The reasons for the clicking sound in the transmission when the clutch is not engaged: Wear and damage of bearings: When bearings wear out, the gap increases, and the fitting precision decreases. When bearings are damaged, abnormal sounds occur as they cannot operate normally, potentially leading to damage of transmission components and exacerbating the issue. This can also result from the wear of transmission components or the use of replacement parts with excessively low precision, such as worn gears or new gears with excessive clearance compared to the original ones. Insufficient or overly viscous lubrication oil causing poor lubrication: In such cases, the corresponding lubricating oil (grease) should be replaced; otherwise, it will accelerate the wear of the transmission and shorten its service life. Loose bolts on the transmission housing (end cover): Vibrations during operation can loosen the bolts, so regular inspections are recommended.

Can Modified Xenon Headlights Pass Annual Inspection?

Modified xenon headlights can pass the annual inspection if the xenon bulbs are equipped with lenses and the color temperature is below 6000 lumens. Below are specific details about installing lenses: 1. Lens Selection: As long as the lens does not affect the headlight's illumination capability, it generally can pass the inspection. If the high-end model comes with lenses, you can opt for the original lenses, and in this case, no registration is required. Installing suitable lenses can improve the issue of scattered light from the original headlights, greatly enhancing nighttime driving safety. 2. Penalty Explanation: According to Article 90 of the Road Traffic Safety Law, unauthorized installation of lenses or xenon headlights is considered an illegal modification that violates vehicle safety principles, punishable by a fine and 3 demerit points.

How long does it usually take to pick up a car after purchase?

You can pick up the car on the same day of purchase. Here is relevant information about car pickup: 1. License plate registration time: It takes about three days from picking up the new car to getting the license plate. Prepare a temporary license plate, and pay close attention to its expiration date. Using an expired temporary plate may result in insurance claim rejection by the insurer. Then proceed with the local license plate registration. The car owner needs to prepare: the original and a copy of the vehicle qualification certificate; the original purchase invoice (three copies in total); the owner's ID card and insurance policy. With these materials ready, you can go to the local vehicle management office for procedures such as vehicle inspection, payment of vehicle purchase tax, license plate selection, and processing the vehicle license. 2. Precautions: Check the odometer mileage. If you find the mileage of the new car is unusually high, inquire with the 4S store immediately or request a replacement; check the vehicle's manufacturing date—the closer the production date is to the pickup date, the better. The specific location of the manufacturing plate is usually on the door frame on the driver's side; perform an exterior inspection, mainly to check if there are any color differences or scratches on the new car's paint.

Is it illegal to install a front splitter on a car?

Installing a front splitter on a car is illegal. Here are the specific details about the scope of illegal car modifications: 1. Widebody modifications and installation of oversized tires: Modifications to the intake and exhaust systems can affect the overall performance of the vehicle and are detrimental to driving safety, making them prohibited areas for modifications. 2. Chassis modifications: Raising or lowering the chassis constitutes structural modifications to the vehicle. 3. Headlight modifications: These not only affect the visibility of pedestrians and other drivers but also make the vehicle fail the annual inspection. 4. Engine modifications: Such as reprogramming the engine ECU, installing a strut bar in the engine bay, adding a turbocharger, or a supercharger. While these modifications may significantly enhance performance, they greatly limit the engine's lifespan and may lead to premature engine failure.

What are the reasons why an electric vehicle cannot be charged?

If the vehicle cannot be charged, it may be due to a damaged battery, a faulty charger, or a malfunctioning controller. In such cases, you can try replacing the charger first. If the issue persists, the problem likely lies with the battery or controller. Below is more information about electric vehicle batteries: 1. Function of the battery: The battery is a crucial component in an electric vehicle, responsible for storing electrical energy. Without a functioning battery, the vehicle cannot operate normally. However, batteries are wear-prone parts, and their performance degrades over time with repeated charging and discharging cycles. Therefore, batteries require periodic replacement. 2. Function of the controller: The controller is another essential component in an electric vehicle, managing the entire electrical system. Without a controller, the vehicle cannot function properly. The controller is typically located under the rear seat and can be replaced separately. 3. Proper usage habits: When using an electric vehicle, it's important to avoid overcharging or deep discharging. After riding, do not charge the battery immediately, as the battery temperature is still high. Charging at this point can cause the temperature to rise further.
