The computer then processes the images to simulate a bird's-eye view of the car, achieving the 360-degree panoramic effect. The functions of the 360-degree panoramic camera include: 1. Recording driving footage synchronously with four ultra-clear cameras while driving; 2. Displaying images around the car body on the screen while driving to eliminate blind spots; 3. Automatically triggering the rearview image when reversing, allowing the driver to accurately determine if there are obstacles behind the car and guiding the driver on the trajectory the wheels will follow; 4. Equipped with a built-in vibration sensor that automatically records footage upon detecting vibration.
