There is something stuck to the radar or a signal error. Specific reasons: Something is stuck to the reversing radar probe, causing signal blockage; The rear wiper water pipe is leaking or has seeped into the reversing radar system; The radar ultrasonic signal is faulty, causing false alarms; The reversing radar circuit is short-circuited or the radar module is malfunctioning. Solutions: Check if there is anything blocking the radar holes at the rear of the vehicle. Seal the leak (or replace the pipe) and drain any accumulated water in the radar system. Restart the engine, drive the vehicle to an open area, and try reversing again to observe the result. Take the car to a 4S shop or repair shop for inspection, checking the circuit or replacing the radar module.

I've been driving for over a decade, and the most common cause of reverse beeping in Volkswagen cars is rear radar issues. The radar sensors mounted on the bumper can easily get blocked by mud, leaves, or ice, causing the system to falsely detect obstacles and keep beeping. In such cases, get out and gently wipe the sensors clean with a soft cloth - avoid using stiff brushes that might scratch them. Then try turning the engine off and restarting, which usually solves the problem. If the beeping persists, it might be loose sensor wiring or water-induced short circuits. My old Golf once had this issue - the repair shop found a blown fuse, and replacing it for just a few dollars fixed it. Volkswagen's radar system is highly sensitive but prone to minor glitches in bad weather. Remember to clean the sensor areas during regular car washes. Continuous beeping isn't just annoying - it's dangerous. Ignoring the warning could lead to scraping other vehicles, so prompt attention is always the best approach.

How Often Should Windshield Wipers Be Replaced?

Wiper blades have a lifespan of one year, and it is recommended to replace them annually. Here is some relevant information about wiper blades: Operating Principle: The power source of the wiper blades comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanism. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into a left-right oscillating motion. Precautions: The key to the effective performance of wiper blades is that the rubber wiper strips maintain sufficient moisture. Only with sufficient moisture can they maintain excellent flexibility and ensure close contact with the windshield.

Should You Engage the Parking Brake or Shift to P First in an Automatic Transmission?

In an automatic transmission, you should shift to P first and then engage the parking brake. Below is relevant information about automatic transmissions: Types of Transmissions: There are mainly two types of automatic transmissions used in vehicles. One is the stepped automatic transmission, and the other is the continuously variable transmission (CVT). The most commonly used in passenger cars is the mechanical CVT, which utilizes a V-shaped metal belt or chain to transmit torque between the driving and driven pulleys. This transmission method is typically used in smaller vehicles. Operational Characteristics: In modern automatic transmission vehicles, the driver only needs to control the accelerator pedal. The computer analyzes signals from sensors that detect the engine throttle opening and vehicle speed, automatically controlling gear shifts or engaging different gears. Generally, automatic transmissions result in some power loss from the engine. The greatest advantage of automatic transmission vehicles is convenience, especially in traffic jams. The benefits are even more pronounced when encountering uphill traffic congestion. Nowadays, automatic transmission vehicles are becoming increasingly popular. From the perspective of advanced automotive development countries, most vehicles are transitioning to fully automatic transmissions. The trend in automotive development is for automatic transmissions to replace manual transmissions as the primary choice for daily driving.

Can I choose a license plate number when buying a car at a 4S shop?

You can choose a license plate number when buying a car at a 4S shop. After payment and car reservation, the 4S shop will ask for your ID card to process the license plate registration. If your city offers online number selection, you can directly choose your number online in advance and receive the physical plate a few days later. Documents required for new car license plate registration: Original and photocopy of ID card (if processing for someone else, both your ID and the car owner's ID must be provided). Original and photocopy of the invoice. Original and photocopy of the vehicle qualification certificate. Original and photocopy of the compulsory insurance policy. Tax payment certificate. Procedures for license plate replacement: In addition to the vehicle's registration certificate and your ID card, you must bring the motor vehicle registration certificate if it has already been processed. For company vehicles, the organization code certificate is also required. Fill out a license plate replacement application form at the vehicle management office (company vehicles must be stamped with the official seal). The vehicle management office will issue a police receipt and a temporary license plate. The temporary license plate must be placed on the front windshield for inspection. Using a temporary license plate does not affect the annual inspection. If only one license plate is lost, the old one must be surrendered when applying for a replacement. After 30 working days, you can collect the new license plate from the vehicle management office. The new license plate will have the same number as the original, and the vehicle registration certificate can still be used. Things to note when selecting a license plate number at a 4S shop: Assistance: Generally, buying a new car is simple, as the 4S shop staff will assist with the process. You only need to pay the corresponding fees. Documents: Keep all purchase documents for the new car. This is a necessary step. After purchasing the car, ensure you keep all receipts, signed documents, and tax payment certificates. Purchase tax: Vehicle purchase tax must be paid. This is a mandatory fee for every car owner, so the first thing after buying a car is to pay the purchase tax. Keep this certificate as well. Insurance: Vehicle insurance must be purchased. Insurance is essential because motor vehicles are inherently risky, and you cannot select a license plate number without insurance. Safety technical inspection: Drive the car to the inspection area for an inspection by the inspector. Submission of materials: ID card (for company vehicles, provide a business license with a unified social credit code), identity proof of the agent, a power of attorney with an official seal, and a residence permit for non-local residents. Proof of car purchase origin (invoice), vehicle purchase tax payment certificate or tax exemption certificate, and vehicle qualification certificate or import certificate for imported vehicles. License plate selection: You can select a license plate number via a mobile app or on-site. Methods for selecting a new car license plate number: "Self-selection": Submit the self-selection confirmation form and payment invoice to the vehicle management office to process the license plate and receive the vehicle registration certificate, inspection certificate, and temporary license plate. "Online selection": Submit the online self-selection confirmation form and payment invoice to the vehicle management office to process the license plate and receive the vehicle registration certificate, inspection certificate, and temporary license plate. "Random selection (10 options)": Submit the selection form and payment invoice to the vehicle management office to process the license plate and receive the vehicle registration certificate and inspection certificate. Then collect and install the license plate at the designated location. License plate selection rules on the Traffic Police 12123 App: Pre-selection is available daily from 8 AM to 10 PM. You have 20 chances to self-select a number, and only number segments released over 7 days ago are eligible for self-selection. Random selection offers 5 attempts, with 10 numbers per attempt and 90 seconds per batch. You can check online if your desired number is already registered to avoid wasting a self-selection chance. Note that number segments released within the last 7 days can only be selected randomly, not self-selected. You can start with random selection, which is faster and may yield good numbers. Each batch has a 90-second display time. If random selection doesn't yield a satisfactory number, you can switch to self-selection. Self-selected numbers follow a specific order, and if your first choice is available, you can take it immediately. Pay attention to the order of self-selected numbers.

What are the major causes of engine vibration?

Engine vibration causes: Poor fuel combustion: The automobile engine is the device that provides power for the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. The quality of the engine is also related to the fuel. If the fuel quality is poor, natural problems will occur. Moreover, incomplete fuel combustion can lead to serious engine carbon buildup issues. Spark plug failure: The spark plug is a crucial component of the gasoline engine ignition system. It introduces high voltage electricity into the combustion chamber and causes it to jump across the electrode gap to produce a spark, thereby igniting the combustible mixture in the cylinder. If the spark plug fails, it can result in insufficient ignition energy, causing engine problems.
